The point defects induced by electron irradiation make the lattice distortion of martensite phase and the increase of the ordering degree which bring about the stabilization of martensite.
相变温度的变化是由于电子辐照产生的点缺陷造成了马氏体相点阵畸变和有序度的变化，从而产生马氏体稳定化。
In order to prevent the yield-point elongation occurring the manganese equivalence in alloy must exceeds 1.61%, and the threshold value of Martensite volume fraction is 7%.
为了不发生屈服点延伸，合金中的锰当量必须超过1.61%，马氏体体积分数的门槛值为7%。
