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.
One main objective of this high-entropy materials (HEMs) symposium is to
connect the high entropy alloys (HEAs) or the more broadly defined
multi-principal-element alloys (MPEAs) community with the conventional
materials community that has already created a vast number of multi-component
compounds, such as intermetallics, ceramics, and functional materials. Another
objective is to promote the design and development of high-performance
materials for industrial applications exploring complex composition. It is
recognized that configurational entropy does not always dominate materials
properties, and efficient and reliable methods are urgently needed to
accelerate discovery of new cost-effective materials for wide arrays of
industrial applications. As such this symposium solicits recent quality
research on fundamental understanding and applications of high-entropy
materials.
Topics of interest include but not limited to:
(1) Combinatorial synthesis methods in bulk and thin film forms
(2) Advanced manufacturing and joining (e.g., additive manufacturing, friction
stir welding)
(3) Novel microstructures (e.g., heterogeneous, hierarchical, short-range
ordering)
(4) High-throughput characterization of the phases, microstructures, and
properties
(5) Advanced characterization, such as neutron and synchrotron scattering and
atom probe tomography
(6) Thermodynamic and kinetic properties
(7) Mechanical properties (e.g., elasticity, plasticity, strength, hardness,
wear, ductility, toughness, creep, and fatigue)
(8) Other physical and functional properties, such as electric/ionic/thermal
conductivities, and magnetic, magnetocaloric, thermoelectric, superconducting,
dielectric, optical, catalytic) properties.
(9) Environmental properties (e.g., aqueous corrosion, oxidation, erosion,
irradiation, hydrogen storage, cryogenic temperatures, elevated temperatures,
high pressure, high strain rates)
(10) Interfaces in HEMs and other defects (e.g. vacancy, stacking fault, twin,
dislocation, grain boundary, and surface, etc.)
(11) Theoretical modeling and simulation using density functional theory,
molecular dynamics, dislocation theory and dynamics, Monte Carlo, phase-field,
CALPHAD, and continuum.
(12) Machine learning, artificial intelligence, machine learning potential
development, inverse materials design.
This symposium will focus on the ongoing computational efforts to develop
scientific understanding of high entropy materials (HEMs). Due to the presence
of multiple elements in large proportions that are randomly distributed on a
crystal lattice, on the one hand, HEMs present exciting opportunities for rich
physics, whereas on the other, their large phase space leads to a multitude of
challenges from computational expense to model development. The field has
multiple open lines of questioning in the areas of phase stability, electronic
frustration, lattice distortion, short-range order, grain boundary,
dislocation, and microstructure. These features are well-known to be
responsible for novel HEM properties including mechanical, thermophysical and
electrochemical. Various computational modeling and simulation approaches are
being used to unveil underlying correlations between the features and the
properties. The symposium seeks abstracts that develop and apply such
computational approaches at electronic, atomic, mesoscale, and multiscale
levels to discover, understand and engineer new HEMs including alloys and
ceramics.
Data-science modeling is playing a crucial role in developing understanding of
structure-property-processing relationships, and in addressing the phase-space
challenge in HEMs. These efforts are being assisted by emerging data
repositories. The symposium also seeks abstracts on new data-science approaches
being developed and deployed for HEMs. Finally, the symposium will also
consider ICME approaches and their applications to HEM manufacturing.
Some examples include:
• Novel electronic-structure based methods and tools to understand phase
stability, free energy, structure-property understanding, etc.
• Molecular dynamics and Monte Carlo simulations to understand deformation and
microstructure evolution including interatomic potential development.
• Thermodynamic modeling for predicting microstructure and phase stability.
• Mesoscale and multiscale modeling to understand grain boundary and
microstructure evolution.
• Data-science and high-throughput approaches to materials design.
• Data-science frameworks, data-repository development, and approaches to
analyze experimental results.
• Computational methods for HEM development for extreme environments.
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 gives an avenue for scientists, researchers, and engineering to
present their recent applied and theoretical research results on a number of
topics regarding the mechanical behavior of high-entropy alloys (HEAs) or
multi-principal element alloys (MPEAs).
BACKGROUND AND RATIONALE: HEAs and MPEAs contain five or more primary elements
and can consist of a combination of body-center-cubic (BCC),
face-centered-cubic (FCC), and hexagonal-close-packed (HCP) solid-solution
phases. These alloys have also been found to possess many desirable properties,
such as exceptional corrosion and irradiation resistance, high strength and
ductility, and high fatigue/wear resistance. These desirable characteristics,
therefore, make HEAs/MPEAs potentially viable candidates for several industries
including those in the energy, biomedical, automotive, and aerospace sectors.
Topics of interest include, but are not limited to:

electron backscatter diffraction, and three-dimensional (3D) atom probe
tomography
(4) Innovative computational modeling and simulation techniques, such as
phase-field modeling, molecular dynamics, Monte Carlo, CALculation of PHAse
Diagrams modeling, finite-element methods, density functional theory machine
learning methods, and integrated computational materials engineering (ICME)
(5) Microstructural control, such as hierarchical structure, which modifies the
physical and mechanical behavior
(6) Applications of mechanical properties in the nuclear, aerospace,
biomedical, and other industries
This symposium addresses synthesis, transport property, phase stability, and
phase transformation of the alloys and compounds used in thermoelectric and
solar cell devices. Materials of interest include but are not limited to

This symposium will bring together experts in advanced theory, computation and
experimental characterization of microstructural evolution during solid-state
phase transformations and plastic deformation in complex multicomponent alloys.
The development of modern computational and experimental tools has led to
better fundamental insights into pathways and mechanisms of solid-state
transformations and deformation. The symposium will survey the current
state-of-the-art fundamental understanding of transformation and deformation
mechanisms and the intrinsic coupling between the two processes, leading to the
development of new alloy design principles and strategies. Since integration
between experiment and computation has become a hallmark in alloy
microstructure science and engineering, sessions will cover mechanism-based
modeling and simulations motivated and informed by experimental
characterization and novel alloy microstructure design and engineering guided
by computation. The specific topics will include but not be limited to: (1)
Phase transformation pathways and deformation mechanisms in complex
multicomponent alloy systems such as Ni-/Co-base superalloys, Ti-, Al- and
Mg-alloys, HEAs, and shape memory alloys; (2) Phase transformation and
deformation in compositionally and/or structurally modulated or graded
materials.
Presentations in this symposium are by invitation only.
Materials development for extreme environments including high temperature
turbines and nuclear reactors involves the development of alloys which are
resilient against a variety of degradation mechanisms. These degradation
mechanisms include oxidation/corrosion, hydrogen embrittlement, precipitation
hardening or instabilities, phase decomposition, fatigue, and wear. Traditional
structural alloys such as austenitic steels and Ni superalloys, as well as new
material systems such as multicomponent alloys or multiple principal element
alloys can all suffer from a variety of phase instabilities that are likely to
impact long term performance. Understanding material stability in these extreme
environments is paramount to enhancing the lifetime of key components.
The purpose of this symposium is to create a forum where researchers from
across academia, national laboratories, and industry can share insights on
recent advancements and the practical impact of phase stability on the
performance of alloy systems. This includes current materials for applications
such as light water reactors and power/aviation turbine systems as well as
future applications such as fusion reactors and hydrogen power systems. A
variety of perspectives from modeling and simulation to predict behavior and
lab scale testing to failure analysis of field components will help to create a
fuller understanding of mechanisms and impact.
Experimental and/or theoretical studies are sought on topics including but not
limited to:
-Phase separation or decomposition in extreme environments
-Radiation induced phase transformations
-Deformation induced phase transformations (e.g. deformation induced martensite)
-Long term thermal aging
-High temperature thermal cycling
-Impact of phase stability on hydrogen embrittlement
-Impact of phase stability on stress corrosion cracking
This is the 23nd in a series of TMS symposia addressing the stability,
transformation, and formation of phases during the fabrication, processing, and
utilization of electronic materials and devices. Topics of interests range from
microelectronic technologies to advanced energy technologies, including phase
stability, transformation, formation, and morphological evolution of electronic
packaging materials, interconnection materials, integrated circuit materials,
optoelectronic materials as well as energy storage and generating materials.
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…)

energy X-ray diffraction and tomography…)

diffraction and microscopy…)
- Advanced processing for metastable materials and near-net shape components
- Coatings and internal cooling systems
The thermodynamics and kinetics of alloys play a pivotal role in understanding
and optimizing their properties and performance. This symposium aims to bring
together experts from academia, industry, and research institutions to exchange
knowledge, discuss recent advances, and explore future directions in the field
of thermodynamics and kinetics of alloys.
The symposium will cover a wide range of topics related to thermodynamics and
kinetics of alloys, including, but not limited to:
Experimental investigations of thermodynamics and kinetics of alloys, such as

researchers working in the field of both experiment and modeling to discuss the
latest advancements and challenges related to thermodynamics and kinetics of
alloys.

Materials design is critical for manufacturing innovation. Different processing
introduces a variation of process-structure relationships for the same alloy.
Therefore, it becomes essential to integrate the efforts of materials design,
processing optimization, and manufacturing innovation together. The
state-of-the-art design activities are not necessarily an effective integration
between material and manufacturing itself. Therefore, this symposium brings
domain experts together to share experiences from materials design to
manufacturing innovation.
The symposium will include but not limited to the following topics:
(1) Alloy design theory and fundamentals of materials processing. This can be
either theoretical work related to materials genome or experimental efforts
such as high-throughput experiments.
(2) Materials informatics including database development for alloy
manufacturing such as thermodynamic modeling, phase transformation modeling,
and machine learning enhanced modeling of process-structure-property
relationships.
(3) Alloy development with the investigation on
composition-process-structure-property relationships. This will include but is
not limited to lightweight alloys, steels, superalloys, multi-principal element
alloys.
(4) Examples of harnessing advanced processing techniques to produce novel
microstructures or materials with unique properties.
(5) Processing optimization for both traditional and innovative manufacturing
techniques focusing on process-structure-property relationships.
(6) Interdisciplinary work in materials, mechanical, and manufacturing
engineering for advanced materials and manufacturing innovations.
Invited talks will cover the above topics. At least one session of invited
talks by young investigators will be arranged.

This symposium addresses synthesis, property measurements, phase stability,
phase transformation of the alloys and compounds used in the thermoelectric and
solar cell devices. Materials of interests include, but not limited to,
skutterudites, superlattice, half-heusler alloys, CdTe, CIS, CIGS, CZTS and new
materials for thermoelectric and solar cell applications. Abstracts are due by
July 1st, 2020. Please submit abstracts directly to TMS Online
(https://www.tms.org/tms2021).
In contrast to conventional alloys, which are based upon one principal element,
HEAs have multiple principal elements, often five or more. The significantly
high entropy of the solid solution can potentially stabilize the solid-solution
phases in face-centered-cubic (FCC), body-centered-cubic (BCC), and hexagonal
close-packed (HCP) structures against intermetallic compounds. Moreover,
carefully-designed HEAs possess tailorable properties that far-surpass their
conventional alloys. Such properties in HEAs include high strength, ductility,
corrosion resistance, oxidation resistance, fatigue and wear resistance. These
properties will undoubtedly make HEAs of interest for use in biomedical,
structural, mechanical, and energy applications. Given the novel and exciting
nature of HEAs, they are poised for significant growth, not unlike the bulk
metallic glass or nanostructured alloy scientific communities, and present a
perfect opportunity for a new symposium.
Topics of interest include but not limited to:
(1) Material fabrication and processing, such as homogenization, nanomaterials,
and grain-boundary engineering
(2) Advanced characterization, such as neutron scattering and three-dimensional
(3D) atom probe
(3) Thermodynamics and diffusivity: measurements and modeling
(4) Mechanical behavior, such as fatigue, creep, and fracture
(5) Corrosion, physical, magnetic, electric, thermal, coating, and biomedical
behavior
(6) Theoretical modeling and simulation using density functional theory,
molecular dynamics, Monte Carlo simulations, phase-field and finite-elements
method, and CALPHAD modeling
(7) Industrial applications
This symposium will be held in honor of the 2021 William Hume-Rothery Award
recipient, JC Zhao, in recognition of his development of groundbreaking
methodologies for systematic measurements of phase-based properties for the
understanding of a very large number of alloy systems. The goal of the
symposium is to assess the current state of the art in experimental
measurements and first-principles calculations of phase-based properties,
especially thermodynamic and kinetic properties, which are essential
information for computational alloy design and process optimization.
High-throughput experimental and computational methods are key for the timely
establishment of databases of phase-based properties for ICME (Integrated
Computational Materials Engineering). The close integration of experimental and
computational approaches, especially with the help of materials informatics and
machine learning (data analytics) tools, is becoming increasingly effective in
both database establishment and computational alloy design. One of the
awardee’s passions is industrial applications of novel methodologies and
databases in designing new alloys for real-world impact. This symposium will
provide an overview of the state-of-the-art methodologies for high-throughput
experimentation, accurate property predictions, integration of experimental and
computational approaches, and real-world applications of new tools for
materials design and discovery.
The presentations in this symposium are by invitation only.
The topics will cover:
Computational thermodynamics and diffusion kinetics.
High-throughput and accelerated experimentation
First-principles calculations of phase-based properties
Materials informatics and machine learning tools
Materials genome and ICME methods
Accelerated materials design for advanced manufacturing
This is the 20th in a series of TMS symposia addressing the stability,
transformation, and formation of phases during the fabrication, processing, and
utilization of electronic materials and devices. Topics of interests range from
microelectronic technologies to advanced energy technologies, including phase
stability, transformation, formation, and morphological evolution of electronic
packaging materials, interconnection materials, integrated circuit materials,
optoelectronic materials as well as energy storage and generating materials.
Growth in materials diversity for metals-based additive manufacturing (AM) is
becoming increasingly important due to the challenges associated with achieving
controllable microstructures and properties in technically relevant alloys,
such as conventional steels (i.e., 316L stainless steel), aluminum alloys such
those based on Al-Cu-Mg-Sc-Si, Ni-Cr–based superalloys (Inconel 718/625), and
titanium alloys (largely Ti-6Al-4V). There is an increasing need to develop new
materials feedstocks that are better suited to take advantage of AM processes
and their parameters. New alloys for structural and biomedical applications,
high-strength and high-radiation-resistant alloys, and hierarchically graded
materials, among others, have begun to generate interest.
This symposium will highlight recent advances in the design and optimization of
new alloy feedstock materials for AM. Presentations are sought that illustrate
paths toward broadening the design space to include new, innovative materials,
including but not limited to:
• New alloys for AM, such as high-entropy alloys
• Experiments that explore a broader alloy design space, including powder
development and microstructural assessments
• Combinatorial experimental approaches for materials design and optimization
• Computational methods for design of alloys with improved properties
• Experiments and simulations that aid in understanding the role of physical
properties on alloy design
• Advanced characterization techniques that provide insight for materials
design
This symposium will provide a new venue for presentation of research on the
fundamental understanding and theoretical modeling of high-entropy alloy (HEA)
processing, microstructures, and mechanical behavior.

(7) Industrial applications
This symposium will provide an opportunity for invited speakers from the
academia, industries, and governments to discuss the current interest and
progress in advanced structural and functional materials, including
bulk-metallic glasses (BMGs), high-entropy alloys (HEAs), etc. The symposium
is to honor Prof. Peter K. Liaw for his significant contributions to materials
science and engineering and TMS. The aim is to provide a mechanism for a group
of students, researchers, engineers, and administrators to promote idea
exchanges and advance the fundamentals and applications of materials science
and engineering. The process from the basic materials research to successful
applications will be examined. The symposium will have dedicated sessions that
emphasize processing, microstructures, and mechanical behavior of BMGs, HEAs,
etc. in which Prof. Liaw has made great contributions. Other sessions will
address fatigue and fracture behavior, theoretical modeling, and simulations of
structural materials. In-situ studies of microstructural and mechanical
damages during deformation will be included, such as neutron and synchrotron
diffraction, thermography, electron microscopy, acoustic emission, etc. This
symposium is via invitation only.
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 similar
topics are categorized in the same scope 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.

Computational methods have become essential tools for materials and process
development. The CALPHAD method has been known as one of the pillars of
integrated computational materials engineering among these tools because of its
focus on alloy systems that are of practical interest to industry. CALPHAD
calculations are being coupled to an array of process simulations, such as
solidification and phase field simulations. Today, CALPHAD databases are
available for thermochemical properties, diffusion mobilities and molar volume
and unite data from experimental measurements and atomistic simulations. The
focus of this symposium is to gain an overview of the state-of-the-art of
computational and experimental methods in the field of thermochemistry, phase
equilibria and kinetics of inorganic materials and application of the results
to solve engineering problems. The presentations in this symposium are invited
only.
