Real time observations can provide important information needed to understand
materials behavior, as these techniques can provide temporal and spatial
insights free from artifacts otherwise induced from conventional experimental
techniques. Traditional and emerging advanced imaging techniques, which may be
optical or non-optical, would allow such observations. Methods may be enhanced
with capabilities that enable heating and cooling, controlled atmospheres, and
application of stresses; and can be used to generate real time thermodynamic
and kinetic data needed to study a variety of materials and processes. This
symposium encompasses a broad range of materials science topics enabling
cross-cutting opportunities for multiple disciplines (biomaterials, energy
materials, functional materials, structural materials, etc.) while topics will
be separately categorized in the technical program. Presentations are solicited
on the application of these methods to materials science and industrial
processes, as well as on development of such techniques.
Topics include, but not limited to:
• Studies using real time optical (e.g., visible light, white light, laser, IR,
and UV) and non-optical (e.g., scanning probe, electron, and ultrasound)
imaging techniques
• Researches using in-situ, in-operando, in-vitro, and in-vivo observation
imaging techniques, such as thermal imaging furnace and other real time imaging
methods
• Confocal techniques, including fluorescence and reflection types, which may
be equipped with capabilities such as heating/cooling chambers, gas chambers,
mechanical testing, Raman spectroscope, mass spectrometry, and FTIR
• Microscopic or telescopic imaging methods include hot thermocouple,
resistance heating, and sessile drop techniques used for high temperature
phenomena.
• Thermodynamic and kinetic data from these techniques, useful for phase
diagram constructions, oxidation/corrosion modeling, phase formation kinetics
studies, etc.
• Work using high speed and slow speed cameras
• Materials used in manufacturing real time imaging devices
• Novel technologies and methodologies for emerging imaging devices
The symposium plans the following joint sessions with:
• The Bio-Nano Interfaces and Engineering Applications symposium
• The Mechanical Response of Materials Investigated through Novel In-situ
Experiments and Modeling symposium
Respective papers may participate in part of the dedicated sessions.
This symposium provides an opportunity for scientists and engineers to present
and discuss the latest theoretical and applied research related to the
fabrication methods, microstructures, and mechanical behavior of high-entropy
alloys (HEAs) or multi-principal element alloys (MPEAs).
BACKGROUND AND RATIONALE: HEAs and MPEAs consist of five or more elements and
typically consist of body-center-cubic (BCC), face-centered-cubic (FCC), and
hexagonal-close-packed (HCP) solid-solutions phases. These material systems
possess many desirable properties, such as irradiation resistance, remarkable
corrosion and oxidation resistance, high strength and ductility, and high
fatigue/wear resistance. These positive characteristics therefore make
HEAs/MPEAs viable candidates for several applications, such as biomedical,
energy, mechanical, and aerospace industries.
Topics of interest include, but are not limited to:
(1) Theoretical modeling and simulation using advanced computational
techniques, including molecular dynamics, Monte Carlo, CALPHAD modeling,
density functional theory, phase-field modeling, finite-element techniques, and
machine learning methods
(2) Advanced in situ characterization methods, such as transmission electron
microscopy, neutron scattering, three-dimensional (3D) atom probe tomography,
and electron backscatter diffraction
(3) Material fabrication and processing techniques, including additive
manufacturing, grain-boundary engineering, and homogenization
(4) Mechanical behavior, such as creep, wear, fatigue, serrated plastic flow,
and fracture
(5) Microstructural modification and control that alter the various biomedical,
physical, mechanical, corrosion, magnetic, electric, irradiation, and thermal
behavior
(6) Diffusivity and thermodynamic phenomena
(7) Applications in the biomedical, automotive, aerospace, energy, and other
industries
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 interest include but are not limited to
skutterudites, superlattice, half-heusler alloys, CdTe, CIS, CIGS, CZTS, and
new materials for thermoelectric and solar cell applications.
This symposium will bring together experts in the application of first
principles calculations of complex and functional materials, to assess the
current state of the art in their application to ab-initio and data-driven
materials discovery and design. Topics will cover but not limited to high
throughput materials discovery, first principles-based phase diagram
constructions, thermodynamic and kinetic properties of multi-component
materials, and the use of ab-initio methods to understand the synthesis of
materials. It will survey recent progress in method and theory developments
that are driven by the materials genome initiatives, with a particular emphasis
on development of computational and machine-learning methods and autonomous
experimentation to guide materials synthesis, characterization, and new
functionality.
Sessions will include talks by experts in computational methods and
applications, as well as experimenting working at the forefront of data-driven
synthesis and characterization.
The session is by invitation only.
This symposium is to celebrate the impact of Professor Zi-Kui Liu on the fields
of computational materials science and materials design on the occasion of his
60th birthday, the 20th anniversary of Prof. Liu coining the term “Materials
Genome”, and the progress of computational thermodynamics (CALPHAD) in the last
50 years as the foundation of materials design.
To honor the broad range of Professor Liu’s research on metals, ceramics,
battery materials, and 2D materials, the symposium will highlight work that
integrates theory with computational and experimental investigations and that
utilizes a multidisciplinary approach. The symposium will focus on
thermodynamics with internal processes in terms of theory, prediction,
modeling, and applications. Consequently, this symposium welcomes contributions
from all these aspects, including but not limited to the following topics
• Theory of reversible and irreversible thermodynamics
• Development of computational tools for thermodynamics
• Determination of thermodynamic properties through density functional theory,
machine learning models, ab initio molecular dynamic simulations, and
experiments
• Thermodynamic modeling through the CALPHAD method and statistical mechanics
• Applications of thermodynamics for rational and inverse design of chemistry
and synthesis of materials, simulation of kinetic processes and deformation,
and understanding of complex phenomena.
This is the 22nd 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…)
- 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
