摘要(Abstract)：

采用金属型铸造法制备了Zn-4Al-2Cu-0.5Mg-0.1Y锌合金。采用光学显微镜、扫描电镜、X射线衍射仪和显微硬度仪等研究了时效温度对其微观组织、力学性能和导电率的影响。结果表明:铸态锌合金组织主要由η(Zn)固溶体和共晶体结构η(Zn)+α(Al)组成;时效温度为140℃时,锌合金的拉伸强度达到最大,为263 MPa,时效温度为160℃时,其导电率最高,为23.28%IACS,时效温度在180℃时,其硬度最大,为148.7 HV。锌合金的磨损机制为塑性变形和粘着磨损的混合,拉伸断裂机制为解离断裂。

关键词(KeyWords)： 锌合金;时效温度;导电率;拉伸强度
