Abstract Low-density TiAlVNbMo refractory high-entropy alloys (RHEAs) with a single disordered BCC phase were prepared. Comparing with reported RHEAs and typical Nickel-based superalloys, the novel RHEAs exhibit significantly reduced density (∼6 g/cm3) and possess both high strength and good plasticity at temperatures up to 1000 °C.
