2022 TMS Annual Meeting & Exhibition: Refractory Metals: Organized by Eric Taleff; Lauren Garrison; Alexander Knowles

This symposium provides a forum for the presentation of fundamental research advances and technological progress in the understanding, processing, and applications of refractory metals. Refractory metals are defined as those metallic elements with melting temperatures in excess of 2123 K (1850�C). Refractory metals are of technological importance for their resistance to extreme high temperatures and extreme environments. Research of interest includes alloy development, microstructure evolution, and correlations with properties, both experimental and theoretical. Technological advances in processing of refractory metals and their alloys and applications in energy generation, nuclear fusion, transportation, space and other sectors are likewise of interest. New developments of interest include composite materials based on refractory metals, such as silicide alloys or composites between refractory and non-refractory metals, and other related alloy systems. Processing methodologies and techniques involving welding, brazing and powder metallurgy are also of interest. Presentations that communicate results from academia, national laboratories, and industry are welcomed.

2021 TMS Annual Meeting & Exhibition: Materials for High Temperature Applications: Next Generation Superalloys and Beyond: Organized by Govindarajan Muralidharan; Martin Heilmaier; Benjamin Adam; Mario Bochiechio; Katerina Christofidou; Eric Lass; Jeremy Rame; Sallot Pierre; Akane Suzuki; Michael Titus

Nickel-based superalloys possess an excellent combination of high temperature mechanical properties and environmental resistance, resulting in their wide-spread use in challenging environments found in aircraft engines, land-based power generation gas turbines, nuclear power generation systems, and chemical/petrochemical plants. However, there is a strong need of materials that can enable a revolutionary increase in temperature capability beyond these Ni-base superalloys. Refractory metal-based alloys and refractory metal-based intermetallics are examples of such candidate materials. The goals of this symposium are to discuss recent progress in the development of high temperature material systems that can offer capabilities beyond current Ni-base superalloys and to understand their status, entitlement and limitations, as well as to understand challenges in the use and development of advanced Ni-base superalloys. Topics for discussion include thermodynamics, microstructural design and long term stability, processing, physical properties, mechanical behavior, and environmental resistance of (1) current and next generation Ni-base superalloys, (2) refractory metal based materials, (3) intermetallic based materials, (4) High Entropy/Compositionally complex/Multi-principal element alloys, and (5) coatings.

2019 TMS Annual Meeting & Exhibition: Refractory Metals 2019: Organized by Eric Taleff; Martin Heilmaier; Kevin Jaansalu

This symposium provides a forum for the presentation of fundamental research advances and technological progress in the understanding, processing and applications of refractory metals. Refractory metals are generally defined as those metallic elements with melting temperatures in excess of 2123 K (1850 � C). Refractory metals are of technological importance for their resistance to extreme high temperatures and difficult environments. Research of interest includes alloy development, microstructure evolution and correlations with properties, both experimental and theoretical. Technological advances in processing of refractory metals and their alloys and applications in energy, transportation and other sectors are likewise of interest. New alloy developments of interest include composite materials based on refractory metals, such as silicide alloys, and concentrated solid solution (high-entropy) alloys. Processing methodologies and techniques involving welding, brazing and powder metallurgy are also of interest. Presentations that communicate results from academia, national laboratories and industry are encouraged.
