中文摘要:对热压缩变形的AZ91D镁合金进行T6热处理(410 ℃× 3 h固溶,分别在150、170、190 ℃时效16 h)。结果表明:T6热处理大大提高了合金的强度和硬度,但降低了塑性;190 ℃的时效强化效果较好。
英文摘要:T6 heat treatment of solution at 410 ℃ for 1 h, and aging at 150 ℃, 170 ℃, 190 ℃ for 16 h of AZ91D alloy after hot compression were carried out. The results show that the strength and hardness of the alloy improve largely by T6 treatment, but the deformability decreases. The better intensification effect can be obtained when aging at 190 ℃.
