The structural parameter for austenitic phasetransformation has a great effect on the characteristic of martensitic transformation.

发现奥体相变结构参数对体相变特性有很大影响。

The high wearing resistance of the samples after hydrocooling and air cooling was partially attributed to martensite transformation and work-hardening.

经水冷和空冷的试样具有高耐磨性的重要原因磨损过中诱发体相变,出现加工硬化现象。

It holds that main causes promoting crack on martensite stainless steel are gross martensite and crystal boundary carburet and secondary phase distributed along crystal boundary.

文章认为，粗大的体组织、晶界碳化物以及沿晶界分布的“第二相”组织促使体不锈钢产生裂纹的主要原因。

The crack initiates at stress concentration point in the root of weld, where has much more martenite, carbide and inclusion, and the serious hydrogen segregation.

裂纹均焊缝根部应力集中处萌生，该处体含量比较大，碳化物及夹杂物较多，氢的偏聚现象严重。
