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

现奥氏体相变结构参数对马氏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性的重要原因是其过中马氏体相变,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，粗大的马氏体组织、晶界碳化物以及沿晶界分布的“第二相”组织是促使马氏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，该处马氏体含量比较大，碳化物及夹杂物较多，氢的偏聚现象严重。
