Abstract: In order to study the deformation characteristics of a typical material powder metallurgy superalloy FGH96 used in aeroengine turbine disk, the Bodner-Partom (B-P) unified viscoplastic constitutive theory was used to construct its mechanical behavior of FGH96 at high temperature. Uniaxial tension and low cycle fatigue tests were carried out at 550 ℃, and the model parameters were identified and optimized by Levenberg-Marquardt algorithm. In order to improve the accuracy and reliability of the integration process, an integral step control strategy based on inelastic strain increment was introduced. The B-P model was introduced into ABAQUS finite element software through the user material subroutine UMAT for numerical simulation. The results showed that the FGH96 superalloy exhibits a certain rate dependence and cyclic softening characteristics at high temperature. The average relative error between the simulation curve and the test results is less than 10%, which shows that the B-P model can better simulate the deformation characteristics of FGH96 superalloy at high temperature, and the accuracy of the model and the UMAT subroutine is verified.
