晶界迁移属于物理学名词，是指在晶界两边物质的吉布斯自由能之差会使界面向曲率中心移动的现象。
条纹带是晶界迁移的结果。
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。
According to the results, the activation energy for migration of grain boundary Q was calculated. With the increase of the amount of re, the value of Q increases.
结果表明：平行于晶界方向的压应变可以促进晶界在相邻晶界交互作用下发生迁移；垂直于晶界方向的压应变则不能对晶界迁移产生明显的效果。
The results showed that a compressive strain parallel to the grain boundary enhanced the grain boundary migration, which is driven by the interaction between neighboring grain boundaries.
