Abstract：

Axial closed dies rolling(ACDR)process of GH4169 alloy forging for compressor disk of aircraft engine was simulated using rigid-plastic finite element method. And the material flow pattern, thermo mechanical parameters within forging, billet filling of dies cavity and deformation load during ACDR were clarified. Comparing with forging produced by hydraulic press, the simulation results show that the deformation is sufficient, the temperature homogeneity is more satisfied and the distribution of flow lines is more reasonable within the forging produced by ACDR. Under the same conditions, the maximal deformation load of ACDR process is only one tenth of the maximal deformation load for hydraulic press forging.
