The growth velocity for recrystallized grain is proportional to the driving force of recrystallization, which is determined by the grainboundaryenergy and dislocation density.
再结晶晶粒的生长速度与再结晶驱动力成正比，再结晶驱动力取决于晶界能和位错密度。

According to the results, the activation energy for migration of grainboundary Q was calculated. With the increase of the amount of re, the value of Q increases.
根据实验结果，对奥氏体晶界迁移激活能(Q)进行了计算，计算表明随稀土加入量增加，Q值亦增加。

Moreover, the rate-dependent deformation could also be explained from the point of grainboundaryenergy.
