| 摘 要： | 通过在Gleeble-3500热模拟试验机上进行的两道次热压缩变形试验,对含铌微合金管线钢的静态软化行为进行了研究。采用应力补偿法计算了不同变形温度下的静态再结晶百分数。变形温度和弛豫时间对X120钢的静态再结晶影响很大。根据试验数据和静态再结晶动力学方程,计算出X120管线钢静态再结晶激活能为401.56kJ.mol-1。绘制了试验钢的析出动力学(PTT)曲线。 |

| Abstract: | Static recrystallization behavior of microlloyed pipeline steel with Nb was investigated by two-pass uniaxial hot compression tests performed on Gleeble-3500 thermo-mechanical simulator.The static recrystallization fraction under different deformed temperatures was estimated by means of compensating.The results show that the effect of deformation temperature and inter-pass time on static recrystallization behavior is significant.The activation energy of static recrystallization of the X120 pipeline steel is 401.56 kJ/mol.The precipitation-time-temperature curve of the X120 pipeline steel is also obtained. |
| Keywords: | X120 pipeline steel static recrystallization precipitation-time-temperature curve |
