| 摘 要： | 研究了稀土元素镧对Ag-Cu-Ti钎料合金微观组织、物理性能和显微硬度的影响。实验结果表明，添加一定量的稀土元素镧对Ag—Cu—Ti钎料合金的熔化温度无明显影响，但可显著提高钎料合金的润湿性能和显微硬度。分析结果表明，稀土元素镧可以细化钎料合金的微观组织，使金属间化合物分布更加均匀。这也是实验条件下Ag—Cu—Ti钎料合金显微硬度提高的主要原因。钎料Ag—Cu—Ti合金中稀土镧加入的质量分数不应超过0．5％。

| Abstract: | The effects of rare earth Lanthanum on the mierostructure,the physical property and the microhard-ness of Ag-Cu-Ti solder alloy are studied.Experimental results indicate that the addition of Lanthanum can evi-dently improve the wettability and the microhardness of Ag-Cu-Ti solder alloy.Analysis results show that the in-crease in microhardness is related to the refining and uniform distribution of the intermetallic compounds.Proper content of Lanthanum added in Ag-Cu-Ti alloy solder can be controlled below 0.5% in mass percent. |
