摘　　要：选用合理的电子束钎焊工艺参数,获得了良好的钎焊接头。用扫描电镜和能谱分析仪对钎焊接头的显微组织进行了分析。结果表明,钎料区主要是固溶体组织;母材区除了奥氏体组织外,存在铜元素的扩散。The good joint was obtained by using proper parameters. The microstructure of the brazed joint was analyzed by means of a scanning electron microscope and an energy spectrum analyzer. The results show that the microstructure of brazing filler metal is mostly solid solution phase.Other than austenite,copper element dissolution is found in material.
