摘　　要：对ZL102合金的热处理工艺参数进行优化,采用力学性能检测、组织观察等方法对铝合金的性能和强化机制进行了研究。结果表明:该成分铝合金的最佳热处理工艺为:540℃×5 h固溶+200℃×5 h时效;经上述工艺热处理后,合金的布氏硬度为93.7 HB,抗拉强度为221.65 MPa。Taking ZL102 alloy as the research object, the heat-treatment parameters were optimized. The properties of AI alloy and strengthening mechanism were studied by mechanical property examination and organization observing. The results show that the best heat-treatment process is： solution at 540 ℃ for 5 h and then aging at 200℃ for 5 h. Under this heat treatment, the mechanical performance of the alloy is hardness 93.7 HB, tensile strength 221.65 MPa.
