| 摘 要： | 为研究贝氏体非调质紧固件用钢的动态再结晶行为，在Gleeble-3500热模拟试验机上进行了单道次压缩试验，并分析了压缩变形应力-应变曲线。研究表明，奥氏体热变形激活能较一般C-Mn钢要高，为427.065kJ/mol；再结晶开始时间与温度曲线在1000℃左右出现明显的转折点，温度低于1000℃时，动态再结晶发生困难。 |
| 关 键 词： | 贝氏体非调质钢 动态再结晶 热变形激活能 RTT曲线 |

| Abstract: | In order to characterize the dynamic recrystallization behavior of a bainitic non-quenched and tempered steel,single compression tests were performed on a Gleeble-3500 simulator.The stress-strain curves obtained were analyzed.The results show that the activation energy of deformation is 427.065 kJ/mol,which is higher than the plain C-Mn steel.There is a turning point on the recrystallization beginning time and temperature(RTT) curve at about 1 000 ℃.The dynamic recrystallization is more difficult to occur when the temperature is below 1 000 ℃. |
| Keywords: | bainitic non-quenched and tempered steel dynamic recrystallization hot deformation activation energy RTT curve |
