| 摘 要： | 加入适量的稀土元素能有效改善铜合金的组织和性能.铸态Cu-3.0Si-2.0Ni合金中添加稀土Ce后，进行熔炼及热处理试验，再通过室温拉伸、导电率试验和金相观察，研究了微量Ce对铸态Cu-3.0Si-2.0Ni合金组织与性能的影响.结果表明：铸态合金晶粒随着Ce含量的升高呈现先减小后递增的趋势；铸态合金的抗拉强度和导电性随着Ce的增加分别先升高后减低；当Ce的质量分数为0.06%时，铸态合金的抗拉强度最高、导电性最强.

| Abstract: | The structure and properties of copper alloy were improved by adding proper amount of rare earth elements.The as-cast Cu-3.0Si-2.0Ni alloy with different addition of Ce was designed,and a series of samples were fabricated after melting,casting and heat treatments.Effects of Ce on the structure and properties of as-cast Cu-3.0Si-2.0Ni alloy were investigated by means of tensile test and electric conductivity test at room temperature.The results show that the size of casting grain first decreased and then increased with the increasing addition of Ce.The strength and electric conductivity of cast alloy first increased and then decreased with the rise of Ce content.It is also found that the cast alloy obtained the best tensile strength and electric conductivity when the amount of Ce reached 0.06%. |
