| 摘 要： | 采用Gleeble 1500热模拟实验机对F40MnV非调质钢在温度为1 223~1 473 K，应变速率为01~10 s-1的热变形行为进行研究。通过奥氏体再结晶动力学回归计算得到了F40MnV钢的变形激活能，峰值应力和峰值应变与Zener Hollomon参数的关系表达式。同时，得到了F40MnV钢的动态再结晶动力学方程和动态再结晶晶粒尺寸的数学模型。

| Abstract: | Hot compression test of F40MnV without quenching-and-tempering steel was conducted on Gleeble 1500 at the temperature 1 223-1 473 K and strain rate of 0. 1- 10 s^-1 to research its hot deformation behavior. The deformation energy was caculated. The dependence of the peak stress and peak strain on Zener-Hollomon parameter was studied. The mathmatical models of volume fraciton and grain size after dynamical recrystallization were also obtained as follows. |

| Keywords: | F40MnV steel quenched and tempered steel flow st ress dynamical recrystallization |
