Stability of structural materials is of great importance to avoid catastrophic
failures during operation across the aerospace, transportation, and energy
fields. Stability is significantly affected by processing route. Understanding
responses to stress, hydrostatic pressure, temperature, irradiation, or
corrosive conditions is essential for designing alloys for all service
environments. This symposium delves into investigations, focused on using high
throughput tools for accelerated materials discovery and root cause analyses of
fielded and new make parts. This symposium will also help identify some
critical areas/needs in new methodologies/tools for the community to focus upon
and how they are being validated and corroborated with experimental evidence.
The topics of interest to this symposium include, but are not limited to, the
following:
• Integrated computational materials engineering (ICME) tools coupled with
multi-scale experimentation to correlate processing history to microstructural
hierarchy and ensuing property response
• Novel modeling approaches for reliable prediction of material properties,
including multi-objective optimization and machine learning based approaches
• Unraveling the complex interplay between driving forces and mobility for
competing microstructure evolution processes
• Mechanisms of material responses to combined chemo-thermo-mechanical loading
and modeling that incorporates new mechanistic understandings of behavior
• High throughput experimental approaches to facilitate training of machine
learning models
• Qualification pathways and status of qualification for next generation
materials and manufacturing processes
One session of this symposium will focus on materials scientists and engineers
who work on alloy development for a wide range of industrial applications
providing a forum to discuss the methodology for design, property optimization,
and successful and unsuccessful techniques or examples. Uniting academia and
industrial research will facilitate a fruitful interaction on the newest
techniques being developed and the experiences of alloy developers in their use.
This symposium has historically been primarily focused is on structural high
temperature materials such as refractory alloys; high-entropy alloys,
medium-entropy alloys, complex concentrated alloys and alloys proposed under
similar design concepts; Co-, Ni-, Nb-, and Ti-based alloys; maraging steels;
alumina-forming steels; and ODS alloys. Abstracts involving multiple processing
routes are welcome, including additive manufacturing, powder metallurgy,
casting, wrought processing, and combinations thereof.
New reusable rocket engines currently under development use high efficiency
staged-combustion power cycles which subject materials to extreme operating
conditions, involving cryogenic temperatures, extreme temperature swings, high
heat fluxes, and ultra-high-pressure oxygen. These conditions give rise to a
host of catastrophic failure modes, from metal fires to oxidation-assisted
fatigue to strain-ratcheting induced creep rupture. Legacy materials were used
to design and fabricate current reusable rocket engines. Companies are now
racing to update technology and develop new platforms, but the challenges are
formidable and require collaborative teams. There are exciting opportunities to
apply modern design and development tools and to exploit huge advances in
materials over the past 20 years to specifically tailor materials to meet the
extreme environments of reusable propulsion systems. The three components that
dictate the life of a reusable boost-stage staged-combustion rocket engine are
the thrust chamber, turbopump and nozzle. Each operates in disparate conditions
that drive distinct failure modes, motivate different material choices, and
present unique research opportunities. This symposium will feature talks on the
material behaviors and failure modes in these applications as well as novel
materials, manufacturing processes, and structures that can overcome these
failure modes to unlock advances in reusable rocket engine technology.
High-temperature alloys continue to play a vital role in many applications and
industries, such as aerospace and energy. Key aspects of development efforts
include improving system efficiency by raising the maximum operating
temperature, improving the strength/density ratio, and ensuring long-term
mechanical performance. In recent years, there have been advances on several
fronts, such as the design of novel Co-based superalloys, multi-principal
element alloys, refractory systems, and predictive capabilities for lifetime
performance. This symposium aims to provide a setting for submissions from
academia, government, and industry to discuss recent advances in understanding
the fundamental behavior, structure, properties, and performance of
high-temperature alloys.
High-temperature alloy systems remain integral to structural applications in
the aerospace, automotive, and power generation industries. The phase
transformations occurring during fabrication and post-processing are critical
in establishing the desired properties of these alloys. Conversely,
transformations during manufacturing or in-service can lead to failure.
Understanding the mechanisms behind these phase transformations and their
influence on material properties is essential for the successful design and
application of these alloys under elevated temperatures. Topics of interest
include recent experimental and computational advances in the field of phase
transformations of high temperature alloys, across the spectrum from model- to
commercially-offered-alloys. Such alloys include aluminum-base, titanium-base,
iron-base, nickel-base, refractory-base, and multi-principal-element alloys, as
well as intermetallic systems.
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.

Bcc-superalloys are a nascent class of material, with a microstructure
comprising a body-centered-cubic matrix (eg refractory metal, Fe, Ti)
reinforced by ordered-bcc superlattice precipitates (eg B2 NiAl), with analogy
to the highly successful gamma gamma-prime in fcc nickel based superalloys.

For over thirty-five years, Professor Brian Gleeson has been a leader in
corrosion science advancing understanding of the high temperature oxidation and
degradation of alloys and coatings. Brian has illuminated key thermodynamic and
kinetic aspects controlling the degradation of materials in harsh environments,
from gas/solid reactions to diffusion in the alloy and everything in between.
Brian's research career has included positions in Canada, Australia, and the
USA. Brian began his academic career at the University of New South Wales in
1990, moving to Iowa State University in 1998, before settling at the
University of Pittsburgh in 2007 where he builds upon a rich history of high
temperature corrosion research at the school. Throughout this time Brian’s
expertise, unassuming nature, and genuine interest in both research and
teaching has helped to shape countless students and young researchers
comprising the next generation of high temperature corrosion scientists and
engineers.
This symposium serves to recognize the exceptional quality of research and
mentorship that Brian has demonstrated throughout his career. As with Brian’s
own research, this symposium will cover
all aspects of the high temperature corrosion process. The aim of this special
symposium is to provide a forum for scientists and engineers to present and
discuss recent work on current understanding and characterization of corrosion
in high temperature aggressive environments. To align with Prof. Gleeson’s
areas of research, specific forms of degradation include but not limited to
mixed-gas attack (e.g., oxidation-sulfidation, oxidation-carburization,
oxidation-chloridation), hot corrosion, deposit-induced attack, and metal
dusting. These forms of attack may be in combination with some form of
mechanical loading (e.g., fatigue and creep) and/or thermal cycling.
High temperature materials are used in aerospace, power generation, and
chemical processing industries where components are expected to withstand
superior temperatures, high stresses, and reactive environments during service
intervals that last for decades. In order to design these components, methods
to accelerate service degradation are needed such that a mechanistic
understanding can be developed in a much shorter time frame, typically on the
order of months. In this symposium, abstracts are requested on topics including
but not limited to:
• Accelerated creep and fatigue testing methodologies, modeling frameworks, and
prediction capabilities
• Modeling and/or experimental methods to accelerate microstructure evolution
and/or mechanical property degradation at elevated temperatures and/or
aggressive environments
• Experimental methods to accelerate environmental interaction of high
temperature materials
• Interactions of creep, fatigue, environmental effects, and microstructure
evolution
High temperature alloys continue to play a vital role in the transportation and
energy industries. While both sectors look to improve the system efficiency by
raising the maximum temperature the alloys can withstand, the transportation
industry is also focused on lightweighting. In recent years we have seen
advances in a number of different alloy systems. This symposium aims at
providing a setting for researchers from academia, government, and industry to
discuss recent advances in the understanding of various mechanisms that
influence the strength, service life, and environmental resistance of high
temperature alloys.
Most industrial applications such as the aerospace, automobile, biomedical and
defense areas need materials that must operate in increasingly extreme and
complex environments. Usually no single existing alloy can meet all the
requirements of a desired system component. Thus, the successful design and
processing of a gradual change in composition and microstructure, and therefore
properties, over the whole material is gaining considerable attention in
materials science and engineering. Graded materials, coatings and claddings
allow for unique combinations of properties to enable various harsh
environment, functional and structural applications. In practice, functionally
graded materials (FGMs) are often susceptible to processing defects linked to
prohibitively time-consuming, empirical process development without the ability
to predictively determine and/or rapidly screen experimentally viable pathways
(composition and process parameters) to optimize their production. Due to these
limitations, the actual performance of FGMs, relative to conventional parts,
remains to be validated and optimized. This symposium focuses on all aspects of
the science and technology, from fundamental science to industrial
applications, that will enable control of the microstructure and properties of
graded materials coatings and claddings, including: thermodynamic, kinetic,
property, and microstructure evolution simulations; rapid processing; in situ
characterization; and understanding defect formation.
Many types of gradient systems are of interest, including from one alloy
composition to another, from metals to ceramics, and from intermetallics to
metals. Advances in coating technologies, new compositions of coatings, and
advanced manufacturing techniques are of interest. Specific topics include, but
are not limited to:
• Fundamental issues and underlying mechanisms in processing FGMs, coatings,
and claddings
• Development and demonstration of computational-experimental platforms to
produce viable graded components ready for various types of advanced testing
• Novel graded material combinations, coatings, and claddings for targeted
applications (i.e., optimized mechanical, functional and corrosion properties)
• Understanding of solidification, phase stability, and phase transformation
in FGMs
• Computational prediction of optimal material gradients and properties with
minimal processing defects, such as porosity
• Advanced processing methods for FGMs, coatings, and claddings: additive
manufacturing, physical vapor deposition, pack cementation, slurry c coating,
powder-based laser deposition, cold spray, thermal spray, and friction stir
processing
• Novel techniques and characterization methods for rapid FGM, coating, and
cladding optimization
High temperature alloys, including Ni-based, Ni-Fe-based and Co-based
superalloys, are critically important in enabling technological advancements
from the aerospace to the power generation, chemical processing and
manufacturing industries to atomic energy. Fundamental to the performance of
these materials are their deformation characteristics, both in terms of the
deformation necessary during manufacture as well as the deformation sustained
during service. Critical developments in the field of high temperature alloys
in recent years have been reliant on controlling and utilising deformation and
deformation induced phase transformations to achieve superior performance at
increasingly higher temperatures. Such advances have been further enabled by
the unparalleled innovation in the advanced characterisation methods and data
analysis tools used to investigate deformation characteristics in these
materials, such as dynamic TEM, atom probe tomography, high resolution EBSD,
advanced neutron and synchrotron X-ray diffraction and resonant ultrasound
spectroscopy, to name a few.
The aim of this symposium is to bring together the community to discuss the
effect of deformation on microstructural control and performance in high
temperature materials (Ni, Ni-Fe, Co superalloys, refractory metal alloys,
multi-principal element alloys) through the lens of advanced characterisation.
The proposed technical scope of the symposium includes (but is not limited to):
• Novel insights into deformation mechanisms obtained from advanced
characterisation and modelling validation methods; including elemental
segregation, phase-specific deformation characteristics and defect evolution.
• Deformation assisted microstructural control of high temperature alloys
during manufacturing processes (including powder metallurgy and additive
manufacturing methods).
• Deformation determined in-service performance of materials for high
temperature structural applications (including mechanical performance as well
as environmental resistance).
• Co-operative chemistry and processing design for improved alloy performance.
• Deformation effects on “finishing operations” including machining, heat
treatment and shot peening.
• Effect of deformation on phase and property evolution.
• High throughput methodologies for deformation assessment in manufacturing and
in service performance.
• Role of deformation in phase transformations and microstructural evolution.
• Non-destructive and correlative evaluation of deformation accumulation during
manufacturing and under in service conditions.
This symposium is by invitation only.
Through his creativity and scientific excellence, Easo George has made seminal
contributions to metallic materials research. During his long tenure at the
Oak Ridge National Laboratory and the Alloy Behavior and Design Group, most
recently as Governor’s Chair, he has led the nation’s most active alloy
development research activities. His expertise in phase transformations and
alloy processing has enabled innovations in intermetallics, refractory alloys,
and high entropy alloys. His group’s research has provided insights in the
wide-ranging topics of ductility and fracture behavior in intermetallics,
deformation behavior of refractory metals, and compositional effects in high
entropy alloys. In addition, his innovative work on the solidification of
eutectic single crystal microstructures provided a unique pathway for creating
small material volumes for exploring size effects in mechanical behavior. In
addition to the impact of his group’s own research, he also generously enabled
the research efforts of many collaborators by providing alloys with highly
controlled chemistries and microstructures.
This symposium will provide a forum for presentation of topical advances in:
• Principles of alloy behavior and design
• Strategies for defeating the strength-ductility “trade-off”
• Compositionally complex (high entropy) alloys
• Small-scale mechanical behavior
• Links between deformation mechanisms and mechanical behavior
• Advanced metallic alloys and intermetallics for high temperature structural
applications
Given the simultaneous development of high temperature alloys and manufacturing
processes, it is necessary to investigate the effects on creep properties of
these coexisting advancements. With the resurgence of high temperature
refractory alloys and oxide dispersion alloys through the relatively new
material class of multi-principal element alloys and the advent of other such
superalloys, it is critical to re-examine conventional behaviors of creep as
these new alloys introduce additional mechanisms that have not been
traditionally observed. Beyond compositional advances, there have been
exceptional fabrication and processing advances in the last decade such as
those in additive manufacturing that directly impact the creep properties of
these materials. This symposium focuses on the new challenges and new
opportunities in advanced structural materials for service under extreme
conditions and poses a reconsideration of what is thought to be typical high
temperature creep behavior given this ever changing materials landscape.
Supersonic and hypersonic regimes require materials resistant to high
temperature and high-rate deformation to survive extreme aerodynamics and
aerothermal conditions. Furthermore, candidate materials must retain high
strength and sustain oxidation, creep, fatigue, and widely varying cyclic
thermal gradients. Although limited in the application space, several candidate
materials such as composites, ceramics, and refractory multi-principal-elements
alloys (MPEAs) hold the potential to satisfy these needs. Improving existing or
developing new materials requires integrating both simulations and experiments
to cover all length scales, temperatures, and strain-rates. Simulation can fill
gaps where experiments are not possible or supports experimental results
analysis when in-situ observations are unpractical. This symposium intends to
foster presentations and discussions around new approaches to design next
generation materials beyond supersonic applications. We invite abstracts
submission on the following topics for high temperatures and high strain rates
applications:
- Simulations for accelerated alloy design (CALPHAD, crystal plasticity,
phase-field, atomistic…)
- Microstructures and mechanical properties (uni- or multi-axial loading,
damage, fatigue…)
- Degradation (corrosion, oxidation, wear…)
- Advanced in-situ characterization techniques (electron microscopy, high
energy X-ray diffraction and tomography…)
- 3D characterization (electron back scattered diffraction, high energy X-ray
diffraction and microscopy…)
- Advanced processing for metastable materials and near-net shape components
- Coatings and internal cooling systems
High temperature alloys, notably Ni-, Co- and Fe-based superalloys are enabling
materials for the design of high-temperature components for aerospace
propulsion, chemical processing, oil and gas applications, and power
generation. They retain superior strength at elevated temperatures, and show
excellent damage tolerance, toughness, long-term stability and resistance to
creep accumulation and environmental damage. The performance of these alloys
is often improved when formed to optimize microstructure or used in conjunction
with surface treatments and coatings or with novel design solutions. The aim
of the symposium is to discuss the mechanisms of deformation and damage in the
manufacture, application and refurbishment of high temperature alloys,
principally Ni, Co and Fe based superalloys but also high entropy or
multi-principal element alloys and refractory alloys. It is proposed that the
technical focus is in understanding:(i)Roles of deformation and heat treatment
on the evolution of microstructure during material processing, (ii)Effects of
deformation from manufacture on material and component behaviour,
(iii)Mechanisms of deformation that determine material behaviour,
(iv)Development of deformation that gives rise to damage during material
application, (v)Effects of composition and microstructure on resistance to
deformation and damage accumulation, (vi)Refurbishment, rejuvenation and life
extension processes. Topics of interest may include (but are not limited
to):(a)Elevated temperature forging, recrystallization, grain growth, flow
forming, machining and shot peening, (b)Advanced solidification techniques and
impact on properties, (c)Experimental observation of deformation and damage
accumulation, (d)Constitutive and computational modeling of deformation,
(e)Mechanisms of ambient and elevated temperature plasticity, creep, fatigue
(LCF, HCF, VHCF), creep-fatigue, crack growth and environmental damage.
The growing field of Additive Manufacturing (AM) provides new exciting
challenges and opportunities in physical metallurgy. Inherently different to
traditional manufacturing processes, in AM, metallic systems undergo various
localised phase transformations in fractions of a second during a build. For
instance, the layer-by-layer approach gives rise to the so-called intrinsic
heat treatment, where earlier layers continuously experience a temperature
gradient induced by the melting of subsequent layers. This often results in an
inhomogeneous microstructure throughout the build, and in some cases,
precipitation can be triggered from early stages. Therefore, there is a need
for AM-tailored post-processing conditions.
For a wider adoption of the technology in industry, the knowledge on the
microstructure needs to be extended to its stability in service, including high
load and temperature conditions. Such understanding will provide a solid
background in the design of microstructures tailored for the AM process, and
bring us a step closer in establishing the materials paradigm for AM.
Topic of interest include, but are not limited to:
* Microstructural characterisation of AM-processed materials throughout
post-processing.
* Physical modelling / simulation of phase transformations and microstructural
evolution.
* Phase transformations and microstructural stability of AM components under
extreme conditions.
* Effects of powder manufacturing process and recycling on phase stability.
* Processing effects on as-built microstructure gradients and texture.
Superalloys are critical to operation and future design of a wide variety of
propulsion and power generation components in the aerospace, marine, and energy
industries. Their industrial application is often driven by excellent long-term
stability and durability at elevated temperatures or in aggressive environments
because they display a good balance of mechanical strength, fatigue and creep
resistance, as well as corrosion and oxidation resistance. The symposium aims
to attract papers on current and state-of-art application of Ni- and Co-based
superalloys. Topics of interest may include (but are not limited to):
• Viability of fabrication with additive manufacturing methods (powder bed
techniques and direct energy deposition)
• Relationships of metallurgical processing with microstructure and
performance (i.e. casting, forging and heat treatment)
• Mechanisms of ambient and elevated temperature plasticity, creep, fatigue,
creep-fatigue, crack growth and environmental damage
• Mitigation of environmental, thermal, and thermal mechanical damage,
including improved coatings for service operation
• Advancement in joining, repair, and rejuvenation of superalloys
This symposium is a continuation of four previous successful symposia held at
TMS annual meetings in 2001 (Indianapolis), 2006 (San Antonio), 2012 (Orlando)
and 2016 (Nashville). It serves as a periodic review of the state-of-the-art
development on the subject. In this symposium, we will bring together materials
scientists and engineers to share their experiences, including successful and
unsuccessful examples, challenges, lessons learned, in developing wide variety
of class of alloys for industrial applications, as well as new tools and
methodologies that enable efficient alloy design and accelerated implementation
processes. The interaction between the two groups will bridge the gaps between
them, thus accelerating the transition of new design tools to alloy
development. Covering both past experiences and new approaches – both
experimental and computational, this symposium will also help identify some
critical areas/needs in new methodologies/tools for the community to focus
upon. Applications of artificial intelligence and machine learning to alloy
design are one of the new areas of interest in this symposium.
