Stabilizing treatment fixture for titanium alloy designed by conventional methods is thick and heavy,and the verification cycle is long.By studying the high temperature tensile and creep behavior of the TA15 titanium alloy,a finite element model of the high temperature rupture lifetime of titanium alloy was established to simulate the deformation of the fixture under high temperature loading conditions and optimize the fixture structure.The results indicate that based on the creep test results and the Allometric1 function in the data analysis software,the creep constitutive equation of the TA15 titanium alloy is(ε)=7.411 × 10-8σ2 759.The ABAQUS quasi-static analysis module and the creep constitutive equation of the TA15 titanium alloy can be used for the verification of stabilizing treatment fixture,providing a basis for its optimization design.
