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

发现奥氏体结构参数对马氏体性有很大影响。

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是其在磨损过中诱发了马氏体,出现加工硬现象。

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、晶界碳及沿晶界分布的“第二”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.

裂纹均在焊缝根部应力集中处萌生，该处马氏体含量比较大，碳及夹杂较多，氢的偏聚现象严重。
