摘　　要：本文针对采用坩锅炉钎焊工艺获得的1Cr18Ni9Ti不锈钢与6A02铝合金异种金属钎焊接头进行了接头形貌及微观组织分析。通过金相检查的方法阐述了接头宏观形貌及界面组织特点;使用扫描电镜进行了高倍组织观察及能谱测量,从而进一步分析了钢/铝异种金属界面层结构,并对接头典型缺陷进行了描述和分析。The morphology and the microstruc-ture of 1Cr18Ni9Ti stainless steel and 6A02 aluminum alloy dissimilar metal joints obtained by the crucible fur-nace brazing process are analysis in this paper. The macro morphology and the microstructure characteristics of the joints were expounded through metallographic examina-tion;Scanning electron microscopy is used to observe the microstructure and measure the energy spectrum, thus the steel/aluminum dissimilar metal interface layer structure is further analyzed, and the typical defect of the joint is de-scribed and analyzed.
