摘要：
The effect of thermomechanical processing schedules on the formation of submicrocrystalline and nanocrystalline structure in EP962 nickel high alloy was studied. A microstructure with 0.05-0.08 mu m grains can be obtained during recrystallization on hot deformation. An alloy with 0.25 mu m grains exhibits superplasticity at 800 degrees C (0.7 T-m.p.) which is 200-275 degrees C lower compared to the common fine-grain state.
