摘　　要：在普通ZL107合金中添加0．15％Mg、0．15％Ti、0．15％Cd和1.0％Zn并通过适当热处理后合金的综合力学性能得到显著改善。实验结果表明，舍金成分经优化设计后，力学性能指标为：抗拉强度达361MPa，伸长率达3．65％。采用的515℃固溶处理加150℃时效处理，可使合金的组织细化，得到较好的强韧性配合。在合金中添加0．5％Ag可显著提高伸长率。The mechanical properties of ZL107 alloy can be markedly improved by the alloy elements of 0. 15%Mg,0. 15%Ti,0. 15% Cd and 1.0%Zn and appropriate heat treatment. Results show that the tensile strength and the rate of elongation are 361Mpa and 3.65% respectively. The fine rnicrostructure, good strength and toughness can be obtained by the process of 515℃ solute treatment and 150℃ aging. It also shows that the rate of elongation of the alloy has a great increase by adding 0. 15%Ag.
