- •
Novel AlNbTiVZr0.5 high entropy alloy was prepared by vacuum arc melting.
- •
The alloy is composed of bcc matrix and Laves and Zr2Al-type second phase particles.
- •
The density of the AlNbTiVZr0.5 alloy is 5.64 g cm−3.
- •
The alloy has high strength and compression ductility of 50% at room temperature.
- •
The AlNbTiVZr0.5 alloy preserves high specific strength at temperatures of ≤800 °C.
