Further more, tension stress near handhole was in the range of designed value.

而手孔部位的局部主拉应力较小，均在控制应力范围之内。

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，均使组织中残余奥氏体数量减少，形貌由无应力时的块状变为条状或薄膜状。
