Abstract:The mechanical properties, microstructure and impact property of Ti-6Al-3Nb-2Zr-1Mo alloy plate with thickness of 10 mm after annealing at 800, 840, 880, 920 and 1 040 ℃ were studied. The results show that the best annealing schedule is (880−920 ℃, 1 h, AC), in order to ensure the high comprehensive performance of Ti-6321 alloy.
