研究了用Ag-Cu-Zn-Sn钎料对黄铜和钢进行感应钎焊的工艺。采用光学显微镜、扫描电镜和电子探针显微分析等方法分析了银含量对合金显微组织和性能的影响。采用Ag-Cu-Zn-Sn填充金属实现了无缺陷连接。接头组织主要由ag基固溶体和cu基固溶体组成。Ag含量的增加和冷却速度的增加都导致了针状共晶组织的增加。拉伸强度随Ag含量的增加而降低。Ag25CuZnSn填充金属的室温拉伸强度达到445 MPa。所有Ag-Cu-Zn-Sn钎料断口均呈现延展性特征。
The induction brazing of brass to steel using Ag-Cu-Zn-Sn filler metal was investigated in this study. The influence of Ag content on the microstructure and properties were analyzed by means of optical microscopy, scanning electron microscopy and electron probe microanalysis. Defect free joint was achieved using Ag-Cu-Zn-Sn filler metal. The microstructure of the joint was mainly composed of Ag-based solid solution and Cu-based solid solution. The increase of Ag content and the cooling rate both led to the increase of the needle like eutectic structure. The tensile strength decreased with the increase of Ag content. The tensile strength at room temperature using Ag25CuZnSn filler metal reached 445 MPa. All fractures using Ag-Cu-Zn-Sn filler metal presented ductile characteristic.
