When unstable thermal conditions are satisfied with the constituent fluctuations of "correct direction" and "degree", phase transformation driving force is raised and nucleation is promoted.

当成分起伏的“方向性”和“程度”满足形核的热力学条件时，相变驱动力增加，可以促使钢液形核。

The IF behaviour in the processes of MP and I/C phase transformations are nearly the same and is associated with the motion of phase interface under the action of phase transformation driving force.

结果表明，变温马氏体相变及I/C相变过程中内耗均为粘弹性型内耗，是相界面在克服粘滞性阻力而运动时引起的。
