摘要：
Four kinds of silver base brazing materials were adopted for fabricating brazing joints of titanium alloy and stainless steel. The mechanical properties of brazing metal at contact face was measured and the fracture morphology and structure of interface were studied by mechanical test, metallographic examination, SEM analysis and electron probing analysis. The result shows that the strength of brazing metal at stainless steel/Ag95CuLi/Titanium alloy was 220 MPa, 242 MPa at stainless steeVAg88A110MnSi/ritanium alloy, 123 MPa at stainless steel/Ag85Al8Sn/Titanium alloy, and 280 MPa at stainless steel/Ag85A18SnNi/Titanium alloy. The fragile phase was easy formed in the diffusion part of stainless steel/Ag95CuLi, and cracking in the stainless steel/Ag88A110MnSi. And there is a wonderful coalescence on metallurgy between the brazing materials and titanium alloy or stainless steel.
