austenite

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

前者枝晶奥体内溶质偏析大，有杂团块。

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，不论拉应力还是压应力作用，均使组织中残余奥体量减少，形貌由无应力时块状为条状或薄膜状。
