High entropy alloys, refractory high entropy alloys, methods of selecting and making, and structures formed thereof

DWPI Title: High entropy alloy used in e.g. gas-cooled very high temperature reactor, comprises chromium, manganese, niobium, titanium, zirconium, vanadium, and transition metal selected from nickel and iron
Abstract: The present disclosure is directed to novel high entropy alloys, including refractory high entropy alloys, and methods of selecting high entropy alloys and refractory high entropy alloys with select nuclear application predetermined properties.
Use: Refractory high entropy alloy for a gas-cooled very high temperature reactor (GC-VHTR), and used for a molten salt cooled VHTR.
Advantage: The alloy can withstand high radiation, corrosion, temperature, and pressure environments that are ideal for extending the performance of materials in high temperature applications, including current reactors, next-generation advanced, high-temperature reactors and renewable energies including concentrated solar power and smart-grids.
Novelty: Alloy comprises chromium iron manganese niobium zirconium and chromium-manganese-niobium-nickel zinc, where each element is in equiatomic or near-equiatomic amounts. The alloy consists of chromium, neodymium, titanium, zinc, or vanadium, and transition metal selected from nickel and iron. The refractory elements and the transition metal are in equal or near equiatomics. The transition metal is selected from the group consisting of nickel or iron.
