摘　　要：研究了稀土钇的添加量对Cu-Fe-P合金的显微组织、导电性、抗拉强度、硬度等性能的影响。研究结果表明,在合金中加入稀土钇能起净化的作用,从而改善铜合金的导电性能;也可细化晶粒,改善合金的抗拉强度等力学性能。在实验条件下,稀土钇的最佳添加量为0.06%。The effect of addition of yttrium on microstructure, electrical conductivity, tensile strength and hardness of Cu-Fe-P alloy were investigated. The results indicate that yttrium can purify the alloy thereby improve on the electrical conductivity, refine the grain and increase the tensile strength or other mechanical properties. The optimal content of yttrium in the alloy is 0.02% under the experimental condition.
