2018 TMS Annual Meeting & Exhibition: Additive Manufacturing: Building the Pathway towards Process and Material Qualification : Organized by John Carpenter; Allison Beese; David Bourell; Christian Leinenbach; James Sears; Christopher Tuck

This symposium will provide a forum for all veins of additive manufacturing to present their latest results in developing methodology for science-based or practice-based material and process qualification. Sessions will be included that seek to develop processing-microstructure-property- performance relationships in metals and non-metals alike. Experimental, modeling, and combined experimental/modeling approaches are welcome. Background and Rationale: Additive manufacturing (AM) offers distinct advantages over conventional manufacturing processes including the capability to both build and repair complex part shapes; to integrate and consolidate parts and thus overcome joining concerns; and to locally tailor material compositions as well as properties. A variety of fields such as aerospace, military, automotive, and biomedical are employing this manufacturing technique as a way to decrease costs, increase manufacturing agility, and explore novel geometry/functionalities. To increase acceptance of AM as a viable processing method, pathways for qualifying both the material and the process need to be developed and, perhaps, standardized. This symposium will serve as a venue for the international AM community - including government, academia, and industry - to define the fundamental interrelationships between feedstock, processing, microstructure, shape, mechanical behavior/materials properties, and function/performance. This will be accomplished through experimental observations, theoretical advances, and computational modeling of physical processes to provide insight and understanding of the nature of the final product and the evolution of microstructure resulting in final part properties and performance. Materials of interest include but are not limited to: - Homogeneous materials: polymers, ceramics, and metals - Heterogeneous materials: foams, polymeric matrix, metallic matrix, ceramic matrix, functionally graded Areas of interest include, but are not limited to: - Fabrication: * Machines: emerging technologies and advancing current capabilities * Processing: feedstock material (including powder, wire, and filament), process and process monitoring (both freeform and direct write), build parameters, repair parameters, post processing (e.g., heat treatment) * Specimen design: net-shaped parts; parts machined to shape based on scaling; as built laboratory test specimens/coupons; specimens/coupons machined from larger builds - Developing constitutive relationships: coupling microstructure measurements and experimental stress analysis to characterize mechanical behavior/materials properties targeting performance - Closing the feedback loop: microstructure measurements feedback to fabrication; performance (mechanical behavior, materials properties, and/or functional) feedback to fabrication

2018 TMS Annual Meeting & Exhibition: CFD Modeling and Simulation in Materials Processing : Organized by Laurentiu Nastac; Koulis Pericleous; Adrian Sabau; Lifeng Zhang; Brian Thomas

This symposium deals with computational fluid dynamics (CFD) modeling and simulation of engineering processes. Papers are requested from researchers and engineers involved in the modeling of multiscale and multiphase phenomena in material processing systems. The symposium focuses on the CFD modeling and simulation of metal processes including continuous casting of alloys, electromagnetic stirring (EMS) and ultrasonic cavitation and stirring (UST) processing, controlled solidification processes, casting, forging, welding, heat treating, and VAR/ESR/PAM/EBM remelting processes; manufacturing of advanced metal-matrix-composites and nanocomposites via controlled melting and solidification processing, powder metallurgy, coatings including PVD, CVD, and plasma-assisted EBM-PVD technologies; and other surface and/or additive engineering processes including induction, ultrasonic, laser, and EB thermal processing. The symposium also deals with applications of CFD to engineering processes and demonstrates how CFD can help scientists and engineers to better understand the fundamentals of engineering processes.

2016 TMS Annual Meeting & Exhibition: Frontiers in Solidification: An MPMD Symposium in Honor of Michel Rappaz: Organized by Wilfried Kurz; Jon Dantzig; Alain Karma; Jeffrey Hoyt

This symposium follows the now well established symposium series “Frontiers in Solidification”. It is intended to present latest results of modeling of solidification microstructures such as solid liquid interfaces and their anisotropies, nucleation phenomena, morphological instabilities, dendrites, eutectics, peritectics, fluid flow effects, segregation and defects. The main objective of this symposium is to present research results from the interface between phenomena at different length scales (atomistic, microscopic, macroscopic), and from theoretical physics to industrial solutions, all using various theoretical approaches. In order to verify the results of the models, quantitative experiments are essential and will represent an important part of the presentations. Symposium mostly by invitation, poster presentations welcome.

2016 TMS Annual Meeting & Exhibition: Thermodynamic Applications, Optimizations and Simulations in High-Temperature Processes: An EPD Symposium in Honor of Christopher W. Bale's 70th Birthday: Organized by In-Ho Jung; Arthur Pelton; Patrice Chartrand; Phillip Mackey; David Robertson; Pekka Taskinen; Malin Selleby

A thermodynamic analysis of high temperature industrial processes is essential to understanding the complex chemical equilibria involved, to improving the performance of existing processes and to developing new processes. Major advances in thermodynamic software and the development of large evaluated optimized databases have made it possible to carry out such analyses and process optimizations efficiently in terms of both time and cost. Professor Christopher Bale has devoted his entire career to the development of “FactSage” which is one of the thermodynamic software/database packages used widely in high temperature processes, and to the education of the industrial and academic communities in the applications of thermodynamic calculations to industrial high temperature processes. In this Symposium, papers are invited on applications of thermodynamic software and databases such as FactSage, HSC Chemistry, MTData, Thermo-Calc, Pandat etc. to high temperature processes. Papers on experimental thermodynamic studies are also welcome. Contributions are solicited in, but not limited to, the following areas: - Pyrometallurgical Processing fundamentals: Ferrous and non-ferrous metallurgy - Process simulation - Refractories, Ceramics and Glasses; Combustion and Energy; Solidification; High temperature corrosion - Nuclear and other applications - Recycling and environmental engineering This symposium will be a prestigious event, expected to attract industrial and academic leaders in the field of high temperature processes: stimulating discussion; facilitating industry networking; attracting large and knowledgeable audiences.
