| 摘 要： | 向Sn-0.70Cu-0.05Ni无铅钎料中添加微量混合稀土元素RE(主要是La和Ce),研究了RE添加量对该钎料合金显微组织及性能的影响.结果表明,添加微量的RE能显著细化该钎料合金组织,抑制金属间化合物的生长,改善合金的组织分布,提高钎料的润湿性及力学性能.当w(RE)为0.10%时,钎料的润湿力,拉伸强度分别为3...

| Abstract: | In order to explore the influence of RE (rare earths) on the Sn-0.70Cu-0.05Ni solder alloy,various micro amounts of RE,which are mainly La and Ce,were added into this alloy and their properties were investigated.The results show that adding micro amount of RE could refine the microstructure of the solder alloy and inhibit the growth of intermetallic compounds.Meanwhile,more uniform microstructure,improvements of the wettability and mechanical properties were obtained with RE addition.When the mass fraction ... |
