Abstract
A novel lightweight high-entropy alloy Al2NbTi3V2Zr was fabricated by vacuum hot pressing. The effects of sintering temperature (1200–1550°C) on the microstructure, hardness and corrosion resistance of the alloy were investigated. Results showed that Al2NbTi3V2Zr mainly consisted of simple cubic matrix and (Zr, Al)-based intermetallic phase (α-phase) at sintering temperatures of 1200–1350°C. Moreover, the matrix phase transformed from simple cubic to body-centred cubic phase, and (Ti, Zr, Al)-based intermetallic precipitated from the matrix at temperature of 1450°C. The fabricated Al2NbTi3V2Zr alloy had low density of 5.05–5.23 g cm–3, high hardness of 510–728 HV and excellent corrosion resistance in 10 wt-% HNO3 solution.
