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 symposium will offer the opportunities for discussions and presentations
on the current research regarding the experimental and theoretical studies on
the mechanical behavior, microstructures, and fabrication of multi-principal
elements alloys (MPEAs) or high-entropy alloys (HEAs).
BACKGROUND AND RATIONALE: MPEAs, which often consist of five or more elements,
typically consist of solid-solution phases in the form of face-centered-cubic
(FCC), body-center-cubic (BCC), and hexagonal close-packed (HCP) structures.
MPEAs possess desirable properties, including excellent ductility, exceptional
corrosion and oxidation resistance, irradiation stability, high strength,
fatigue and wear resistance. These aspects make MPEAs potential candidates for
use in structural, energy, mechanical, and biomedical fields. Furthermore,
recent research has suggested that there is potential for the development of
novel MPEAs with functional properties that far exceed those of conventional
materials.
Topics of interest include but not limited to:
(1) Mechanical behavior, such as plastic deformation, creep, fatigue, and
fracture
(2) Metastable MPEAs
(3) Microstructural control of material behavior (i.e., physical, mechanical,
corrosion, magnetic electric, irradiation, thermal, and biomedical behavior,
etc.)
(4) Material fabrication and processing, such as homogenization, nanomaterials,
additive manufacturing, and grain-boundary engineering
(5) Theoretical modeling and simulation using advanced computational
techniques, such as CALPHAD modeling, molecular dynamics, density functional
theory, Monte Carlo, as well as phase-field and finite-elements methods
(6) Advanced characterization methods, including in situ transmission electron
microscopy, neutron scattering, electron backscatter diffraction, and
three-dimensional (3D) atom probe,
(7) Thermodynamics and diffusivity: measurements and modeling, and
(8) Industrial applications
This Symposium focuses on the alloy design, development, and mechanical and
other properties of MPEA.
This symposium addresses synthesis, transport property, 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, 2022. Please submit abstracts directly to TMS Online
(https://www.tms.org/tms2022).
This symposium will bring together experts in first-principles statistical
mechanics, continuum modeling and advanced experimental characterization to
assess the current state of the art in multi-scale descriptions of
thermo-kinetic phenomena as they relate to equilibrium and non-equilibrium
properties of materials. It will survey recent progress in methods that connect
phenomenological theories of materials to their underlying electronic and
crystal structures, with a particular focus on phase stability, phase
transformations and the effect of chemistry and temperature on mechanical
properties. The symposium will combine treatments of computational approaches
spanning multiple length scales and experimental techniques to characterize
structure and non-equilibrium evolution. Specific topics will include phase
stability, diffusion, structural transformations, chemo-mechanics during
diffusional phase transformations and phase transformations in highly
anisotropic and low-dimensional systems.
Sessions will cover materials theory, computation and experiment as applied in
fundamental studies of structural and functional materials.
The session is by invitation only.
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 is the 21st in a series of TMS symposia addressing the stability,
transformation, and formation of phases during the fabrication, processing, and

packaging materials, interconnection materials, integrated circuit materials,
optoelectronic materials as well as energy storage and generating materials.

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.

method, and CALPHAD modeling
(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.

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

calculations, advanced experimental characterization and thermochemistry
methods, and CALPHAD modeling to assess the current state of the art as it
relates to complex materials. Of special interest will be strategies for
making links across these areas, to enable advanced fundamental understanding
and accurate modeling of materials with multicomponent chemistries and
disordered structures. Six sessions are planned, covering topics of bulk and
interfacial thermodynamic and chemical properties, in alloys, complex oxides
and related structural and functional materials. The session is by invitation

ICME has been marked as the essential method for materials discovery and
design, which promotes the materials innovations in engineering applications.
After ten years of ICME concept published by National Research Council, it is
worth reviewing the ICME education efforts that have been made at universities,
national labs and industry. The symposium provides a platform to share
experience of different universities and companies, who have put a considerable
amount of efforts in the past on ICME education. This mini-symposium will be

educators in the field of ICME research. It is expected that such a
mini-symposium will stimulate more ideas for the ICME education at different
educational levels.
The topics cover but not limited to: (1) undergraduate education program; (2)
graduate research related to ICME; (3) outreach of ICME, including industrial
education; (4) Software development for the ICME educational purposes. A panel
discussion session will be arranged to encourage more interactions between
speakers and audiences with stimulated thoughts/ideas.

(7) Industrial applications
Thermodynamics is a science concerning the state of a system when interacting
with the surroundings. Computational thermodynamics enables quantitative
calculations of thermodynamic properties as a function of both external
conditions and internal configurations and empowers the new materials research
paradigm of integrated computational prediction and experimental validation
approaches. The central constituent of computational thermodynamics is the
modeling of the thermodynamic description of individual phases in the complete
space of external and internal degrees of freedom. Over the past 40 years, the
CALPHAD modeling of thermodynamics has proven to be a successful approach
applicable to complex multicomponent materials. Integration with
first-principles calculations based on density functional theory, which is
capable of predicting electronic structures of atomic interactions, have
further significantly enhanced the efficiency and robustness of thermodynamic
modeling.
Computational thermodynamics plays a central role in materials design,
integrated computational materials engineering (ICME), and the Materials Genome
Initiative (MGI). Two important contributions of computational thermodynamics
are to predict the phase stability of a system under given conditions and
provide driving forces for internal processes in a system so the evolution of
such internal processes can be quantitatively simulated. Furthermore, as first
and second derivatives of the free energy with respect to system variables,
many physical properties can be calculated such as thermal expansion and
elastic properties. Additionally, through the mapping of the energy landscape
in the framework of computational thermodynamics, a broad range of properties
can be predicted and modeled such as diffusion coefficients, interfacial
energy, and dislocation mobility. Applications of these new capabilities
include improvements in the understanding of atomic interactions and the role
of alloy elements and trace additions on phase stability and phase
transformation behavior; improvement of existing materials for enhanced
performance; and the design and development of new materials for an optimal
combination of properties.
The focus of this symposium is to assess the state of the art in computational
thermodynamics for predictions and modeling capabilities and to identify the
key steps needed to make further progress. Abstracts are invited which
contribute to the above themes with critical appraisals of the strengths and
weaknesses of various approaches for specific properties and applications.
Case studies involving the use of computational thermodynamics to study
practical problems are welcomed along with studies involving both advanced
experimental work and state-of-the-art modeling approaches.
Submission of abstracts to the Hume-Rothery Symposium is by invitation only.
This is the 17th 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.
