Using ANSYS finite element software,the stress field of brazed joint which brazing filler metal is Ag-Cu-Ti was simulated between diamond and hard alloy by the means of the transient nonlinear analysis,it is predicted that the filler metal thickness has effect on residual stress and its distribution.Accordingly,the stress field of the region of diamond,filler metal and hard alloy is obtained and then the danger region in stress field is found by the analysis to various data groups.The brazing experiment is finished in vacuum furnace,the brazed joints with different filler metal thickness are obtained by different pressure on them.The shearing strength tests indicate it isn't that the more the thickness of filler metal is,the less stress in the filler metal is.The optimum thickness of filler layer exists.The experiment results agree with the calculated results.
