Obviating some of the traditional manufacturing and alloy design barriers,
additive manufacturing (AM) makes possible complicated micro-/nano-structures
and geometries, which cannot be obtained via conventional manufacturing.
Advanced materials, which can outperform their conventional counterparts, are
actively being designed with substantially distinctive microstructural
features. This symposium invites submissions that focus on exploiting the
unique characteristics of AM to design and develop advanced structural or
functional materials, employing a “First-Principles” or “Materials by Design”
approach.
This symposium will feature a comprehensive exploration of the fundamental
physical metallurgy and alloy design principles for AM, leveraging the power of
advanced characterization techniques, computer simulations, and analytical
theory to unlock insights into materials behavior. A significant emphasis of
the symposium is placed on alloy design principles, strengthened by the
integration of state-of-the-art characterization techniques, such as atom-probe
tomography (APT), scanning/transmission electron microscopy (S/TEM), electron
backscatter diffraction (EBSD), X-ray diffraction (XRD), and 4D scanning
transmission electron microscopy (4D-STEM) in combination or correlatively.
These cutting-edge techniques combined with analytical theory, and mathematical
and physical simulations provide researchers with the tools to study AM
materials at a hierarchy of relevant length scales, allowing for a holistic and
nuanced understanding of their far-from-equilibrium structures, as well as
their physical and mechanical properties. Discussions surrounding the synergies
between Integrated Computational Materials Engineering (ICME), physical
simulations and real-world experiments, which highlight the potential of this
combined approach in advancing AM materials research are encouraged. By
bringing together experts in physical and mechanical metallurgy, advanced
characterization techniques, ICME, and thermodynamics, the symposium aims to
propel the field toward innovative breakthroughs in materials design for AM.
Abstracts of fundamental or applied research are invited in the following
subject areas:
-Introduction of novel structural or functional alloys designed specifically
for additive manufacturing, including but not limited to: light metals (Al, Ti,
Mg), steels, ferrous alloys, high-temperature alloys (Ni-, Fe-Ni- or Co-based
superalloys), refractory alloys (Re, W), and high-entropy alloys.
- Micro-/nano-structure evolutions and phase transformations, including new
stable or metastable phases formed under AM solidification conditions, which
can be utilized to enhance the mechanical or physical properties of
materials.
- Mechanical behavior
- Physical behavior
Advances in characterization technology have greatly improved our ability to
quantify deformation mechanisms such as dislocation motion, twinning, and
stress-induced phase transformations, and the microstructural changes
accompanying deformation such as texture evolution, grain morphology changes,
dislocation accumulation and localized strain. A variety of relatively new
techniques are being applied to both structural and functional materials. In
combination with modeling, these techniques improve our understanding of
deformation and failure during material processing/forming and under normal or
extreme conditions in service. In situ techniques, especially, are providing an
enhanced understanding of individual mechanisms, their interactions, and the
direct validation of simulations from computational materials science models.
This gathering offers a venue to discuss and share new advances in current
techniques or new technique development or in pairing with algorithms or
simulations as they apply to deformation behavior.
Areas of interest include, but are not limited to:
* Improving the understanding of deformation mechanisms in structural or
functional materials – elasticity, dislocation plasticity, mechanically-induced
twinning or phase transformations, damage and fracture
* Advances in characterization techniques: X-ray-based techniques,
electron-based techniques (including HR-(S)TEM, EBSD, HR-EBSD, ECCI, PED),
scanning probe microscopy techniques, and others – in particular in-situ
* Advances in materials deformation modeling– with specific emphasis on the
integration with advanced characterization techniques
Real time observations can provide important information needed to understand
materials behavior, as these techniques can provide temporal and spatial
insights free from artifacts otherwise induced from conventional experimental
techniques. Traditional and emerging advanced imaging techniques, which may be
optical or non-optical, would allow such observations. Methods may be enhanced
with capabilities that enable heating and cooling, controlled atmospheres, and
application of stresses; and can be used to generate real time thermodynamic
and kinetic data needed to study a variety of materials and processes. This
symposium encompasses a broad range of materials science topics enabling
cross-cutting opportunities for multiple disciplines (biomaterials, energy
materials, functional materials, structural materials, etc.) while topics will
be separately categorized in the technical program. Presentations are solicited
on the application of these methods to materials science and industrial
processes, as well as on development of such techniques.
Topics include, but not limited to:
• Studies using real time optical (e.g., visible light, white light, laser, IR,
and UV) and non-optical (e.g., scanning probe, electron, and ultrasound)
imaging techniques
• Researches using in-situ, in-operando, in-vitro, and in-vivo observation
imaging techniques, such as thermal imaging furnace and other real time imaging
methods
• Confocal techniques, including fluorescence and reflection types, which may
be equipped with capabilities such as heating/cooling chambers, gas chambers,
mechanical testing, Raman spectroscope, mass spectrometry, and FTIR
• Microscopic or telescopic imaging methods include hot thermocouple,
resistance heating, and sessile drop techniques used for high temperature
phenomena.
• Thermodynamic and kinetic data from these techniques, useful for phase
diagram constructions, oxidation/corrosion modeling, phase formation kinetics
studies, etc.
• Work using high speed and slow speed cameras
• Materials used in manufacturing real time imaging devices
• Novel technologies and methodologies for emerging imaging devices
A joint session with the following symposium may take place:
• The Mechanical Response of Materials Investigated through Novel In-situ
Experiments and Modeling symposium
Respective papers may participate in part of the dedicated joint session.
This symposium will highlight cutting-edge research in coherent and phase
contrast imaging techniques, including x-ray and electron-based approaches like
coherent diffraction imaging (CDI), ptychography, holography, and advanced
phase contrast imaging (PCI) methods. We will explore their applications across
diverse materials classes and delve into the integration of modeling,
simulation, and artificial intelligence (AI) for enhanced characterization and
analysis. The symposium will also bring in discussions on the new challenges in
the era of diffraction limited storage rings (DLSR). We hope this symposium
will help to foster collaboration and advance the field of coherent and phase
contrast imaging.
Background and Rationale:
A high degree of spatial coherence is an attractive property in x-ray and
electron beams. In some cases, these imaging methods provide resolution beyond
that achieved with optics and can also provide remarkable sensitivity to a
variety of contrast mechanisms. Various novel x-ray and electron coherent
imaging methods have been developed and optimized, leading to rapid growth in
applications over the past decades. It is expected that coherent imaging
technical developments and applications will get a further boost in the era of
DLSRs. More than a dozen DLSR facilities are currently operational or in the
planning stage, providing unprecedented high-quality coherent x-ray sources.
The two methods that will be the focus of this symposium are CDI and PCI with
both x-rays and electrons. Both directly utilize the coherence properties of
the incident beams. CDI has rapidly advanced in the last twenty years to allow
characterization of a broad range of materials, including nanoparticles,
strained crystals, micro-electronic chips, biomaterials and cells. PCI has been
widely employed in dynamics and engineering studies of materials, geophysics,
medicine and biology. These highly sensitive imaging techniques enable
characterizing the structures of real materials under real conditions in real
time.
Advanced material modeling methods at the atomistic and continuum scales,
including AI-based methods, are being used in conjunction with these imaging
techniques to enhance their capability. The integration of AI, modeling,
experiment not only makes reliable predictions at spatio-temporal scales in a
broad range possible but also reduces the experimental measurement time, dose
on the sample and amount of data. This is critical in the CDI and PCI
applications in DLSR sources.
On the one hand, the highly coherent X-ray sources based on DLSR would allow
faster experiments at better precision and sensitivity in shorter time. On the
other hand, the higher coherent flux may bring in more artifacts from
surrounding materials other than the samples and enforce more severe radiation
effects in the measurements. How to utilize these brilliant new sources wisely
is a new challenge in the DLSR era. We will have a special session dedicated to
the CDI/PCI developments and scientific applications from the new sources.
Areas of interest include, but are not limited to:
1. All coherent and phase contrast X-ray-based techniques including Bragg CDI,
Fresnel CDI, ptychographic CDI, propagation phase contrast imaging,
interferometry imaging, and analyzer-based phase-contrast imaging.
2. All electron-based techniques including ptychography and electron CDI.
3. High performance computing (HPC) and AI to accelerate data analysis, improve
image quality, imaging speed/efficiency, and autonomously steer experiments.
4. Digital twins to inform high-resolution imaging experiments.
5. All structural and functional materials systems needing high resolution
imaging.
6. Industrial applications
7. Developments of new CDI/PCI experimental protocols.
8. New sample preparation protocols.
Logistics: This is a rapidly evolving field and has an increasingly large
presence at TMS. We had great success with our first five symposiums. The first
held in 2013 in San Antonio and then in 2015 (Orlando), 2017 (San Diego), 2019
(San Antonio), virtually in 2021, and 2023 (San Diego) with great international
responses. The symposium grew to two full days (four sessions) since 2017. We
plan on continuing this direction with at least a four-session symposium.
Attendance has been growing with regularly 20-30 people in attendance and
sometimes upwards of 50 for selected invited talks.
Composite materials are of growing interest for nuclear fusion and fission due
to their combined excellent physical and mechanical properties that are
compatible with extreme radiation and high temperature environments. With the
development of next-generation fission reactors and fusion power, materials
that can withstand higher neutron flux/thermal load/thermal mechanical stresses
and more aggressive environments in terms of oxidation, corrosion/erosion, and
tolerance to transmutation elements are required. This requirement makes it
necessary to (i) understand the operational limits and degradation mechanisms
of existing composite materials and (ii) develop and qualify new materials
designs. There is a strong overlap in materials research between fission and
fusion in terms materials design, processing, characterization, and modelling.
This symposium aims to bring scientists and engineers together to share ideas
and so join the effort in both fields at an international level for the
development of these crucial composite materials and to enable collaborations
across groups and countries. The design/processing/modelling/joining of the
following materials, as well as their physical/mechanical characterization
using ex situ and/or in situ techniques, are encouraged:
* Design, processing, and joining of composites for advanced fission and fusion
reactors
* Modeling over multiple length scales
* Material physical and mechanical properties characterization using ex-situ
and in-situ techniques
* Irradiation effects on materials properties and performance
* Chemical compatability reactor relevant environments
* Hydrogen transport and trapping
* Composite materials systems can include (but are not limited to):
* Graphite/carbon-based composites
* Ceramic-based composites
* Metal-matrix composites
* Composite nuclear fuels and claddings
This symposium features novel methods and new discoveries for understanding all
aspects of material fatigue. It brings together scientists and engineers from
all over the world to present their latest work on current issues in:
characterizing and simulating fatigue damage; identifying microstructural weak
links; enhancing fatigue strength and resistance; reporting on quantitative
relationships among processing, microstructure, environment, and fatigue
properties; fatigue in non-metallic materials; and providing methods to perform
life predictions. This symposium further provides a platform for fostering new
ideas about fatigue at multiple scales and in multiple environments,
numerically, theoretically, and experimentally.
The symposium organizers plan to build on the highly successful 2023 and
well-attended 2024 symposia by expanding our new topical area of non-metallic
fatigue while maintaining support fatigue topics relevant to academic and
industry research across metallic materials systems.
The proposed 2025 TMS symposium will be provisionally organized into seven
topical areas, roughly one per session. One of the sessions, related to
microstructure-based fatigue studies on additive-manufactured materials, will
be jointly organized with the AM Fatigue & Fracture symposium to prevent
overlapping topics at the TMS2025 meeting. The proposed sessions will be
carried out over three full days. Throughout the seven sessions, there will be
an estimated 60 oral presentations, with 3-5 of those being invited/keynote
presentations on relevant topics. Researchers who achieved new findings in
fundamental and industrial fatigue topics will be given the opportunity to
provide an invited talk. Additionally, a poster session will be held to
supplement the oral presentations and to encourage student involvement.
Previous FIM symposia have declined to publish extended articles, although we
will continue to gauge interest at the meeting. Topics of interest may include
(but are not limited to):
Predictive methods for fatigue properties. For instance, digital twin
approaches; data-driven, data-centric and high-throughput methods; multiscale
modeling approaches.
Advanced experimental characterization of microstructurally driven fatigue
behavior. For instance, emerging characterization methods; multi-modal,
correlative and 3D measurements.
Fatigue deformation processes. For instance, damage initiation, crack
propagation, and plastic localization.
Fatigue properties in extreme environments. For instance, Fatigue properties of
novel alloys for extreme environments; fatigue properties at high or cryogenic
temperatures; very/ultra-high cycle fatigue.
Fatigue of non-metallic materials. For example, carbon fiber composites,
cementitious and construction materials, ceramics, semiconductor materials up
to full chips and packaging, and polymeric materials systems, including resins
and other 3D printed polymers.
Fatigue studies and design under the
process-(micro)structure-properties-performance paradigm
Microstructure-based fatigue studies on additive-manufactured materials
(Coordinated joint session with Additive Manufacturing Fatigue and Fracture:
Towards Rapid Qualification Symposium)
The focus of this symposium is to discuss current research and key developments
in theory, computational and experimental methods to study and predict the
mechanical properties of materials in application-orientated environments.
These environments may include, but are not limited to high mechanical loads,
cryogenic (or high) temperatures, electrical and magnetic field, radiation,
corrosion and oxidation. In-situ mechanical testing using SEM, TEM, AFM, Raman,
synchrotron, X-ray, IR, and FTIR observation techniques are becoming
increasingly popular for studying the material response during processing or
under external loads across time and length scales. At the same time,
significant progress has been made in the development of high fidelity models
to analyze (or validate hypotheses of) the behavior of materials at different
spatial and temporal scales. The intent of the symposium is to provide a forum
for researchers from national laboratories, academia, and industry to discuss
research progresses in the area of in operando and/or in-situ mechanical
testing across time and length scales, advances in computational approaches and
most importantly, integration of experiments and modeling to accelerate the
development and acceptance of innovative materials and testing techniques.
Topics include:
Development of instruments and experimental methodology for in-situ studies of
material responses in advanced manufacturing and deformation processes.
Imaging, analytical and modeling techniques to correlate microstructure
(including dislocations, crystallographic orientations, precipitates, phases),
processing defects, and strain field with mechanical properties.
Microstructural observations using in-situ techniques across length scales.
Experimental characterization and multiscale modeling of deformation of
high-temperature materials, high-strength materials, thin films, low-dimension
nanostructures, and interfaces.
Uncertainty quantification and quantitative validation of computational models.
We are planning to have a joint session with the symposium entitled, Advanced
Real Time Imaging. Respective abstracts will be selected to include in the
joint session.
Fuel and fuel-cladding interaction constitute the key to understanding fuel
performance. The combined effects of microstructural evolution and chemical
change cause loss of performance in various forms such as embrittlement,
deformation, phase instability, etc., which need to be well understood to
enable materials evaluation and prediction in normal and accident scenarios.
The designs of current and next-generation reactors are varied. Types of fuels
include ceramic, metal, and composite fuels, such as UO2-, UN-, U3Si2-, U-Zr-,
U-Mo-based, and TRISO. There are also multiple types of cladding materials in
use or under consideration, e.g., Zircaloy, stainless steels, SiC/SiC
composites, ODS, HEA concepts, and cladding coatings. In particular, the
confounding factors from chemically active fission products (lanthanides,
tellurium, etc.) and impurities (oxygen, carbon, etc.) can complicate the fuel
performance analysis, due to changes in fuel and fuel-cladding interactions.
Meanwhile, the rapid progress of advanced reactor technologies in the industry
underscores the urgent need to expedite the development and qualification of
nuclear fuels. This symposium aims to bring together experimental and
computational investigations that assist in understanding the microstructural,
mechanical, and chemical changes in solid fuels and fuel-cladding interfaces.
Both the synergistic and separate effects of involved physical processes, with
fresh or certain burn-up or surrogate fuels, are of interest. This symposium
also calls for research on fuel performance modeling using multi-scale and
multi-physics methods. Studies of advanced fuel types and cladding concepts are
strongly encouraged.
The topics of interest include experimental and modeling efforts in the
following aspects, but not limited to:
• Evolution of defects, microstructure, and phase in fuels or fuel surrogates
• Impact of impurities on microstructure and phase transformation of fuels or
fuel surrogates
• Behaviors of fission products in fuels and/or cladding
• Development of claddings for advanced reactors
• Fuel-cladding mechanical and chemical interactions
• Accelerating fuel development and qualification via advanced
characterization, multi-scale simulation, machine learning, and other
techniques
Applications in critical fields like nuclear, aerospace, and defense often
require operation in harsh conditions, characterized by extreme temperatures,
intense mechanical stress, rapid strain-rate deformation, corrosive
atmospheres, and heavy irradiation. These severe conditions present formidable
challenges to the materials used. Nanostructured materials have emerged as a
promising solution, offering exceptional properties such as high mechanical
strength and superior resistance to irradiation. Their enhanced characteristics
make them promising candidates for use in these demanding environments. This
classification encompasses ultrafine-grained and nanocrystalline materials,
along with nanocomposites, including nanolaminates, and
nanoparticle/nanoprecipitation-strengthened materials. However, these materials
face challenges due to a tendency towards coarsening or compound formation,
driven by the high density of interfaces within them. Thus, it's crucial to
develop methods to stabilize these nanostructures.
This symposium aims to deepen our understanding of how nanostructured metallic,
ceramic, and composite materials behave under extreme conditions. We welcome
abstracts on a range of topics related to nanostructured materials, although
our interest is not limited to these areas.
• Materials response in high temperature environment
• Materials response under high or ultrahigh mechanical load/pressure
• Materials response under high strain-rate deformation
• Irradiation-induced microstructure evolution
• Evolution of mechanical and physical properties under extreme conditions
• Corrosion (and/or erosion) resistant nanomaterials and coatings
• Stress corrosion cracking of nanomaterials
• In-situ characterization of materials response in harsh environments
• Response in simultaneous and coupled multiple extreme environments
• Strategies for stabilizing nanostructure in extreme environments
• Theory and computational modeling of defect generation and interactions with
interfaces under harsh environment
• Methodological development of modeling tools for materials response in
extreme environments
Quantification and correlation of microstructural data to material properties
and process variables are key to the design of novel materials and optimization
of advanced manufacturing processes. The investigation of the evolution of
microstructural features (size, morphology, and chemistry) across different
length and time scales in novel material systems and materials subject to
advanced manufacturing processes demand the need for a thorough multiscale
characterization approach, and typically results in large datasets. Recent
developments in high-throughput and autonomous experimental approaches combined
with advances in instrumentation, computational capabilities and analysis
software have compounded the challenge of curating these large datasets. There
is an imminent need for development of novel approaches/strategies to extract
high quality and actionable microstructural information from these datasets in
a rapid and efficient manner. This symposium seeks to bring researchers from
industry and academia alike interested in discussing these novel strategies on
data obtained from a single or a combination of techniques, which include -
optical microscopy (OM), scanning electron microscopy (SEM),
scanning/transmission electron microscopy (S/TEM), neutron and synchrotron
x-ray-based techniques, atom probe tomography (APT), and x-ray micro-computed
tomography (XCT).
Topics include, but are not limited to -
• High-throughput property or microstructural characterization methodologies
that enable rapid discovery and/or improved design of novel material systems.
• Machine learning and AI guided real-time or post facto reduction of
high-volume datasets acquired during in situ characterization studies of
microstructure evolution.
• Challenges and opportunities related to curation, handling, access and
storage of metadata/data from large characterization datasets and the adherence
to FAIR data principles.
• Acceleration of feature extraction and quantification from large imaging
(OIM, SEM, EBSD, S/TEM, radiography, tomography) spectroscopy and/or
diffraction-based datasets through computer vision and/or machine learning
workflows/packages.
• Workflows for on-the-fly data extraction and feedback for advanced
manufacturing routes using in situ monitoring techniques.
Recent advances in fabrication enable the local control of microstructures,
compositions, and phases across various length scales in a monolithic material.
This is particularly relevant for extreme conditions – such as those found in
the energy, transportation, and space sectors – where materials are subject to
complex thermomechanical loading and environmental degradation. Desired
site-specific material properties can now be achieved through advances in
manufacturing, allowing graded compositions and/or microstructures across one
or more spatial dimensions. However, challenges persist in understanding the
formation and evolution of metastable interfaces during far-from-equilibrium
processing, making it difficult to identify the relationships between
processing, microstructures, and local properties. Before these materials can
be implemented, they must overcome difficulties in controlling manufacturing
pathways, harnessing nano- to mesoscale interfaces, adapting characterization
techniques, and predicting behavior a priori. A mechanistic understanding of
the design, fabrication, and performance of interface evolution is crucial for
developing the next generation of engineering materials. These novel material
systems redefine our perception of the relationships between processing,
microstructures, and properties, necessitating the exploration of
high-throughput methods to accelerate our understanding.
This symposium will bring together worldwide researchers who are pioneering
spatially tailored material design, synthesis, characterization, and
optimization of location-specific properties. This proposed 2025 TMS symposium
will be organized into four sessions, conducted over two full days.
Additionally, a poster session will be held to supplement oral presentations
and encourage student involvement. Specific topics of interest may include, but
are not limited to:
• Processing methods, including thin films, spark plasma sintering, additive
manufacturing, thermal spray, etc.
• Accelerated material discovery, design space mapping, and rapid
identification of processing-structure-property relationships
• Understanding nano-, micro-, and mesoscale interface formation and evolution,
including new methods and techniques for high-throughput characterization
• Mechanical behavior and environmental degradation of spatially tailored
interfaces under extremes
• Computational and experimental design of functionally graded materials
This symposium represents a new endeavor at TMS, addressing the growing
research in areas like functionally graded materials, additive manufacturing,
and rapid material characterization and discovery. What sets it apart from
other symposia on these general topics is its concentrated focus on the
intricate relationships between processing, structure, and properties specific
to functionally graded materials. Our goal is to enrich symposia like the
“Functionally Graded Materials, Coatings and Claddings: Toward Microstructure
and Property Control” symposium by endorsing presentations that deepen the
fundamental comprehension of these relationships in spatially graded materials.
Nuclear materials research is continuously evolving within an environment of
rapidly shifting socio-political, economic, and environmental policies and
priorities, as well as in response to research advances across the broader
materials science community. This symposium captures emergent topics to
facilitate deep and timely discussions that will elevate the impact and
visibility of these topics, and build research momentum in these areas. For
TMS 2025, three emerging topics are identified:
Lessons Learned:
Many journal publications highlight the outcome of extensive and expensive
irradiation campaigns to examine material properties or fundamental science
information, but rarely address outcomes that do not paint the outcome in a
positive manner. Presentations are sought that address unforeseen circumstances
that interrupted or negated the scientific method when studying issues related
to materials performance in extreme environments. General studies for nuclear
materials that highlight what did not work as intended and the understanding
gained on why the study did not work are strongly encouraged. Examples include:
• Artefacts generated during sample preparation or experimentation
• The role of non-disclosed impurities or processing on performance
• Impacts of non-ideal specimen geometries on thermal or mechanical performance
Radiation Effects in Non-Energy Systems:
In addition to traditional reactor improvements, advancements in nuclear
materials science have introduced capabilities in industrial, transportation,
and material characterization applications. Many of these critical advancements
have not previously been explored in nuclear-centric symposia as they do not
fit the traditional mold of nuclear materials science. This mini-symposium
seeks abstracts concerning, but not limited to, the following:
• Nuclear fission/fusion used for non-power generation applications such as
industrial heat, thermal propulsion, and isotope production
• Novel applications of nuclear waste and byproducts
• Characterization of non-reactor nuclear materials, such as components of
spallation neutron sources or high energy beamlines
Coupled Irradiation-Mechanical Extremes:
Structural materials in reactor environments experience an extreme combination
of radiation, high temperature, and stress. However, most conventional
irradiation experiments fail to investigate the effect of stress on
microstructural evolution. Simultaneous irradiation and loading significantly
affects mechanical behavior, from accelerating creep deformation to increasing
fatigue lifetimes, yet remains a critically under-explored phenomenon in the
field of nuclear materials science. This mini-symposium invites abstracts
investigating but not limited to:
• Novel testing methods to apply stress/strain during irradiation
• Irradiation creep mechanisms in metals and ceramics
• Irradiation fatigue phenomena in transient nuclear environments
Advanced nuclear reactor designs will play a critical role in meeting the
ever-increasing demand for carbon-free energy worldwide. Compared to light
water reactors (LWRs), the proposed advanced nuclear energy systems present an
exceptionally harsh environment for the structural materials due to a
combination of elevated temperature, increased radiation damage, extended
service time, and more corrosive coolants. Furthermore, the growing interest in
demonstrating advanced reactor designs requires the qualification process of
structural materials to be accelerated. All these challenges must be tackled in
order to realize the desired safety, efficiency, and economics of future
nuclear reactors. Meanwhile, rapid progress in other emerging fields, such as
additive manufacturing, high-throughput testing and simulation, multiscale
modeling, and data analytics provide new avenues to addressing these challenges
in structural materials for advanced reactors. This symposium aims to gather
research on metallic structural materials, which can be the evaluation of
existing material systems under new conditions or the design of advanced
structural materials. Both experimental and computational work are welcome.
Abstracts are solicited in, but not limited to, the following areas:
• Novel structural material concepts for enhanced radiation tolerance
• New manufacturing processes (e.g., additive manufacturing)
• High-throughput testing and characterization of materials for nuclear
applications
• Multiscale modeling and simulation
• High-throughput simulation and machine learning
• Corrosion in non-LWR and accidental conditions
• Microstructural evolution under extreme environments
Uncertainty Quantification is the science of assessing what is known and not
known in a given analysis. It provides the analysts the realm of variation in
the analytical response or solution given that input parameters may not be well
characterized. Aside from understanding the plausible variation in the
analytical responses, it also plays an important role in decision analytics.
The scope for this symposium includes examples of applying Uncertainty
Quantification methods to Material Science and Engineering analyses. It
includes any of the following topics. Methods to quantify input parameter
measurement uncertainty. Using Sensitivity Analysis to identify input
parameters which have the greatest impact on the responses of interest. Model
Calibration methods and results. Assessing model form uncertainty. Using
Bayesian methods to quantify uncertainties. How quantifying uncertainties aides
in decision making process.
The rapidly evolving field of additive manufacturing (AM) features the constant
development of new manufacturing technologies and materials and calls for the
most advanced characterization tools to enable process monitoring and control
and understand the transient microstructural development of AM materials.
Facility-based X-ray and neutron techniques and in-house advanced
characterization techniques have played a vital role in the research and
development of AM technologies. This symposium aims to bring together
scientists, engineers, and industrial professionals in the scattering, imaging,
and advanced characterization community and the additive manufacturing
community to discuss these technique’s latest development and applications in
AM and to discuss potential future directions and foster collaborations. We
especially welcome abstracts addressing industrial applications and industrial
perspectives on characterization needs.
This symposium will feature two main themes.
The first theme will feature a wide range of presentations and discussions on
using facility-based X-ray and neutron scattering, imaging, and spectroscopy
methods to understand AM processing at different time and length scales. We
welcome abstracts in areas including, but not limited to:
1. Time-resolved imaging and diffraction of the AM process
2. Structure and microstructure evolution during the build and post-build
treatments
3. Residual stress measurements and their model validation
4. X-ray fluorescence and absorption spectroscopy measurements for AM
materials’ chemical composition analysis
5. Neutron diffraction and small angle neutron scattering measurements to probe
the AM materials’ internal microstructure
6. Spatially resolved measurements at different length scales, including
microdiffraction and microtomography
7. In situ characterization of AM material response under thermo-mechanical
loadings, including quasi-static, high rate, and cyclic loading
8. Model validation with synchrotron and neutron data, including
machine-learning development
The second theme emphasizes in situ characterization and diagnostics using
laboratory-scale techniques. Abstracts are requested in, but not limited to,
the following areas:
1. Advancement of existing and emerging in situ process monitoring and process
control techniques to reveal process phenomena, detect material defects, and
control process variation
2. Identification and understanding of the formation of inherent defects and
process anomalies during fabrication from laboratory-scale research to
industrial-scale implementation, including those using machine learning
methods.
3. High deposition rate AM processes focusing on electron-beam powder bed
fusion and powder/wire-based DED processes.
Real time observations can provide important information needed to understand
materials behavior, as these techniques can provide temporal and spatial
insights free from artifacts otherwise induced from conventional experimental
techniques. Traditional and emerging advanced imaging techniques, which may be
optical or non-optical, would allow such observations. Methods may be enhanced
with capabilities that enable heating and cooling, controlled atmospheres, and
application of stresses; and can be used to generate real time thermodynamic
and kinetic data needed to study a variety of materials and processes. This
symposium encompasses a broad range of materials science topics enabling
cross-cutting opportunities for multiple disciplines (biomaterials, energy
materials, functional materials, structural materials, etc.) while topics will
be separately categorized in the technical program. Presentations are solicited
on the application of these methods to materials science and industrial
processes, as well as on development of such techniques.
Topics include, but not limited to:
• Studies using real time optical (e.g., visible light, white light, laser, IR,
and UV) and non-optical (e.g., scanning probe, electron, and ultrasound)
imaging techniques
• Researches using in-situ, in-operando, in-vitro, and in-vivo observation
imaging techniques, such as thermal imaging furnace and other real time imaging
methods
• Confocal techniques, including fluorescence and reflection types, which may
be equipped with capabilities such as heating/cooling chambers, gas chambers,
mechanical testing, Raman spectroscope, mass spectrometry, and FTIR
• Microscopic or telescopic imaging methods include hot thermocouple,
resistance heating, and sessile drop techniques used for high temperature
phenomena.
• Thermodynamic and kinetic data from these techniques, useful for phase
diagram constructions, oxidation/corrosion modeling, phase formation kinetics
studies, etc.
• Work using high speed and slow speed cameras
• Materials used in manufacturing real time imaging devices
• Novel technologies and methodologies for emerging imaging devices
The symposium plans the following joint sessions with:
• The Mechanical Response of Materials Investigated through Novel In-situ
Experiments and Modeling symposium
Respective papers may participate in part of the dedicated joint session.
This symposium features novel methods and new discoveries for understanding all
aspects of material fatigue. It brings together scientists and engineers from
all over the world to present their latest work on current issues in:
characterizing and simulating fatigue damage; identifying microstructural weak
links; enhancing fatigue strength and resistance; reporting on quantitative
relationships among processing, microstructure, environment, and fatigue
properties; fatigue in non-metallic materials; and providing methods to perform
life predictions. This symposium further provides a platform for fostering new
ideas about fatigue at multiple scales and in multiple environments,
numerically, theoretically, and experimentally.
The symposium organizers plan to build on a highly successful 2023 symposium by
introducing a new topical area, while continuing to support fatigue topics
relevant to academic and industry research.
The proposed TMS2024 symposium will be provisionally organized into seven
sessions. One of the sessions, related to microstructure-based fatigue studies
on additive-manufactured materials, will be jointly organized with the AM
Fatigue & Fracture symposium to prevent overlapping topics at the TMS2024
meeting. The proposed sessions will be carried out over three full days.
Throughout the seven sessions, there will be an estimated 60 oral
presentations, with 3-5 of those being keynote presentations on relevant
topics. Researchers who achieved new findings in fundamental and industrial
fatigue topics will be given the opportunity to provide an invited talk.
Additionally, a poster session will be held to supplement the oral
presentations and to encourage student involvement. Prizes for best posters

approaches; data-driven, data-centric and high-throughput methods; multiscale
modeling approaches.

behavior. For instance, emerging characterization methods; multi-modal,
correlative and 3D measurements.

propagation, and plastic localization.

novel alloys for extreme environments; fatigue properties at high or cryogenic
temperature; very/ultra high cycle fatigue.
Fatigue of non-metallic materials. For example, carbon fiber composites,
cementitious and construction materials, ceramics, semiconductor materials up
to full chips and packaging, and polymeric materials systems including resins
and other 3D printed polymers.

process-(micro)structure-properties-performance paradigm
Microstructure-based fatigue studies on additive-manufactured materials
(Coordinated joint session with Additive Manufacturing Fatigue and Fracture:
Towards Rapid Qualification Symposium)
Irradiation testing is integral to the development and acceptance of materials
and components intended for radiation environments. Irradiation testing
addresses a broad array of concerns ranging from the validation of models
describing irradiated material behavior to providing proof-of-concept
information to justify further development by industry or acceptance by
regulatory authorities. Nuclear energy production frequently drives the need
for developing materials with enhanced irradiation performance. Current
material development efforts include those intended for established reactor
designs as well as those being considered for use in either fusion or advanced
reactor concepts. Outside the reactor, additional structures, such as those in
spent fuel pools and storage casks, must also withstand the challenges posed by
long-term exposure to radiation during subsequent spent fuel handling, storage,
and disposal. Beyond energy production, irradiation testing can also help
develop and refine isotope production processes as well as shielding
requirements. These efforts support a wide array of applications ranging from
medical diagnostics and scientific research to enhancing worker safety and
prolonging space exploration missions, respectively. Irradiation testing is
clearly a critical aspect of material development and a wide array of test
capabilities are required. The
aim of this symposium is to highlight facilities with irradiation testing
capabilities that enable data collection from materials exposed to neutron,
proton, ion, or gamma irradiation. Topics of interest for this symposium
include irradiation vehicle design, in-situ monitoring and control, irradiation
facility capabilities, experimental design, and post-irradiation examination
capabilities. Test vehicle designs used to support drop-in or instrumented lead
experiments in materials research reactors are of interest as well as the
experimental configurations used to facilitate beamline irradiations. Active
and passive methods of monitoring and controlling key parameters, such as
temperature and flux, are also interest. Finally, methods of obtaining data
from experiments either during irradiation (e.g., in-situ data collection) or
from post-irradiation examination are also of interest. This symposium is
intended to bring together national laboratory, university, and nuclear
industry researchers from around the world to discuss the current capabilities
and challenges associated with the design and execution of irradiation
experiments.
Data-driven machine learning methods are becoming increasingly useful to
accelerate materials discovery and qualification for nuclear applications. The
investigation of the association between variables such as structure and
performance is always essential in developing strong materials for advanced
reactors. However, experiments can be very costly and lengthy considering the
reactor environments. Similarly, materials modeling can also face critiques in
mode inaccuracy and inefficiency in typical multiscale frameworks. Therefore,
how to smartly incorporate the modern development of artificial intelligence
(AI) in nuclear materials study will be of strategic significance to accelerate
nuclear materials investigation and unlock far more useful materials than
traditional Edisonian methods for optimization within a high-dimension
parametric space.
Recently, increasing work in the nuclear materials community has indicated the
efficacy of this powerful tool in improving the accuracy and efficiency of
modeling tools, and prediction of radiation effects such as void swelling and
embrittlement based on experimental data. Indeed, more integrations of AI and
nuclear materials investigation are widely open for exploration, e.g., guiding
the material design and synthesis, multi-parameter optimization, and modeling
linear or non-linear relations among physical quantities. In this symposium, we
hope to bring together the research in nuclear materials taking advantage of
materials informatics.
The topics of interest include both experimental and modeling efforts in the
investigation of nuclear materials that involve the application of machine
learning methods, such as (not limited to):
• Fundamental defects properties
• Microstructural evolution
• Radiation effects (swelling, hardening, embrittlement, etc)
• Mechanical/Chemical interactions
• Manufacturing and characterization technologies
The focus of this symposium is to discuss current research and key developments
in theory, computational and experimental methods to study and predict the
mechanical properties of materials in application-orientated environments.
These environments may include, but are not limited to high temperature,
cryogenic temperature, electrical and magnetic field, gas, radiation, chemical,
pressure extremes, and humidity. In-situ mechanical testing using SEM, TEM,
AFM, Raman, synchrotron, X-ray, IR, and FTIR observation techniques during
testing are becoming increasingly popular for studying mechanical behavior of
materials. Many such techniques have been developed to probe material response
to stimuli across nano- to macro-length scales. At the same time, significant
progress has been made in the development of high fidelity models to analyze
the behavior of materials at different spatial and temporal scales. The intent
of the symposium is to provide a forum for researchers from national
laboratories, academia, and industry to discuss research progress in the area
of in operando and/or in-situ mechanical testing at small length scales,
advances in computational approaches and most importantly, integration of
experiments and modeling to accelerate the development and acceptance of
innovative materials and testing techniques.
Topics include:
Development of instruments and experimental methodology for in-situ techniques
and/or testing at non-ambient temperatures and/or environments.
Imaging, analytical and modeling techniques to correlate microstructure,
defects, crystal orientation, and strain field with mechanical properties.
Microstructural observations using in-situ techniques across length scales.
Experimental characterization and multiscale modeling of deformation of
high-temperature materials, high-strength materials, thin films, 1D, 2D, and
other low-dimension nanostructures, and interfaces.
Uncertainty quantification and quantitative validation of computational models.
We are planning to have a joint session with the symposium entitled, Advanced
Real Time Imaging. Respective papers will be selected to include in the joint
session.
Many critically important applications (such as nuclear, aerospace and defense)
involve extreme environments where high temperature, high mechanical stress,
high strain-rate deformation, corrosive atmosphere and intense irradiation are
present. Such extreme environments pose significant challenges to the materials
being used. Nanostructured materials, including ultrafine-grained and
nanocrystalline materials, nanotwinned metals and alloys, nanolayered
materials, nanoparticles or nanoprecipitates strengthened materials, etc., have
exhibited many excellent properties like high mechanical strength and superior
irradiation resistance and attracted a lot of research. Their improved
properties make them promising candidates for applications in extreme
environments. In addition, from the aspect of fundamental research,
nanostructured materials in harsh environment offer exciting opportunities to
investigate how microstructures respond to the environment and how this
eventually affects the mechanical and physical properties. However, there are
strong driving forces for irreversible processes such as coarsening or compound
formation in nanostructured materials due to the existing high density of
interfaces in them. Therefore, strategies need to be developed for the
stabilization of the nanostructures.
This symposium will focus on understanding the unique aspects of the
response of nanostructured metallic, ceramic and composite materials in extreme
environments. Abstracts are solicited in, but not necessarily limited to, the
following areas with respect to nanostructured materials:
• Response in high temperature environment
• Response under high or ultrahigh mechanical load/pressure
• Response under high strain-rate deformation
• Irradiation response and defect generation and migration, as well as
microstructure evolution during irradiation
• Evolution of mechanical and physical properties under extreme conditions
• Corrosion (and/or erosion) resistant nanomaterials and coatings
• Stress corrosion cracking of nanomaterials
• In-situ characterization of materials response in harsh environments
• Response in simultaneous and coupled multiple extreme environments
• Diffusive and displacive phase transformations in harsh environments
• Strategies for stabilizing nanostructure in extreme environments
• Theory and computational modeling of defect generation and interactions with
interfaces under harsh environment
• Methodological development of modeling tools for materials response in
extreme environments
Quantification and correlation of microstructural data to material properties
and process variables are key to the design of novel materials and optimization
of advanced manufacturing processes. The investigation of the evolution of
microstructural features (size, morphology, and chemistry) across different
length and time scales in novel material systems and materials subject to
advanced manufacturing processes demand the need for a thorough multiscale
characterization approach, and typically results in large datasets. Recent
developments in high-throughput and autonomous experimental approaches combined
with advances in instrumentation, computational capabilities and analysis
software have compounded the challenge of curating these large datasets. There
is an imminent need for development of novel approaches/strategies to extract
high quality and actionable microstructural information from these datasets in
a rapid and efficient manner. This symposium seeks to bring researchers from
industry and academia alike interested in discussing these novel strategies on
data obtained from a single or a combination of techniques, which include -
optical microscopy (OM), scanning electron microscopy (SEM),
scanning/transmission electron microscopy (S/TEM), neutron and synchrotron
x-ray-based techniques, atom probe tomography (APT), and x-ray micro-computed
tomography (XCT).
Topics include, but are not limited to:
* Advances in methods for feature extraction and quantification from large
imaging datasets (OM, SEM, S/TEM, radiography, tomography) and their
accelerated analysis through computer vision and/or machine learning packages.
* Novel developments in hardware enabling rapid acquisition of microstructural
data for high-throughput characterization techniques and analysis workflows for
autonomous characterization experiments.
* Utilization of machine learning enabled pipelines for fast reduction and
quantification of microstructural information from large imaging, spectroscopy
and/or diffraction-based datasets.
* Techniques for tracking and analysis of microstructural evolution in real
time or post-facto from in situ characterization datasets
�* Workflows for on-the-fly data extraction and feedback for advanced
manufacturing routes using in situ monitoring techniques - e.g.- IR
thermography, back-scatter electron imaging in additive manufacturing machines.
* Challenges and opportunities related to curation, handling, access and
storage of metadata/data from large characterization datasets and the adherence
to FAIR data principles.
This symposium focuses on the use of Electron Backscattered Diffraction (EBSD)
in the Scanning Electron Microscope (SEM) but contributions on related SEM
based techniques are encouraged as well including: Transmission Kikuchi
Diffraction (TKD), Electron Channeling Patterns (ECP) and Electron Channeling
Contrast Imaging (ECCI). We invite contributions in the following areas:
• Advances in theory, modeling, indexing and interpretation of diffraction
patterns.
• Novel analysis and quantitative metrics of EBSD data
• Advances in detector systems, including direct electron detection
• EBSD, TKD, and/or ECP/ECCI applications in Materials Science
• EBSD, TKD, and/or ECP/ECCI applications in Geology
• Open source software related to EBSD, TKD, ECP, ECCI
This symposium will provide a platform for researchers working on the
state-of-the-art of multiscale modeling of materials, microstructural
characterization, and small-scale mechanical testing to understand the
mechanical behavior of crystalline metals.
Background and Rationale: The mechanical behavior of crystalline metals
strongly depends on microstructure and the evolution of microstructure at
different length scales. Examples include changes in crystallography, defect
content and distribution, grain morphology, interfaces, and texture. The
success behind the development of multiscale predictive model relies on finding
and exploiting the synergies between modeling and experiments. In recent years
intense efforts have been dedicated to advancing atomistic, micro, meso and
macro-scale simulations tools and bridging them to understand the
structure-property relationship. Achieving this goal requires a strong
connection between models and experimental characterization techniques at
different length scales. This symposium aims to encourage
scientists/researchers from diverse areas of materials science and engineering
to present recent achievements, identify challenges in developing multiscale
material models from the atomic scale to the macro scale, and discuss
connections with advanced experimental techniques.
The subject areas of the symposium include, but are not limited to:
1. Structural, functional and nuclear materials
2. Dislocations, deformation twins, phase transformation and recrystallization
3. Atomistic modeling
4. Dislocation dynamics and phase field modeling
5. Crystal plasticity models
6. Advanced X-ray and neutron diffraction techniques
7. Advanced microscopy techniques including HR-(S)TEM, HR-EBSD, PED and in-situ
TEM and SEM
8. Emphasis on integrating experiments with modeling for guidance/validation
9. Experimentally aided Multi-scale Material Modeling
Objective: This symposium will provide a venue for presentations featuring the
use of advanced characterization techniques in all classes of materials to
quantify and model deformation mechanisms.
Background and Rationale: Advances in characterization technology have greatly
improved our ability to quantify deformation mechanisms such as dislocation
motion, twinning, and stress-induced phase transformations, and the
microstructural changes accompanying deformation such as texture evolution,
grain morphology changes, dislocation accumulation and localized strain. A
variety of relatively new techniques are being applied to both structural and
functional materials. In combination with modeling, these techniques improve
our understanding of deformation and failure during material processing/forming
and under normal or extreme conditions in service. In situ techniques,
especially, are providing an enhanced understanding of individual mechanisms,
their interactions, and the direct validation of simulations from computational
materials science models. This gathering offers a venue to discuss and share
new advances in current techniques or new technique development or in pairing
with algorithms or simulations as they apply to deformation behavior.
Areas of interest include, but are not limited to:
(1) Improving the understanding of deformation mechanisms in structural or
functional materials – elasticity, dislocation plasticity, mechanically-induced
twinning or phase transformations, damage and fracture
(2) Advances in characterization techniques: X-ray-based techniques,
electron-based techniques (including HR-(S)TEM, EBSD, HR-EBSD, ECCI, PED),
scanning probe microscopy techniques, and others – in particular in-situ
(3) Advances in materials deformation modeling– with specific emphasis on the
integration with advanced characterization techniques
Real time observations can provide important information needed to understand
materials behavior, as these techniques can provide temporal and spatial
insights free from artifacts otherwise induced from conventional experimental
techniques. Traditional and emerging advanced imaging techniques, which may be
optical or non-optical, would allow such observations. Methods may be enhanced
with capabilities that enable heating and cooling, controlled atmospheres, and
application of stresses; and can be used to generate real time thermodynamic
and kinetic data needed to study a variety of materials and processes. This
symposium encompasses a broad range of materials science topics enabling
cross-cutting opportunities for multiple disciplines (biomaterials, energy
materials, functional materials, structural materials, etc.) while topics will
be separately categorized in the technical program. Presentations are solicited
on the application of these methods to materials science and industrial
processes, as well as on development of such techniques.
Topics include, but not limited to:
• Studies using real time optical (e.g., visible light, white light, laser, IR,
and UV) and non-optical (e.g., scanning probe, electron, and ultrasound)
imaging techniques
• Researches using in-situ, in-operando, in-vitro, and in-vivo observation
imaging techniques, such as thermal imaging furnace and other real time imaging
methods
• Confocal techniques, including fluorescence and reflection types, which may
be equipped with capabilities such as heating/cooling chambers, gas chambers,
mechanical testing, Raman spectroscope, mass spectrometry, and FTIR
• Microscopic or telescopic imaging methods include hot thermocouple,
resistance heating, and sessile drop techniques used for high temperature
phenomena.
• Thermodynamic and kinetic data from these techniques, useful for phase
diagram constructions, oxidation/corrosion modeling, phase formation kinetics
studies, etc.
• Work using high speed and slow speed cameras
• Materials used in manufacturing real time imaging devices
• Novel technologies and methodologies for emerging imaging devices
The symposium plans the following joint sessions with:
• The Bio-Nano Interfaces and Engineering Applications symposium
• The Mechanical Response of Materials Investigated through Novel In-situ
Experiments and Modeling symposium
Respective papers may participate in part of the dedicated sessions.
This symposium will provide a venue for presentations regarding the use of
coherent diffraction
imaging techniques (x-ray and electron diffraction imaging, ptychography,
holography) and phase contrast imaging
techniques for high-resolution characterization in all classes of materials.
Additionally, modeling and simulation
methods that are relevant to nanoscale imaging techniques will be included.
Background and Rationale:
A high degree of spatial coherence is an attractive property in x-ray and
electron beams. Those from modern
synchrotrons and electron microscopes have enabled the development of novel
imaging methods. In some cases,
these imaging methods provide resolution beyond that achieved with optics and
can also provide remarkable
sensitivity to a variety of contrast mechanisms.
The two methods that will be the focus of this symposium are coherent
diffractive imaging (CDI) and phase contrast
imaging (PCI) with both x-rays and electrons. Both explicitly take advantage of
the coherence properties of the
incident beams. CDI has rapidly advanced in the last twenty years to allow
characterization of a broad range of
materials, including nanoparticles, strained crystals, biomaterials and cells.
PCI has been widely employed in
dynamics and engineering studies of materials, geophysics, medicine and
biology. Various techniques making use
of both x-rays and electrons have been developed that provide unique
characterization abilities such as three dimensional strain mapping and
non-destructive three-dimensional quantitative tomographic imaging.
Increasingly, materials modeling at the atomistic and continuum scales is being
used in conjunction with these
imaging techniques to enhance their capability. Such combined imaging and
modeling methods include building
experimentally informed models, which are in turn used to make predictions at
spatio-temporal scales inaccessible
to the imaging technique, and the use of deep learning algorithms trained on
synthetic data. These pre-trained deep
learning algorithms are being used to improve the quality of acquired x-ray
data, reduce experimental measurement
times and also reduce compute time required to recover 3D images from raw data.
Finally, as the new 4th generation x-ray light sources (Diffraction Limited
Storage Ring or DSLR) come online
around the world such as the ESRF in France or APS in Argonne National
Laboratory, these brilliant and coherent
x-ray sources will become increasingly important and applicable to those
wanting to understand materials behaviors
at the mesoscale to nanometer scale. Our 2023 symposium will have a special
session dedicated to imaging
experiments at these exciting new sources and their applications to materials.
Areas of interest include, but are not limited to:
(1). All x-ray based techniques including Bragg CDI, Fresnel CDI, ptychographic
CDI, propagation phase contrast
imaging, interferometry imaging, and analyzer based phase-contrast imaging
(2). All electron based techniques including ptychography and electron CDI
(3). Computational and simulation efforts with overlap in high resolution
imaging.
(4). Big data analytics and machine learning methods to accelerate data
abstraction and improve image quality
(5). All structural and functional materials systems needing high resolution
imaging
(6). Industrial applications
(7.) Development of new techniques and new sources
Composite materials are of growing interest for nuclear fusion and fission due
to their combined excellent physical and mechanical properties that are
compatible with extreme radiation and high temperature environments. With the
development of next-generation fission reactors and fusion power, materials
that can withstand higher neutron flux/thermal load/thermal mechanical stresses
and more aggressive environments in terms of oxidation, corrosion/erosion, and
tolerance to transmutation elements are required. This requirement makes it
necessary to (i) understand the operational limits and degradation mechanisms
of existing composite materials and (ii) develop and qualify new materials
designs. There is a strong overlap in materials research between fission and
fusion in terms materials design, processing, characterization, and modelling.
This symposium aims to bring scientists and engineers together to share ideas
and so join the effort in both fields at an international level for the
development of these crucial composite materials and to enable collaborations
across groups and countries. The design/processing/modelling/joining of the
following materials, as well as their physical/mechanical characterization
using ex situ and/or in situ techniques, are encouraged:
• Graphite/carbon-based composites for fission and/or fusion (e.g., nuclear
graphite, C/C, and novel designs)
• Ceramic-based composites for fusion and/or for nuclear cladding (e,g.,
SiC-SiC, C/SiC, and novel designs)
• Metal-based composites (e.g., ODS steels, components with protective single-
or bi-layer coatings including diamond on fusion components and/or Cr or Cr/Nb
on accident-tolerant fuel cladding, tungsten/tungsten composites, laminate
systems)
• TRISO fuel (e.g., particles, compacts, and FCM fuel)
Presentations on SiC-related topics will be coordinated with concurrent
symposia on ceramics to minimize overlap.
This symposium features novel methods and new discoveries for understanding all
aspects of material fatigue. It brings together scientists and engineers from
all over the world to present their latest work on current issues in:
characterizing and simulating fatigue damage; identifying microstructural weak
links; enhancing fatigue strength and resistance; reporting on quantitative
relationships among processing, microstructure, environment, and fatigue
properties; and providing methods to perform life predictions. This symposium
further provides a platform for fostering new ideas about fatigue at multiple
scales and in multiple environments, numerically, theoretically, and
experimentally.
The symposium organizers are committed to achieving excellence in 2023 by
providing a comprehensive symposium that highlights the relevant fatigue topics
to academic and industry research.
The proposed 2023 TMS symposium will be organized into six sessions. One of the
sessions, related to microstructure-based fatigue studies on
additive-manufactured materials, will be jointly organized with the AM Fatigue
& Fracture symposium to prevent overlapping topics at the TMS2023 meeting. The
proposed six sessions will be carried out over three full days. Throughout the
six sessions, there will be an estimated 50 oral presentations, with 2-4 of
those being keynote presentations on relevant topics. Researchers who achieved
new findings in fundamental and industrial fatigue topics will be given the
opportunity to provide an invited talk. Additionally, a poster session will be
held to supplement the oral presentations and to encourage student involvement.
Prizes for best posters will be awarded. A possible edited volume of extended
articles on select topics discussed in this symposium will be evaluated during
the meeting. Topics of interest may include (but are not limited to):
* Predictive methods for fatigue properties. For instance, digital twin
approaches; data-driven, data-centric and high-throughput methods; multiscale
modeling approaches.
* Advanced experimental characterization of microstructurally driven fatigue
behavior. For instance, emerging characterization methods; multi-modal,
correlative and 3D measurements.
* Fatigue deformation processes. For instance, damage initiation, crack
propagation, and plastic localization.
* Fatigue properties in extreme environments. For instance, Fatigue properties
of novel alloys for extreme environments; fatigue properties at high or
cryogenic temperature; very high cycle fatigue.
* Fatigue studies and design under the
process-(micro)structure-properties-performance paradigm.
* Microstructure-based fatigue studies on additive-manufactured Materials.
The focus of this symposium is to discuss current research and key developments
in theory, computational and experimental methods to study and predict the
mechanical properties of materials in application-orientated environments.
These environments may include, but are not limited to high temperature,
cryogenic temperature, electrical and magnetic field, gas, radiation, chemical,
pressure extremes, and humidity. In-situ mechanical testing using SEM, TEM,
AFM, Raman, synchrotron, X-ray, IR, and FTIR observation techniques during
testing are becoming increasingly popular for studying mechanical behavior of
materials. Many such techniques have been developed to probe material response
to stimuli across nano- to macro-length scales. At the same time, significant
progress has been made in the development of high fidelity models to analyze
the behavior of materials at different spatial and temporal scales. The intent
of the symposium is to provide a forum for researchers from national
laboratories, academia, and industry to discuss research progress in the area
of in operando and/or in-situ mechanical testing at small length scales,
advances in computational approaches and most importantly, integration of
experiments and modeling to accelerate the development and acceptance of
innovative materials and testing techniques.
Topics include:
• Development of instruments and experimental methodology for in-situ
techniques and/or testing at non-ambient temperatures and/or environments.
• Imaging, analytical and modeling techniques to correlate microstructure,
defects, crystal orientation, and strain field with mechanical properties.
• Microstructural observations using in-situ techniques across length scales.
• Experimental characterization and multiscale modeling of deformation of
high-temperature materials, high-strength materials, thin films, 1D, 2D, and
other low-dimension nanostructures, and interfaces.
• Uncertainty quantification and quantitative validation of computational
models.
We are planning to have a joint session with the symposium entitled, Advanced
Real Time Imaging. Respective papers will be selected to include in the joint
session.
Microstructural characterization of irradiated microstructure is the key to
building mechanistic models that predict material behavior under irradiation.
While a great knowledge has been obtained from the conventional ex situ,
post-irradiation examinations, in situ experiments using electrons, x-ray or
neutrons can provide unique information that cannot be acquired by
post-irradiation examinations. With recent advance in instrumentation,
techniques and with the integration with modeling and artificial intelligence,
there are renewed opportunities for in situ microscopy to further enhance our
understanding on the irradiation effects on materials. This symposium looks for
studies that utilize advanced methods or tools that in situ investigate the
microstructure of materials under irradiation. The scope of the symposium
includes, but not limited to:
• In situ observation of material microstructure under irradiation or
irradiated materials under influences (e.g. deformation, heating, corrosion)
using charged particles, x-ray or neutrons.
• Advanced in situ irradiation microscopy techniques
• Computer vision (CV) and machine learning (ML) applications on in situ
microscopy
• Integrating in situ irradiation experiment with modeling and simulation
• Correlation of microstructure induced by In-situ ion irradiation and neutron
irradiation
• Artifact of in situ experiments and mitigation methods.
Fuel and fuel-cladding interaction constitute the key to understanding fuel
performance. The combined effect of microstructural evolution and chemical
change cause loss of performance in various forms such as embrittlement,
deformation, phase instability, etc, which need to be well understood to enable
materials evaluation and prediction in normal and accident scenarios. The
designs of current and next-generation reactors are varied. The types of fuels
include ceramic, metal, and composite fuels, including UO2-, UN-, U3Si2-,
U-Zr-, U-Mo-based, and TRISO. There are also multiple types of cladding
materials in use/consideration, e.g., zircoloy, stainless steels, SiC/SiC
composite, ODS, HEA concepts and coating, made by various advanced
manufacturing methods. In particular, the confounding factors from chemically
active fission products (lanthanides, tellurium, etc.) and impurities (oxygen,
carbon, etc.) can complicate the fuel performance analysis, due to the changes
in fuel and fuel-cladding interaction. This symposium aims to bring together
experimental and computational investigations that assist in understanding the
microstructural, mechanical, and chemical changes in these solid fuels and
fuel-cladding interfaces. Both the synergistic and separate effects of involved
physical processes, with fresh or certain burn-up or surrogate fuels, are of
interest. Analysis of advanced fuel types and cladding concepts are strongly
encouraged. This symposium also calls for multi-scale modeling and simulations
and fuel performance modeling.
The topics of interest include experimental and modeling efforts in the
following aspects, but not limited to:
• Evolution of defects, microstructure, and phase in fuels or fuel surrogates
• Impact of impurities on microstructure and phase transformation of fuels or
fuel surrogates
• Behaviors of fission products in fuels and/or cladding
• Fuel-cladding mechanical and chemical interactions
• Advanced manufacturing and characterization technologies for nuclear fuels
Many critically important applications (such as nuclear, aerospace and defense)
involve extreme environments where high temperature, high mechanical stress,
high strain-rate deformation, corrosive atmosphere and intense irradiation are
present. Such extreme environments pose significant challenges to the materials
being used. Nanostructured materials, including ultrafine-grained and
nanocrystalline materials, nanotwinned metals and alloys, nanolayered
materials, nanoparticles or nanoprecipitates strengthened materials, etc., have
exhibited many excellent properties like high mechanical strength and superior
irradiation resistance and attracted a lot of research. Their improved
properties make them promising candidates for applications in extreme
environments. In addition, from the aspect of fundamental research,
nanostructured materials in harsh environment offer exciting opportunities to
investigate how microstructures respond to the environment and how this
eventually affects the mechanical and physical properties. However, there are
strong driving forces for irreversible processes such as coarsening or compound
formation in nanostructured materials due to the existing high density of
interfaces in them. Therefore, strategies need to be developed for the
stabilization of the nanostructures.
This symposium will focus on understanding the unique aspects of the response
of nanostructured metallic, ceramic and composite materials in extreme
environments. Abstracts are solicited in, but not necessarily limited to, the
following areas with respect to nanostructured materials:
• Response in high temperature environment
• Irradiation response and defect generation and migration, as well as
microstructure evolution during irradiation
• Evolution of mechanical and physical properties under extreme conditions
• Corrosion (and/or erosion) resistant nanomaterials and coatings
• Stress corrosion cracking of nanomaterials
• In-situ characterization of materials response in harsh environments
• Response in simultaneous and coupled multiple extreme environments
• Diffusive and displacive phase transformations in harsh environments
• Strategies for stabilizing nanostructure in extreme environments
• Theory and computational modeling of defect generation and interactions with
interfaces under harsh environment
• Methodological development of modeling tools for materials response in
extreme environments
The transient heat transfer conditions encountered in additive manufacturing
(AM) result in unusual microstructures and textures that can have different
properties from conventional wrought or cast processes. The unique
microstructure results from the combination of rapid melting and solidification
from the AM process. The directional heat transfer results in strongly textured
columnar grains, and this microstructure affects the mechanical properties of
the final part. Conventionally processed products have been considered superior
compared to AM in many of the most demanding and safety critical engineering
applications due to the heterogeneity and orientation dependency of mechanical
properties, potential for life-limiting defect content, and qualification
challenges. This limits adoption of AM parts where they could otherwise offer
an advantage, for example in weight savings or reduction in final machining.
Mechanical anisotropy results from the strong crystallographic texture in
as-fabricated AM parts, and this anisotropy can be influenced with an
optimization of the laser scanning strategy or a post fabrication heat
treatment. Because the initial microstructures from AM are different from
conventional processes, optimal heat treatment times and temperatures for AM
materials can differ from those used in conventional thermomechanical
processing. The lack of standardization between machines creates an additional
level of complexity. As a result, the qualification of materials from AM would
benefit from an accurate digital twin of the process, capable of predicting
defect probabilities and local microstructure heterogeneity. This symposium
will explore the unique thermal sequence of AM materials and their distinctive
microstructures, which affect their performance.
Contributions are sought that address microstructure development during AM from
experimental and computational perspectives, including but not limited to:
- quantitative microstructure characterization
- mechanisms of defect formation
- correlation of in-situ process monitoring data with microstructure
- defect probability predictions
- uncertainty quantification
- multiphysics simulations, both of the manufacturing process and the effects
of microstructure on performance.

Advanced nuclear reactors will play a critical role in meeting the
ever-increasing demand for carbon-free energy worldwide. Compared to light
water reactors (LWRs), the proposed advanced nuclear energy systems present an
exceptionally harsh environment for the structural materials due to a
combination of elevated temperature, increased radiation damage, extended
service time, and more corrosive coolants. Furthermore, the growing interest in
demonstrating advanced reactor designs requires the qualification process of
structural materials to be accelerated. All of these challenges must be tackled
in order to realize the desired safety, efficiency, and economics of future
nuclear reactors. Meanwhile, rapid progress in other emerging fields, such as
additive manufacturing, high-throughput testing and simulation, multiscale
modeling, and data analytics provide new avenues to addressing these challenges
in structural materials for advanced reactors. This symposium emphasizes not
only the evaluation of existing material systems under new conditions, but also
the design of advanced structural materials spanning across alloys, ceramics,
composites, etc. Both experimental and computational work are welcome.
Abstracts are solicited in, but not limited to, the following areas:
• Novel structural material concepts for enhanced radiation tolerance
• New manufacturing processes (e.g., additive manufacturing)
• High-throughput testing and characterization of materials for nuclear
applications

Additive manufacturing (AM) is beginning to realize its transformative
potential to impact many industrial sectors through performance gains, weight
savings, and rapid part customization and delivery. However, more widespread
utilization of AM technologies in critical sectors such as aerospace and
defense is still hindered by the challenges of qualification and certification
of AM parts. The main reasons for these challenges are the material and
functional complexities arising from the highly heterogeneous microstructure
across multiple length scales that are introduced during the nonequilibrium
fabrication processes. To solidify AM’s status as a new design paradigm,
continuous advancements in process control and process monitoring as well as
development and application of advanced characterization methods to measure and
quantify the interactions between material and processing parameters to better
understand and construct the material-process-structure relationship are
required.
The purpose of this symposium is to provide a forum to share, spread, and
promote exciting ideas and progress of AM materials and process
characterization using advanced synchrotron, neutron, and laboratory-scale
processing monitoring and control techniques. It has two main themes. The first
theme emphasizes characterization of AM materials using facility-based,
state-of-the-art synchrotron and neutron characterization techniques. Abstracts
are requested in, but not limited to, the following areas:
1. Time-resolved imaging and diffraction of the AM process
2. Structure and microstructure evolution during post-build heat treatment
3. Residual stress measurements and their model validation
4. Spatially resolved measurements at different length scales, including
microdiffraction and microtomography
5. Mechanical behavior characterization, including deformation, fatigue, and
fracture
6. Additive manufacturing inspired machine learning methods
The second theme emphasizes in situ characterization and diagnostics using
laboratory-scale techniques. Abstracts are requested in, but not limited to,
the following areas:
1. Advancement of existing and emerging in situ process monitoring and process
control techniques to reveal process phenomenon, detect material defects, and
control process variation.
2. Identification and understanding of the formation of inherent defects and
process anomalies during fabrication from laboratory-scale research to
industrial-scale implementation, including those using machine learning
methods.
We also welcome abstracts addressing industrial applications and industrial
perspective on characterization needs, as well as theoretical modeling and
numerical simulations that are validated by synchrotron, neutron, or
laboratory-scale in situ measurements.
Evaluating the evolution of nuclear fuel during reactor operation is essential
to foster the scientific understanding of fuel behavior. This can provide the
data needed to enhance the burn-up of current fuels, enable the use of new
accident tolerant fuel forms and metallic fuels. With this research motivation
many research facilities worldwide have developed their ability to characterize
fresh and irradiated fuels utilizing advanced electron microscopy and thermal
characterization techniques.
The application of these techniques has led to fuels being studied before and
after service providing new knowledge and ideas to enhance burnup and fuel
utilization or investigate new fuel forms. In addition, these tools have been
applied to evaluate the movement of fission products and further the
understanding of the fuel clad chemical interactions and are now ready to be
deployed in other fields of research as well.
In parallel, model development and implementation of the data generated with
advanced techniques in physics-based models for fuel performance codes is
becoming increasingly important, both for current fuel burnup extension and
advanced fuel development.
This symposium aims to take a closer look at the evolution of the
microstructure and thermo-physical properties of nuclear fuels during service,
including the interaction region between fuel and cladding. Correspondingly,
the synergy with materials modeling in advancing and understanding fuels
performance under normal and accident conditions will be considered in the
symposium.
Topics of interest include, but are not limited to:
Scanning electron microscopy characterization of nuclear fuels and its
associated techniques such as Energy dispersive spectroscopy and
Wavelength-dispersive X-ray spectroscopy and Electron backscatter diffraction
Transmission electron microscopy characterization of nuclear fuels
3D reconstructions of electron backscatter diffraction or scanning election
microscopy images of nuclear fuels
Thermo-physical property measurements of both fresh and irradiated nuclear fuels
Modeling of nuclear fuel behavior during operation
Objective: This symposium will provide a venue for presentations featuring the
use of advanced characterization techniques in all classes of materials to
quantify and model deformation mechanisms.
Background and Rationale: Advances in characterization technology have greatly
improved our ability to quantify deformation mechanisms such as dislocations,
twinning, and stress induced phase transformations, and the microstructural
changes accompanying deformation such as texture evolution, grain morphology
changes, and localized strain. A variety of relatively new techniques are
being applied to both structural and functional materials. These techniques,
in combination with modeling, are improving our understanding of deformation
and failure during material processing/forming and under normal or extreme
conditions in service. In situ techniques, especially, are providing enhanced
understanding of individual mechanisms, their interactions, and direct
validation of simulations from computational materials science models. This
gathering provides a venue to discuss and share new advances in current

techniques
(7) New characterization and in-situ technique development
Real time observations can provide important information needed to understand
materials behavior, as these techniques can provide temporal and spatial
insights free from artifacts otherwise induced from conventional experimental
techniques. Traditional and emerging advanced imaging techniques, which may be
optical or non-optical, would allow such observations. Methods may be enhanced
with capabilities that enable heating and cooling, controlled atmospheres, and
application of stresses; and can be used to generate real time thermodynamic
and kinetic data needed to study a variety of materials and processes. This
symposium encompasses a broad range of materials science topics enabling
cross-cutting opportunities for multiple disciplines (biomaterials, energy
materials, functional materials, structural materials, etc.) while topics will
be separately categorized in the technical program. Presentations are solicited
on the application of these methods to materials science and industrial
processes, as well as on development of such techniques.

This conference plans to bring together scientists and engineers who focus on
advances in synthesis and processing, atomic-scale characterization,
structure-property correlations, and modeling of novel non-equilibrium
nanostructured materials and functional thin films. The scope of the conference
includes zero-dimensional (such as nanodots), one-dimensional (nanotubes and
nanowires), two-dimensional (thin films), and three-dimensional (bulk)
nanostructures, uniquely synthesized under extreme non-equilibrium conditions.
Integration of such novel functional materials on practical substrates such as
silicon and sapphire plays a critical role in creating multifunctional
materials for next-generation systems and will be included as one of the
important areas of interest in the proposed symposium. The symposium highlights
the science of the thin film deposition methods, nonequilibrium processing
techniques (laser/electron/ion irradiations, flash sintering, and mechanical
milling, etc.), role of interfaces, and defects for fabricating such novel
non-equilibrium nanostructures and thin-film heterostructures. It focuses on
the recent discoveries of 2D materials, nanodiamonds, oxide thin films, and
nanostructures through non-equilibrium processing which stands to revolutionize
quantum computing, superhard coatings, high-temperature, and high-power
electronics, and biomedical applications.
Topics include:
• Non-equilibrium processes for the synthesis of novel nanostructures.
• Structure-properties correlations in complex oxide thin film
heterostructures.

electronics and biomedical applications.
This symposium features novel methods and new discoveries for understanding all
aspects of material fatigue. It brings together scientists and engineers from
all over the world to present their latest work on current issues in:
characterizing and simulating fatigue damage; identifying microstructural weak
links; enhancing fatigue strength and resistance; reporting on quantitative
relationships among processing, microstructure,
environment, and fatigue properties; and providing methods to perform life
predictions. This symposium further provides a platform for fostering new ideas
about fatigue at multiple scales and in multiple environments, numerically,
theoretically, and experimentally.
The proposed 2022 TMS symposium will be organized into six sessions:

The proposed six sessions will be carried out over three full days, with
morning and afternoon sessions each day. Throughout the six sessions, there
will be an estimated 50 oral presentations, with 2-4 of those being keynote
presentations. Additionally, a poster session will be held to supplement the
oral presentations and to encourage student involvement. Students may submit an
abstract for a poster presentation, an oral presentation, or both. Prizes for
best posters will be awarded. A possible edited volume of extended articles on
select topics discussed in this symposium will be evaluated during the meeting.
The focus of this symposium is to discuss current research and key developments
in theory, computational and experimental methods to study and predict the
mechanical properties of materials in application-orientated environments.
These environments may include, but are not limited to high temperature,
cryogenic temperature, electrical and magnetic field, gas, radiation, chemical,
pressure extremes, and humidity. In-situ mechanical testing using SEM, TEM,
AFM, Raman, synchrotron, X-ray, IR, and FTIR observation techniques during
testing are becoming increasingly popular for studying mechanical behavior of
materials. Many such techniques have been developed to probe material response
to stimuli across nano- to macro-length scales. At the same time, significant
progress has been made in the development of high fidelity models to analyze
the behavior of materials at different spatial and temporal scales. The intent
of the symposium is to provide a forum for researchers from national
laboratories, academia, and industry to discuss research progress in the area
of in operando and/or in-situ mechanical testing at small length scales,
advances in computational approaches and most importantly, integration of
experiments and modeling to accelerate the development and acceptance of
innovative materials and testing techniques.

other low-dimension nanostructures, and interfaces.
• Uncertainty quantification and quantitative validation of computational
models.

Nuclear energy is an essential element of a clean energy strategy, avoiding
greenhouse gas emissions of over two billion tons per year. Ceramic materials
play a critical role in nuclear energy research and applications. Nuclear
fuels, such as uranium dioxide (UO2) and mixed oxide (MOX) fuels, have been
widely used in current light water reactors (LWRs) to produce about 15% of the
electricity in the world. Silicon carbide (SiC) is a promising
accident-tolerant cladding material and is under active research studies. Some
oxide ceramics have been proposed for novel inert matrix fuels or have been
extensively studied as waste forms for the immobilization of nuclear waste.
Moreover, ceramics are under active studies for fusion reactor research. This
symposium focuses on experimental and computational studies of ceramics for
nuclear energy research and applications. Both practical reactor materials and
surrogate materials are of interest. The topics of interest include but are not
limited to: defect production and evolution; mobility, dissolution, and
precipitation of solid, volatile, and gaseous fission products; changes in
various properties (e.g., thermal conductivity, volume swelling, mechanical
properties) induced by microstructural evolution; and radiation-induced phase
changes. Experimental studies using various advanced characterization
techniques for characterizing radiation effects in ceramics are of particular
interest. The irradiation techniques such as laboratory ion beam accelerators,
research and test reactors, as well as commercial nuclear power reactors are
all of interest. Computational studies across different scales from atomistic
to the continuum are all welcome. Contributions focused on novel fuels such as
doped UO2, high density uranium fuels like uranium nitrides and silicides, and
coatings for accident-tolerant fuel claddings are also encouraged. This
symposium is intended to bring together national laboratory, university, and
nuclear industry researchers from around the world to discuss the current
understanding of the radiation response of ceramics through experiment, theory
and multi-scale modeling.
This symposium will provide a venue for presentations regarding the use of
coherent diffraction imaging techniques (x-ray and electron diffraction
imaging, ptychography, holography) and phase contrast imaging techniques for
high-resolution characterization in all classes of materials. Additionally,
modeling and simulation methods that are relevant to nanoscale imaging
techniques will be included.
Background and Rationale:
A high degree of spatial coherence is an attractive property in x-ray and
electron beams. Those from modern synchrotrons and electron microscopes have
enabled the development of novel imaging methods. In some cases, these imaging
methods provide resolution beyond that achieved with optics and can also
provide remarkable sensitivity to a variety of contrast mechanisms.
The two methods that will be the focus of this symposium are coherent
diffractive imaging (CDI) and phase contrast imaging (PCI) with both x-rays and
electrons. Both explicitly take advantage of the coherence properties of the
incident beams. CDI has rapidly advanced in the last fifteen years to allow
characterization of a broad range of materials, including nanoparticles,
strained crystals, biomaterials and cells. PCI has been widely employed in
dynamics and engineering studies of materials, geophysics, medicine and
biology. Various techniques making use of both x-rays and electrons have been
developed that provide unique characterization abilities such as
three-dimensional strain mapping and non-destructive three-dimensional
quantitative tomographic imaging.
Increasingly, materials modeling at the atomistic and continuum scales is being
used in conjunction with these imaging techniques to enhance their capability.
Such combined imaging and modeling methods include building experimentally
informed models, which are in turn used to make predictions at spatio-temporal
scales inaccessible to the imaging technique, and the use of deep learning
algorithms trained on synthetic data. These pre-trained deep learning
algorithms are being used to improve the quality of acquired x-ray data, reduce
experimental measurement times and also reduce compute time required to recover
3D images from raw data.
Finally, as the new 4th generation x-ray light sources (Diffraction Limited
Storage Ring or DSLR) come online around the world, increasingly brilliant and
coherent x-ray sources will become increasingly important and applicable to
those wanting to understand materials behaviors at the mesoscale to nanometer
scale. Our 2021 symposium will have a special session dedicated to these new
exciting sources and their applications to materials.
Areas of interest include, but are not limited to:
(1) All x-ray based techniques including Bragg CDI, Fresnel CDI, ptychographic
CDI, propagation phase contrast imaging, interferometry imaging, and analyzer
based phase-contrast imaging
(2) All electron based techniques including ptychography and electron CDI
(3) Computational and simulation efforts with overlap in high resolution
imaging.
(4) Big data analytics and machine learning methods to accelerate data
abstraction and improve image quality
(4) All structural and functional materials systems needing high resolution
imaging
(5) Industrial applications
(6) Development of new techniques and new sources
Neutron and x-ray radiation sources offer new opportunities to advance the
fundamental understanding of nuclear reactor materials, fuels and engineering
components. A variety of advanced characterization tools including
diffraction, imaging and spectroscopy have recently become available to allow
measurements of microstructure and deformation over a range of relevant time
and length scales, on both pre- and post-irradiated materials, and under in
situ conditions including stress, corrosive media and temperature. The
symposium will highlight recent experimental efforts and future prospects to
characterize material and fuel systems for nuclear reactor applications using
neutron and x-ray radiation techniques. Areas covered will include
stress/strain evolution, void and crack initiation and propagation, structural
stability, phase stability and transformations, characterization of irradiation
defects, and corrosion. Specifically, the following areas are encouraged:
• In situ studies of dynamic processes including deformation, phase
transformations, recrystallization and corrosion.
• 3D imaging based on diffraction, phase, density, or elemental contrast.
• Characterization of irradiation-induced effects.
• Experimentation coupled with modeling.
Materials imaging and the analysis of the data play a central role in materials
characterization. The combination provides a way to `see' a material and
quantify its complexities leading to an understanding of its behavior under
various conditions. Combining experiments with complementary techniques such as
analytical spectroscopy allows one to gain a deeper insight into the relevant
physical phenomena. Materials imaging has reached a critical mass of data
generation partially due to faster and larger detectors, as well as advanced
microscopes and state-of-the-art light source facilities. Modern mathematics
and computer science tools are enabling the automation of data integration and
analysis; as well as opening new possibilities for extraction of quantitative
metrics from materials imaging.
This symposium solicits abstract submissions from researchers who are advancing
the field of materials imaging using novel techniques and developing new
methods that leverage high performance computational methods for analysis.
Image simulation, uncertainty quantification, and imaging data curation are
equally of interest. Session topics include, but are not limited to:
- Advances in materials imaging techniques, including in-operando conditions
- Fast imaging in support of high-throughput experimentation
- Automating experimentation: machine learning algorithms for image acquisition
and instrument control
- Workflows for automated data curation of microscopy data
- Advances in infrastructure for materials imaging and microscopic data
- Advances in simulations for materials imaging
- Approaches for data mining, machine learning, image processing, and
extracting useful insights from large imaging data sets of numerical and
experimental results and reuse of microscopic data

quantitative relationships among processing, microstructure, environment, and
fatigue properties; and life prediction. This symposium provides a platform for

Real Time Imaging. Respective papers will be selected to include in the joint

Solid state diffusion bonding is a welding process that is based on the atomic
diffusion across the mating surfaces to produce monolithic parts with
comparable mechanical properties to those of the bulk material. It often
performed at high pressures and temperatures to promote the interdiffusion
process. The technique is widely used in nuclear, aerospace, petrochemical, and
solar energy applications and used to join both similar and dissimilar
materials and alloys.
Nevertheless, the bonding process is highly sensitive to several factors such
as; surface finish, temperature, and pressure. In some cases, low-melting
interlayer is needed to promote the interdiffusion process. Bonding time is
always a major factor in the process; while increasing time allow atomic
diffusion to occur, it led to the precipitation of second phase particles in
the matrix and grain boundaries. This symposium will focus on recent progress
in the diffusion bonding processes performed in research environments as well
as on industrial scales, with special focus on:
1. Microstructural changes after the bonding process.
2. Changes in the mechanical properties in the bonded joins.
3. Precipitation in complex alloys.
4. Optimal bonding conditions for metals and alloys.
