2023 TMS Annual Meeting & Exhibition: Advanced Real Time Imaging: Organized by Jinichiro Nakano; David Alman; Il Sohn; Hiroyuki Shibata; Antoine Allanore; Noritaka Saito; Anna Nakano; Zuotai Zhang; Candan Tamerler; Bryan Webler; Wangzhong Mu; David Veysset; Pranjal Nautiyal

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.

2023 TMS Annual Meeting & Exhibition: Advances in Multi-Principal Element Alloys II: Organized by Peter Liaw; Michael Gao; E-Wen Huang; Jennifer Carter; Srivatsan Tirumalai; Xie Xie; James Brechtl; Gongyao Wang

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 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.

2023 TMS Annual Meeting & Exhibition: Simulations/Experiments Integration for Next Generation Hypersonic Materials: Organized by Thomas Voisin; Jibril Shittu; Aurelien Perron; Joseph McKeown; Raymundo Arroyave

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
