Scope The refractory metals W, Re, Ta, Mo, and Nb have extremely high melting temperatures, from 2468 up to 3180C. Alloy systems based on these elements are of renewed interest in designing new alloys for ultra-high temperature applications. Barriers that must be overcome in designing and implementing new refractory-metal-based alloys suitable for ultra-high temperature service include: maintaining high melting temperatures in a multicomponent systems, effectively using strengthening mechanisms at very high temperatures, dealing with poor oxidation resistance, and avoiding problems with corrosion. This symposium offers a venue to communicate research addressing these barriers and other issues related to the design, testing, manufacturing, and implementation of refractory metal alloys in ultra-high temperature applications. We encourage both experimental and theoretical work from academic, government, and industrial sectors to promote a diverse group of presentations from professionals and students.
