摘要
Abstract
Carries out studies aiming at vacuum brazing technology and joint reliability problems of titanium alloy and YG8 hard alloy dissimilar materials,the microstructures,Vickers hardness and joint shear strength of Ag94AlMn brazing joint are tested and analyzed by wetting experiment,metallographic microscope,microhardness tester,tensile testing machine,scanning electron microscope experiment and test method.The test results show that the silver based solder are well bonded with titanium alloy and cemented carbide,the surface of weld is uniform and no micro cracks.The brazing structure is Ag-based solid solution,the cemented carbide base material Co,the W element and the Titanium alloy base material Ti,V elements diffuse little in the brazing seam,almost no base material dissolution;TC4 and YG8 vacuum brazing of dissimilar metal vacuum brazing,choose silver based solder and brazing temperature of 920 ℃,holding time of 10 min,the maximum shear strength of the joint.关键词
