摘　　要：利用JMatpro模拟软件研究了Si、Cu、Mg元素对电力金具ZL111电导率及力学性能的影响。并根据电力金具的使用性能,以高硅低铜低镁合金成分为基础,研究了在不同成型方式下固溶温度、时效温度对ZL111强度的影响。研究结果表明:随着Si、Cu含量的升高,合金的电导率降低,随着Mg含量的升高,合金的电导率升高;合金的屈服强度随着Si、Cu、Mg含量的升高而升高;合金的抗拉强度随着Si含量的升高而升高,随着Cu、Mg含量的升高而降低;合金的硬度随着Si含量的升高而降低,随着Cu、Mg含量的升高而升高。不同成型方式下固溶温度及时效温度对合金的强度影响程度不同,当固溶温度为540℃,时效温度为150℃时,无论采用哪种成型方式,合金的强度都为该成型方式下的最大值。The effects of Si,Cu and Mg elements on the conductivity and mechanical properties of ZL111 were studied by using JMatpro simulation software,and the effects of solution temperature and aging temperature on the strength of ZL111 under different molding methods were studied based on the performance of power fittings and based on the composition of high-silicon,low-copper and lowmagnesium alloys.The results show that the conductivity of the alloy decreases with the increase of Si and Cu contents,and increases with the increase of Mg content.The yield strength of the alloy increases with the increase of Si,Cu and Mg contents.The tensile strength of the alloy increases with the increase of Si content,and decreases with the increase of Cu and Mg content.The hardness of the alloy decreases with the increase of Si content,and increases with the increase of Cu and Mg contents.When the solution temperature is 540℃and the aging temperature is 150℃,the strength of the alloy is the maximum value under the molding method,no matter which molding method is used.
