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

Cold spray is a solid-state layer-by-layer deposition of accelerated
microparticles through a de Laval nozzle toward a substrate or previously
deposited particles. Since its discovery, interest in cold spray technology has
witnessed significant growth as it serves as a potentially greener
manufacturing alternative due to recent stringent environmental regulations.
Cold spray continues to enjoy widespread use in several industries, including
aerospace, energy, military, biomedical, etc., and continued efforts on process
and powder optimization are necessary to meet the anticipated expansion beyond
traditional applications. Exploring the structure-property relationship in
deposited materials, topics will include:
1. Experimental, theoretical, and computational studies on cold spray (and
related technologies) process, including aerosol deposition (vacuum cold spray)
2. Effect of processing and feedstock parameters on bonding
3. Powder development and optimization
4. Microstructural evolution and evaluation of high-speed microparticle impact
5. Mechanical and deteriorative behavior of cold-sprayed components
6. Cold spray-induced stress-state
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

crystallographic texture, grain morphology, dislocation structures accompanying
deformation. In combination with modeling, these techniques improve our

The purpose of the furnace containment system is to hold both process materials
and energy associated with pyrometallurgical processes. The methods in which
the challenges of containing corrosive and abrasive materials at extreme
temperatures will be addressed, whether they are used across commodities or

cross-technology perspectives. The intention of this symposium is to create a
platform for the exchange of ideas on the challenges, solutions, failures, and
successes in furnace containment designs and applications. Bringing together
perspectives from industry, design houses, and research institutions will be
ideal. For the symposium, the furnaces associated with solid-state processes

Ceramics and ceramic-based composites play an important role in nuclear
industry as they can be used to generate nuclear power and dispose of
radioactive nuclear waste. For instance, nuclear graphite has been used widely
in gas-cooled reactors, either in prismatic designs or pebble-bed
configuration, as a fast-neutron moderator as well as structural components.
Graphite composites and SiC-based ceramics are also used as matrix for TRISO
fuels (pellets or pebbles). SiC ceramic-matrix composites in tubular shape, on
the other hand, have been investigated as an alternative to conventional
Zircaloy as accident tolerant fuels. Lastly, ceramics, such as borosilicate
glass, are also adopted in the immobilization/storage of nuclear waste. The
nano-/micro-structure and the thermal/mechanical properties of these materials
evolve with irradiation in service, and it is critical to understand the
underlying mechanisms via experimental and modelling methods. It is therefore
essential that a symposium brings together experts/scientists across the world
to share knowledge and experience on these materials to inspire novel and
transformative ideas. The primary topics of interest to this symposium are:
• Fuels: UO2, UCO, MOX, and TRISO (stand-alone particles or embedded in
graphite or SiC matrix)
• Nuclear graphite: reactor core components or as matrix material for TRISO
• Waste management: borosilicate glasses and other relevant materials
• Experimental characterization: microstructural evolution, degradation
behaviours
• Properties: thermal and mechanical properties
• Modelling of ceramic degradation mechanisms and properties
The symposium focuses on the advancements of characterization of the minerals,
metals, and materials and the applications of characterization results on the
processing of these materials. Subjects include, but not limited to, extraction
& processing of various types of minerals, process-structure-property
relationship of metal alloys, glasses, ceramics, polymers, composites,
semiconductors and carbon using as functional and structural materials.
Advanced characterization methods, techniques, and new instruments are

There have been recent advancements in the use of cold spray processing for
non-traditional applications. However, its widespread use in several
industries, including aerospace, energy, military, biomedical, etc., rests on
understanding the solid-state adhesion process that spans micrometer-scale
spatial and nanosecond-level temporal resolutions. This symposium covers
research efforts and advances in areas not limited to cold spray process
optimization, microstructural evolution, bonding mechanism, and mechanical and
deteriorative performance of buildups and deposits made with cold spray and
allied technologies.
Efforts to achieve more environmentally friendly materials and manufacturing
process is an increasingly important topic. Natural sourcing and recycling of
raw materials along with improvement of component life cycle enhancement to
reduce waste are often targeted in all engineering sectors. This symposium
focuses on innovations in the field of composite materials with a specific
focus on Eco-Friendly and environmentally sustainable systems. Work focused on
these activities in all composite fields are invited including polymer, metal,
and ceramic matrix composites. Emphasis on sourcing raw materials in a
sustainable way as well as development of composite materials for environmental
sustainability are encouraged. Papers looking at both the development of new
materials for structural applications, reduction in energy consumption, and
increased component life along with discussions of novel methods to reuse
existing materials are encouraged. Additionally, papers focusing on the
characterization of such materials are also invited. All submissions should
focus on the merging on composite materials and environmental impacts.
Specific Topics of interest include Naturally Sourced Materials feedstock,
Recycled Material feedstock, application of composite for reduced carbon
footprint and development of novel materials to repurpose waste from other
areas.
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.

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
This symposium provides an opportunity of sharing recent advances in
microstructure, phase transformations, properties, mechanical and stress
corrosion, of light-weight composites (metal matrix, ceramic matrix and polymer
matrix) and materials. Focus will also be on the improvements in composites
containing boron compounds for high temperature applications. The next
generations of alloys and composites for Aerospace, Automotive and other
structural applications will be expected to possess multiple advanced
properties in addition to high strength and toughness. In Aerospace
applications, the composites will be subjected to much greater extreme
conditions of temperature, pressure and radiations. This annual conference
attracts materials scientists and engineers from all over the world, and
provides a venue for faster technology dissemination.
Objective: This symposium will provide a venue for presentations featuring the
use of advanced characterization techniques in all classes of materials to

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.

imaging

Natural fibers are a renewable resource ready to be used in many new
applications due to their abundance worldwide, excellent properties, low cost,
and green solution. There has been an increasing interest in research and a
growing industrial sector, with a high potential to significantly reduce the
CO2 footprint of other traditional materials and processes. On the other hand,

Many a metallurgist fell in love with pyrometallurgy after witnessing a smelter
being tapped. There is something magical in the combination of light, energy
and danger that simultaneously stirs the primal instincts to ‘run for your
life’ and ‘go closer and have a look’.
But tapping a smelter is not an easy task.
Much engineering go into the design of the tap-hole. Due to the aggressive
nature of the process, material selection is as important as layout. The design
process kicks off with a set of design criteria, which needs to be revised as
the results of laboratory, compational fluid dynamics (CFD) and time-and-motion
studies become available. The tap-hole life-cyle is taken into account with
designers addressing the requirements for installation and operability as well
as for maintenance. Matters such as online monitoring of the taphole wear,
handling of liquid products, and extraction of fumes are all taken into
account.
Though tap-hole life can be improved with proper design, a good design can be
destroyed with incorrect tapping practices and equipment. Despite the harshness
of the tapfloor environment, it requires precision equipment and operating
practices. The design and maintenance of the drilling, tapping and plugging
equipment and materials plays an equally important role in tap-hole life and
tapfloor safety. As does protective equipment. Operators want the tap-hole life
to be as long as possible since tap-hole failures is often the cause for a
reline—a very expensive exercise in an upcycle when the cost of a new lining is
small compared to the loss in production. Managing the maintenance and reline
schedule is a challenge with lessons often learned the hard way.
The first thing students are taught in pyrometallurgy courses is how to compile
a mass and energy balance for a smelter. An accounting mass and energy balance
is used not only to schedule furnace taps but also to make process decisions.
Process variables measured during or after tapping are important inputs to a
workable mass and energy balance.
Even though much has been done to make the tapping process as automatic as
possible, tapping of smelters cannot be done without labour. Tap floor
operators work in harsh environments where safety is of utmost importance.
Selection of suitable personnel and intensive training is required.
No pyrometallurgical smelter can operate without some form of tapping system.
It is the one thing all smelters have in common. A meeting point of science,
technology and skill.
So let us talk about it.
Objective: This symposium will provide a venue for presentations regarding 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

in combination with modeling, are improving our understanding of deformation
and failure during material processing/forming and under normal or extreme

understanding of individual mechanism interactions and direct validation of
plasticity models. This gathering provides a place to talk about new advances

This symposium focuses on the development and use of computational and data
intensive characterization capabilities used by experimentalists and modelers
to investigate materials structure and mechanisms at varying length and time
scales. Advancements in computational processing power; instrument and detector
capabilities; and multi-scale experimental and modeling techniques are
generating increasingly large datasets that have facilitated the discovery of
quantitative descriptors that link structure to processing parameters and
material properties. For example, experimental techniques such as 3D x-ray and
synchrotron tomography; atom probe tomography; multi-modal imaging; and high
frame rate imaging are generating enormous characterization datasets used to
understand and quantify material structure and behavior. Similarly, atomistic
and mesoscale simulations are generating large datasets that provide insights
for the genesis and evolution of various microstructural features, and provide
links to higher order models and experiments. Throughout the materials
community, scientific discoveries using these large characterization datasets
are being accelerated through the advancement and automation of analysis
techniques such as machine learning and artificial intelligence. As these
computational and data intensive characterization approaches advance, there is
a call for deeper study to quantify their inherent uncertainty of structural
descriptors.
This symposium intends to bring together experimental and theoretical experts
in computational and data intensive microstructure characterization from both
academia and industry, with a focus on the methods and techniques to
effectively manipulate, reconstruct, analyze, and apply these data to develop
improved predictive capabilities for multi-scale materials design. Suggested
areas of focus for this symposium include:
• Theoretical and computational development of novel structural descriptors to
characterize microstructural features (e.g. grain boundary atomic and
crystallographic structure, crystallographic texture, distributions of triple
junction types), and their application to quantitatively characterize
experimental and simulation data, and develop new predictive
microstructure-property models.
• Methods and algorithms for collecting, reconstructing, analyzing, and
quantifying large experimental microstructural datasets collected from tools
such as: atom probe tomography, x-ray computed tomography, or high-speed
measurements.
• Methods and algorithms for the detection, analysis, and quantification of
microstructural features predicted through atomic and mesoscale simulation
data. Validation approaches for computational and theoretical models using
structural descriptors and advanced experimental mechanics techniques. Methods
to bridge modeling and experiment through computed characterization (e.g.
virtual X-ray and electron diffraction and simulated microscopy).
• Application of advanced analysis techniques, such as machine learning and
artificial intelligence, to develop multi-scale microstructure descriptors and
provide greater insights into materials characterization data.
• Methods for quantifying the uncertainty inherent in manipulation,
reconstruction and analysis of large sets of characterization data.

cells is high purity silicon. For the industry to mature and grow into green
production, improvements in Si production, refining and crystallization
processes, emission control and recycling needs to be carried out.

in furnace design and process intensification, novel techniques of silicon
production, thermodynamic and kinetic modelling).
- Silicon refining and behavior of impurities (all types of metallurgical
upgrading approaches: solvent refining, slag refining, electrolysis/FCC
Cambridge process, gas blowing/oxidation refining, plasma refining, vacuum
refining, solidification techniques, optimization of the Siemens-like routes)
