Abstract

The tensile property of Al_0.5CoCrFeNi high entropy alloys heat-treated at 650 °C for 0.5–8 h respectively was executed. The yield strength and ultimate tensile strength reached to 834 MPa, 1220 MPa for 650 °C/8 h heat-treated condition, which was attributed to the nano-sized B2 phase in the interdendritic region and precipitates in the dendritic region.
