通过对奥氏体再结晶行为的研究得到35CrMo钢发生动态再结晶的形变条件为：形变温度T>1000℃, 应变速率1/s。描述动态再结晶动力学方程f=1-exp(-b(Z)tn(Z))中的系数b和n与变形参数Z有关。计算值与实测值较为吻合。通过非线性回归得到35CrMo钢的动态再结晶晶粒尺寸的关系式为：DDRX=2.25104Z-0.22。通过双道次压缩和单道次压缩保温实验，得出35CrMo钢静态再结晶激活能和动力学方程。
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.
