austenite

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

前者枝晶奥氏体内质偏析大，有畸变夹杂团块。

the sawtooth austenite boundaries become preferential nucleation sites of ferrite, and the sawtoothed ferrite boundaries contribute to the formation of ferrite recrystallization nucleus.

锯齿状的奥氏体晶界优先成为铁素体的形核位置;

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，不论拉力还是压力的作用，均使组织中残余奥氏体数量减少，形貌力时的块状变为条状或薄膜状。

The second carbide is dispersed in the matrix which has good plastoelastic retained austenite, also slows up the material loss when the sands erode the surface.

基体中弥散分布着二次碳化物及具有良好弹塑性的残余奥氏体，也减缓了砂粒冲刷表面时的材料流失；
