A single-phase bcc high-entropy alloy in the refractory Zr-Nb-Ti-V-Hf system
, 2018 We report on the production and characterization of a high-entropy alloy in the refractory Zr-Nb-Ti-V-Hf system. Equiatomic ingots were produced by arc and levitation melting, and were subsequently homogenized by high-temperature annealing. We obtained a
