摘要:

近年來，釬焊技術的廣泛應用帶動了釬料的快速發(fā)展。Al-Si系釬料具有良好的流動性和潤濕性，但其熔化溫度高、強度偏低、焊接裂紋敏感性高且具有液相腐蝕傾向，這些缺點制約了Al-Si釬料的應用范圍的擴展。為了細化Al-Si系列釬料的合金組織，可通過添加稀土元素對其進行變質處理，使焊縫在釬焊后獲得優(yōu)良的性能�；�于此，綜述了Ce，Y，Er和Yb等多種稀土元素對鋁合金釬料顯微組織及焊后力學性能的影響，并對其細化晶粒機理進行分析。結合國內(nèi)外對鋁合金釬料的研究進展，對目前鋁合金釬料在開發(fā)過程中組織細化的問題以及未來釬料的發(fā)展趨勢進行了展望。

Abstract:

In recent years, the wide application of brazing technology has led to the rapid development of brazing solders. Al-Si brazing solders has some advantages such as good fluidity and wettability, at the same time, it also has some disadvantages, such as high melting temperature, low strength, high weld crack sensitivity and liquid phase corrosion tendency, which restrict expansion of the application range of Al-Si brazing solders. In order to refine the alloy structure of Al-Si brazing solders, it can be modified by adding rare earth elements, so that the weld obtained excellent performance after brazing. Based on this, this paper reviews the effects of Ce, Y, Er, Yb and other rare earth elements on the microstructure and mechanical properties of aluminum alloy solders after brazing, and analyzes the mechanism of grain refinement. Based on the research progress of aluminum alloy solder at home and abroad, the problem of microstructure refinement in the development process of aluminum alloy solder is pointed out, and the future development of solder is prospected.
