2018 TMS Annual Meeting & Exhibition: Refractory Metals 2018: 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. Presentations that communicate results from academia, national laboratories and industry are encouraged.

2017 TMS Annual Meeting & Exhibition: Materials for High Temperature Applications: Next Generation Superalloys and Beyond: Organized by Akane Suzuki; Martin Heilmaier; Pierre Sallot; Stephen Coryell; Joseph Licavoli; Govindarajan Muralidharan

Nickel-based superalloys possess excellent combination of mechanical properties and environmental resistance at elevated temperatures, and they have been widely used in challenging environments such as aircraft engines and land-based power generation gas turbines, as well as nuclear power and chemical plants. The ever-increasing demand for higher operating temperatures to achieve better fuel efficiency has been driving the development of the next generation of superalloys, in which the higher temperature capability has been achieved by increasing additions of refractory elements, optimizing processing conditions and application of coatings. However, there has been a strong need of materials that can make a significant change in temperature capability beyond Ni-base superalloys. Refractory metal-based alloys and refractory metal-based intermetallics have been recognized as strong candidate materials. The goals of this symposium are to discuss recent progress in development of high temperature material systems that can offer capabilities beyond Ni-base superalloys and to understand their latest status, entitlement and limitations, as well as to understand current challenges that Ni-base superalloys are facing. The 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, and (4) coatings.

2016 TMS Annual Meeting & Exhibition: Refractory Metals 2016: Organized by Gary Rozak; Eric Taleff; Ivi Smid

Refractory metal experts will gather for discussions and updating technical progress in advancing processing, testing, and applications of these materials in energy, transportation, and other systems. These systems demand structural materials that can maintain their stability, environmental resistance, and mechanical properties at the high temperatures driven by ongoing technological advancements. Refractory metals are defined by metallic elements with melting temperature above 1850�C.
