    摘要:

    利用光學(xué)顯微鏡、掃描電子顯微鏡（SEM）和能譜分析儀(EDX)及Instron電液伺服疲勞拉伸試驗機，對SnAgCu系無鉛釬料合金的力學(xué)性能和釬焊性能進行了研究。結(jié)果表明，適量的稀土元素Ce的添加顯著地延長了Sn3Ag2.8Cu釬焊接頭在室溫下的蠕變斷裂壽命，Sn3Ag2.8Cu-0.1Ce釬焊接頭的蠕變斷裂壽命超過Sn3Ag2.8Cu釬料的9倍；同時，使Sn3Ag2.8Cu合金的延伸性能也得到了顯著改善，伸長率達到15.7%；Sn3Ag2.8Cu-0.1Ce與銅基板的擴散層厚度比Sn37Pb厚，但是比S

    Abstract:

    The mechanical property and solder ability of SnAgCu system lead-free solder alloys were studied by means of optical microscopy, scanning electron microscopy(SEM), energy dispersive X-ray(EDX) and Instron electrohydraulic servo fatigue tensile tester. The results indicate that proper quantities of Ce can remarkably prolong the creep-rupture life of the Sn3Ag2.8Cu brazing joint at room temperature, and the creep-rupture life of the Sn3Ag2.8Cu-0.1Ce brazing joint is 9 times or more than that of the Sn3Ag2.8Cu; meanwhile, the elongation of the Sn3.0Ag2.8Cu-0.1Ce solder alloy is also obviously improved even up to 15.7%; the intermetallic layers of the Sn3Ag2.8Cu-0.1Ce with copper plate are thicker than that of Sn37Pb, but thinner than that of Sn3Ag2.8Cu.
