| Abstract |
Uniaxial tensile tests of GH3128 on a Gleeble-3800 thermal-mechanical physical simulation machine were carried out under the temperature and stress of 850ºC, 900ºC and 950ºC, 50 MPa, 65 MPa, 80 MPa and 100 MPa, respectively. According to the test data, two creep constitutive equations based on strain-time creep model and Norton power law creep model were obtained. By comparing the calculated values of the two constitutive equations with the test values, it could be found that the calculated values based on the Norton power law creep formula are closer to the experimental values than those based on the strain-time creep formula. Therefore, the constitutive equation based on Norton power law creep model could be used to estimate the creep deformation of the material at high temperature and high stress during operation. |
