Abstract Abstract��It had been studied that the effect of deformation temperature and strain-rate and strain and original grain size on stress-strain law by with thermal simulation experiment. It was analyzed that the effect of factors on crystal grain size of dynamic recrystalization (DRC). It was established that the kinematics model of super-alloy GH4169, which was relationship between the grain size of dynamic recrystallization(DRC) and function Z and technology parameters. It was established that the dynamics model of super-alloy GH4169, which was relationship between the quantity of dynamic recrystalization and function Z and technology parameters. The results presented that the grain size of dynamic recrystalization increased with increasing of temperature, and increased with the reducing of strain-rate. And it having no relationship with original grain size. The quantity of dynamic recrystalization reduced with increasing of original grain size.
