Abstract：

The hot die forging technique of turbine disc was optimized based on orthogonal experimental design method during the finite element simulation using Deform-3D software. The effects of process parameters on the microstructure were also systematically analyzed. The results show that high quality product of GH4169 turbine disc can be expected through the hot die forging. The optimal parameters are the deformation temperature of 1010 ℃, the die temperature of 960 ℃, the deformation rate of 1 mm·s-1, the frictional coefficient of 0.02. At the same time, a turbine disc was manufactured in accordance with the optimal process, and the anatomical analysis was carried out on the actual turbine disc. The results confirm that the simulation results and anatomical analysis results are in good agreement, so the research method can provide some feasible research method and theoretical basis for the optimization of the practical process parameters.
