| 摘 要： | 利用双道次压缩的方法，在Gleeble-1500热模拟实验机上研究了C-Si-Mn系双相钢在变形间隔时间内奥氏体的软化行为。采用后插法计算了在不同真应变条件下的静态再结晶率，通过双道次压缩测试静态软化动力学的实验表明，实验钢变形后很容易发生静态软化。在真应变为0．3时，静态再结晶激活能是99．971kJ／mol。 |
| 关 键 词： | 双相钢 静态软化 静态再结晶 |

| Abstract: | The static softening behavior of C-Si-Mn dual-phase steel as-hot-rolled using double-stage hot compression was studied on Gleeble 1500 tester.The static recrystallization fraction under different strain was estimated by means of back-extrapolation.The tests of the static recrystallization softening dynamic by double-stage hot compression indicate that the static softening of samples after deformation occurs easily.The activation energy(Qrec) of the static recrystallization is 99.971 kJ/mol when the strain is 0.3. |
| Keywords: | dual-phase steel static softening static recrystallization |
