During two cooling methods, whether tension stress or compression stress, the retained austenite in steel reduced with stress increasing, had become from massive to streak or filminess.

在两种冷却方式下，不论拉还是的作用，均使组织中残余奥氏数量减少，形貌由无时的为条或薄膜。

In the former case,the solute segregation in dendritical austenite more severe,and there were lumps of distortion inclusion.

前者枝晶奥氏内溶质偏析大，有畸夹杂团。
