Abstract
The stress-strain curves of 800H alloy were obtained by single gate heat compression simulations experimental,and the dynamic recrystallization behavior and mutagenic precipitates under different deformation conditions were studied.The results show that deformation energy storage of 800H alloy in high strain rate increase with the increase of dislocation density in the high temperature deformation process, and the critical temperature of dynamic recrystallization decreases. The critical temperature of 800H alloy, at which the change of the amount of precipitated phase occur, is 950 ℃ under the experimental conditions.
