Abstract

Light weight high entropy alloy (TiZrV_0.5Nb_0.5)_99.4Si_0.6 with a density of 6.1 g/cm³ was prepared by vacuum arc melting. The effects of different hot-rolling temperatures (900℃, 1000℃ and 1100℃) on the microstructure and mechanical properties were investigated. The results show that after rolling, the strength and elongation are both improved. The tensile strength and elongation of the alloy with a rolling temperature of 900℃ reached 1164.5 MPa and 14.7%, which was best and can surpass 13.9% and 950% than that of the as-cast alloy respectively. However, with the further increase of hot-rolling temperature, the grain size increases and the mechanical properties decline. The excellent mechanical properties of the alloy with a rolling temperature of 900℃ are the result of dislocation, solid solution, second phase and grain refinement.
