| Abstract: | According to the experience of hightemperature, shorttime drawing test and multiple simulated creep test for 316L stainless steel diffusionbonding joints, the creep test is carried out on the hightemperature creep strength tester, and the creep deformation and fracture time are recorded. The individual feature quantities of the twoparameter Weibull distribution are determined based on the parameter evaluation method of Weibull distribution. The average fracture time of 316L stainless steel diffusionbonding joints at high temperature is determined by Weibull distribution model and reliability evaluation method. |
