摘要：As-cast AlCrFeNi<inf>2</inf>Ti<inf>0.5</inf>high entropy alloy was annealed at 600 C and 800 C for 6 h, 12 h and 24 h, respectively. The effect of annealing time on the microstructure and mechanical properties were investigated intensively. The as-cast sample showed a fine and homogeneous microstructure, and owned an excellent ductility of 16.3%. While the 600 , 12 h annealed sample showed the highest compressive strength of 2658 MPa and yield strength of 2046 MPa. The mechanical properties of the samples after 800 C annealed for 12 h and 24 h deteriorated obviously. High annealing temperature promotes the growth of the crystal grains, and the new generated FeCr-type intermetallic phase leads to the embrittlement of the alloy. ?
