2022 TMS Annual Meeting & Exhibition: Algorithm Development in Materials Science and Engineering: Organized by Mohsen Asle Zaeem; Mikhail Mendelev; Garritt Tucker; Ebrahim Asadi; Bryan Wong; Samuel Reeve; Enrique Martinez Saez; Adrian Sabau

As computational methodologies in the materials science and engineering become more mature, it is critical to develop, improve, and validate techniques and algorithms that leverage ever-expanding computational resources. These physical-based and data-intensive algorithms can impact areas such as: data acquisition and analysis from sophisticated microscopes and state-of-the-art light source facilities, analysis and extraction of quantitative metrics from numerical simulations of materials behavior, and implementation on novel peta- and exascale computer architectures for revolutionary improvements in simulation analysis time, power, and capability. This symposium solicits abstract submissions from researchers who are developing new algorithms and/or designing new methods for performing computational research in materials science and engineering. Validation studies and uncertainty quantification of computational methodologies are equally of interest. Session topics include, but are not limited to: • Advancements that enhance modeling and simulation techniques such as density functional theory, molecular dynamics, Monte Carlo simulation, dislocation dynamics, electronic-excited states, phase-field modeling, CALPHAD, and finite element analysis; • Advancements in semi-empirical models and machine learning algorithms for interatomic interactions; • New techniques for simulating the complex behavior of materials at different length and time scales; • Computational methods for analyzing results from simulations of materials phenomena; • Approaches for data mining, machine learning, image processing, high throughput databases, high throughput experiments, and extracting useful insights from large data sets of numerical and experimental results; • Approaches for improving performance and/or scalability, particularly on new and emerging hardware (e.g. GPUs), and other high-performance computing (HPC) efforts; and • Uncertainty quantification, model comparisons and validation studies related to novel algorithms and/or methods in computational material science.

2022 TMS Annual Meeting & Exhibition: Defects and Properties of Cast Metals IV: Organized by Lang Yuan; Brian Thomas; Peter Lee; Mark Jolly; Alex Plotkowski; Andrew Kao; Kyle Fezi

Defects generated during the solidification of liquid metals, whether during primary metal processing, shape casting or additive manufacturing, dramatically affect the subsequent mechanical and physical properties of the final product. These defects arise from a range of fundamental mechanisms such as surface oxidation, entrainment of exogenous materials, dissolved gasses, solidification shrinkage, unwanted micro-structural phases with detrimental morphologies and the development of stresses in the solidifying metal resulting in hot tearing and cracking. In many instances, defects arise from a combination of many physical processes. This symposium seeks contributions from all alloys systems, including ferrous, non-ferrous, superalloys, and other materials; and from all metals processes, including: ingot casting, DC casting, foundry/shape casting, die casting, investment casting, sand casting, continuous casting, and advanced solidification processes, such as additive manufacturing involving molten metal. Topics include measurements and modeling of any phenomena related to casting defects and properties: liquid metal refining, inclusions and metal cleanliness; re-oxidation; slag / dross entrainment and fluid flow effects; surface defects, shrinkage, gas, and porosity problems; segregation (a-, v-, freckles, inverse, centerline, etc.); hot tearing and other cracks; residual stresses, distortion, and shape problems; microstructural, precipitate- and grain defects in the present of or without external fields, e.g. ultrasound, electromagnetic, shearing, etc; in-service properties, such as strength, ductility, toughness, fatigue, and wear; advanced characterization methods for defect detection, both online and ex situ sampling methods and modeling. The objective is to bring together researchers working in diverse fields that may share common fundamentals and goals, but may not usually collaborate, in order to stimulate interdisciplinary discussion. This is the 4th International Symposium on Defects and Properties in Cast Metals sponsored by the Solidification Committee of the TMS MPMD.

2021 TMS Annual Meeting & Exhibition: Additive Manufacturing of Metals: Applications of Solidification Fundamentals: Organized by Alex Plotkowski; Lang Yuan; Kevin Chaput; Mohsen Asle Zaeem; Wenda Tan; Lianyi Chen

Additive manufacturing is a disruptive technology, offering increased part complexity, short lead times, and opportunities for local microstructure control. Microstructure and defect development in AM processes is influenced by solidification and melt pool dynamics, but currently the application of fundamental solidification theories to AM process conditions has not been fully explored. Furthermore, increased demand for customized material properties and localized microstructure control will inevitably require a detailed understanding of solidification in these processes. The goal of this symposium is to highlight research in metal additive manufacturing that applies fundamental solidification theory to understand and solve contemporary processing challenges. This symposium will inform the solidification community about the unique characteristics of AM and guide the AM community to recognize the parallels that exist in the welding and solidification literature. Both experimental and modeling submissions are encouraged, especially in which modeling or theory is connected to experimental results or in situ characterization, as well as the use of data analytics and machine learning approaches to building process-structure-property relationships. The symposium will consist of 4 total sessions.

The eighth “Frontiers in Solidification" symposium will provide a forum to present and discuss the latest advances in the field of Solidification Science. The main focus will be on the fundamental aspects of solidification, with the aim of advancing our understanding of how microstructures develop and evolve during solidification experiments or processes. Beyond solidification, contributions that investigate melting phenomena are also encouraged.
