Summary:The prediction models of microstructure evolution and calculation procedure for GH4169 alloy were established with a comprehensive consideration on the interaction of deformation parameters, increasing temperature and the cooling rate during hot deformation. Besides, a double cone sample was chosen as experimental shape, whose size was about phi 200mmx160mm for better reflect real situation that the distribution of strain, temperature, cooling rate were different in different sample locations. Then, the simulation and verification for microstructure evolution were carried out at the deformation temperature of 980, 1020, 1060 degree C and 1120 degree C. The results showed that the double cone samples were in accordance with practice deformation situation. The prediction model of microstructure evolution was reasonable for using and it can achieve the real microstructure results for deformation.
