Abstract The recrystallization behavior of the steel 35CrMo during hot deformation was investigated using physical simulation experiments, and the condition of dynamic recrystallizaiton (DRX) was obtained to be: T>1000℃, A modified DRX kinetic equation is submitted , from which the DRX fraction calculated is good agreement with the experiments. An equation describing dynamic recrystallization grain size can be written . Through the 2-stroke compression and 1-stroke compression followed by holding temperature experiment, the activation energy and kinetics equation of static recrystallization (SRX) of the steel 35CrMo are also obtained.

Key words: steel 35CrMo kinetic equation grain size
