摘要
对锻造掺杂La2O3合金钼棒在1 360～1 500℃之间的静态再结晶组织演变和动力学机制进行了研究。结果表明,再结晶分数与退火时间之间的关系可以用J-M方程来描述。根据动力学分析,可以计算出掺杂La2O3合金钼棒的再结晶激活能Qr值为166.949～173.545 kJ.mol-1。
The microstructure evolution and static recrystallization kinetics at different annealing temperature ranged from 1 360 - 1 500 ℃ of forgingLa2O3-doped Mo alloy were researched. The experiment results demonstrated that the relationship between the annealing time and the fraction of recrystallization grains could be described by the J-M equation. Based on the kinetics analysis, the activation energy of recrystallization was calculated to be about 166. 949 -173. 545 kJ mol-1
