研究了不同合金元素Ga,Sn,In和Ni添加对Cd银基钎料及其钎焊接头的显微组织影响,同时对AgCuZn-X(Ga,Sn,In,Ni)钎料的对接和搭接实验做了对比实验分析.结果表明,添加Ga,Sn,In和Ni 4种元素的银钎料具有"特有的镓结构",具有较低的固相线和液相线,其钎缝力学性能优异,由SEM观察钎缝显微组织可知,低银含镓钎料具有与高银高镓钎料相近的织网状致密组织,添加适当的元素可以显著提高低银钎料的性能.

Ga, Sn, In and Ni were added into AgCuZn cadmium-flee brazing alloys. The influences of Ga, Sn, In and Ni on the microstructures and properties of AgCuZn brazing alloys were investigated. Mechanical properties of the butt and lap brazed joints were also tested. Results indicate that all AgCuZn-X(Ga, Sn, In, Ni) brazing alloys have low solidus and liquidus and acceptable mechanical properties. It is pointed out that the mechanical properties of the brazed joints are satisfactory due to the formation of fine network "characteristic gallium structure" when Ag and G-a contents are in a range of 30 wt%-56 wt% and 1 wt%-3 wt%, respectively, in the AgCuZn brazing alloy.
