New approaches for the design of alloy systems with multiprincipal elementsis recently researched in refractory materials field. However, most researchaimed at arc melting process with weakness of coarsening of grains andinhomogeneous microstructure of segregation of elements during the cooling.This study aims to design and fabricate high-entropy alloy with powdermetallurgy. In this study, a refractory high entropy alloys with compositionnear AlMo0.5NbTa0.5TiZr were produced by powder metallurgy. The alloy consistsof two body-centered cubic (BCC) phases. One phase was disordered BCC enrichedwith Mo, Nb and Ta and the other phase was ordered BCC enriched with Al and Zr.The AlMo0.5NbTa0.5TiZr alloy had a density of 7.46g/cm3 and Vickersmicrohardness of 678HV. Its compressive yield strength was 2466MPa at 298K and964MPa at 1273K. The properties of the alloy and the beneficial effects frompowder metallurgy on the microstructure and properties were outlined.
