Numerical Simulation of Microstructure Evolution of Superalloy Ring Forgings
The microstructure evolution during superalloy forging has great importance for process optimization and quality control. The forming of GH169 ring forging was studied, the forging process was initially confirmed and simulated based on the rigid-plastic finite element theory, and the grain size of the post-forming part was predicted. The accuracy of simulation was verified by comparing with physical and chemical analysis result. The finding of this paper shows reference values for microstructure forecast and development of reasonable forging process.
