The refractory metals W, Re, Ta, Mo, and Nb have extremely high melting temperatures, from 2468 up to 3180°C. 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. |
