Description:
It studied the organization form of GH4169 alloy which had been obtained with different temperatures, strain-rates, deformations and original grain sizes by the high temperature hot compression tests. Influence laws of process parameters to microstructure evolution during hot deformation were gotten. The results showed that the grain group was hybrid when the temperature below 940°C, while complete recrystallization happened above 1020°C. Uniform equiaxed grains had been gotten with the strain-rate below 0.01s −1 , and temperatures between 980-1020°C.
