The crystal structure, microstructure, density and compression properties of a novel AlNbTiVZr0.5 high entropy alloy are reported. After homogenization the alloy is composed of bcc matrix phase containing Laves and Zr2Al-type second phase particles. The alloy has low density of 5.64gcm−3. The yield strength of the alloy gradually decreases from 1430MPa at room temperature to 680MPa at 800°C and drops to 75MPa at 1000°C. The alloy can be compressed to 50% height reduction without fracture at temperatures from room to 1000°C. Surface cracking is observed only at room temperature. The specific yield strength and ductility of the AlNbTiVZr0.5 alloy is compared with properties of other high entropy alloys intended for high-temperature usage.
