摘　　要：研究了时效过程中同时通以直流电流条件下,ZL107合金组织和性能的变化规律,并对其相对应的机理进行探讨。结果表明,采用直流电流时,时效处理后的合金中CuAl2相的形状发生了明显改变;Cu在合金中的固溶度明显增加;同时,合金既保持了传统热处理后所能达的抗拉强度和硬度,又弥补了传统方法处理后合金在塑性上的不足,大大改善了ZL107合金的综合性能。The variation rules of microstructure and mechanical properties of the ZL107 alloy under direct current combined with aging were studied, and the corresponding mechanism was discussed. The results show that the shape of CuA12 phase changes greatly, and the solid solubility of Cu in the base increases obviously. The strength and hardness of the alloy show lesser amplitude, but the plasticity shows obvious amplitude, which can improve the integrated properties of the alloy.
