摘　　要：通过试验研究了工艺参数和热处理对挤压铸造AZ91D合金力学性能的影响。结果表明:合理的工艺参数使AZ91D合金在普通冷室压铸机条件下可以获得良好的力学性能。且经固溶处理后其抗拉强度、硬度和伸长率都会提高,而经固溶时效处理后抗拉强度和硬度会进一步提高,但伸长率有所下降。The effects of the process parameters and the heat treatment on the squeeze casting AZ91D alloy＇s mechanical properties were researched by experiments. The result shows that the suitable process parameters make AZ91D alloy gain the good mechanical properties under the common squeeze casting machine cooled in the room temperature. And the tensile strength, hardness and elongation of alloy are improved by the solution, even the tensile strength and hardness are dramatically increased, but the elongation decreases somewhat.
