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 (similar to 6 g/cm(3)) and possess both high strength and good plasticity at temperatures up to 1000 degrees C.
