austenite

1.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。

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

锯齿状奥氏体晶界优先成为铁素体核位置;

3.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，不力还是压力作用，均使组织中残余奥氏体数量减少，貌由无力时块状变为条状或薄膜状。

4.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残余奥氏体，也减缓了砂粒冲刷表面时材料流失；
