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，有畸变夹杂团块。

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的作用，均使组织中残余奥体数量，貌由无应力时的块状变为条状或薄膜状。
