摘　　要：研究得出Ag_(41)Cu_(42)Sn_(17-x)In_x合金以α-Ag相和β-Cu相这两种固溶相为主,枝晶间分部着少量的铜锡中间化合物,随着In含量的增加,合金中的β-Cu的生长受到抑制而共晶组织得以生长,合金中脆硬相逐渐分布均匀,枝晶间塑韧性较好的共晶组织逐渐增多导致合金的变形率逐渐增加,其中Ag_(41)Cu_(42)Sn7.4In9.6具有最高变形率37.2%。而合金中β-Cu相和枝晶间相的维氏硬度随着In含量的增加均表现出增大→减小→增大的规律。The research showed that the alloy of Ag41Cu42Sn（ 17 -x） Inx mainly contained α -Ag phase and α - Cu phase. Interdendritic was distributed with a small amount of copper and tin intermediate compounds. The growth of the β - Cu phase was restrained and the eutectic organization grew with the increase of the Indium. Brittle phase in the alloy were uniform distributed gradually, eutectic microstructure with good plasticity and toughness were increasing that led to alloy deformation rate increase. The alloy of Ag41Cu42Sn7. 4In9. 6 are the highest deformation rate with 37.2%. The vickers hardness of β - Cu phase and interdendritic phase in the alloy were shown the rule from increase to decrease then increase with the increase of the content of the Indium.
