A light-weight refractory Al0.1CrNbVMo high entropy alloy (HEA) was fabricated by high energy ball milling and spark plasma sintering (SPS). The alloy had a density of 7.96 g/cm3, which is lower than that of conventional Ni-base superalloys. Optimum milling time was decided by the microstructure ana...
