2022 TMS Annual Meeting & Exhibition: Materials Design and Processing Optimization for Advanced Manufacturing: from Fundamentals to Application: Organized by Wei Xiong; Dana Frankel; Gregory Olson

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.

2021 TMS Annual Meeting & Exhibition: High Entropy Alloys IX: Alloy Development and Properties: Organized by Peter Liaw; Michael Gao; E-Wen Huang; Srivatsan Tirumalai; Xie Xie; Gongyao Wang

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

2021 TMS Annual Meeting & Exhibition: Hume-Rothery Symposium: Accelerated Measurements and Predictions of Thermodynamics and Kinetics for Materials Design and Discovery: Organized by Wei Xiong; Shuanglin Chen; Wei Chen; James Saal; Greta Lindwall

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

2018 TMS Annual Meeting & Exhibition: High Entropy Alloys VI: Organized by Peter Liaw; Michael Gao; Xie Xie; Gongyao Wang; E-Wen Huang; T.S. Srivatsan

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. 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 stabilizes 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

2018 TMS Annual Meeting & Exhibition: Hume-Rothery Award Symposium: Computational Thermodynamics and Its Implications to Kinetics, Properties, and Materials Design: Organized by Suveen Mathaudhu; Michael Gao; Chelsey Hargather; Richard Hennig; James Saal; Dongwon Shin

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.
