摘　　要：开发了Au-32Ag-6Ge新型金基中温钎料。采用DSC、SEM对钎料的熔化特性及显微组织进行分析,并初步研究了钎料钎焊铜母材的接头强度,并对接头的界面组织进行了分析。结果表明,钎料合金的熔化温度区间为500.9~531.1℃;钎料合金主要由AuAg固溶体和骨架状富Ge相组成;钎焊后的界面处形成了良好的冶金结合,钎料合金与Cu基体形成金属间化合物;580℃钎焊铜时,接头的平均剪切强度为230.9Mpa。A new-type Au-Ag-Ge medium-temperature brazing alloy was prepared.The melting characteristic and microstructure of the brazing alloy was analyzed by using DSC and scnning electruon microscope,the mechanical tests and the interface microstructures observations of the brazing joints of copper with copper have been conducted.The results show that,the melting temperature of the brazing alloy is in the range of 500.9~531.1℃,main microstructures of the brazer metal were AuAg solid solution and skeletion Ge-rich phase.Theaverage shear strengthen of copper joints reached 230.9Mpa when 580℃under the braze welding.
