Abstract:The thermophysical simulation of a new wrought superalloy GH4066 was carried out by Gleeble-3800. The high temperature flow stress characteristics of this material under different deformation conditions such as the temperature of 800, 900, 1000, 1100℃ and 1150℃, and the strain rate of 0.0003, 0.001, 0.01, 0.1, 1, 10 s-1 were obtained. Based on the experimental data and the phenomenological model, the constitutive model of the material was established. The dynamic recrystallization and grain growth model of the material were also obtained. All the models are embedded into the finite element software to simulate the forging process of the turbine disc made by this material. As the numerical simulation results, the reasonable range of the thermoforming parameters for the turbine disk can be concluded.Finally, the material models are verified and an integrated method of experiment and calculation for the material models construction are established. That is a quite useful method for the parameters determination for the turbine disk forging process of this new material.
