The observation by TEM showed that the formation of martensite in austempering process is preferentially completed through the coherent growth to prior martensiteplate.
通过TEM观察表明，等温马氏体形成时，将优先以原马氏体片共格长大的方式进行。

The results show that martensite at transition area and the thermal stress in the joint of different material will cause crack in clad steel plate during welding.
结果表明，过渡区马氏体组织的生成，异种钢接头的热应力是产生焊接裂纹的主要原因。

The presence of a certain amount of retained austenite improves the resistance to contact fatigue failure. The lath martensite has better resistance than the plate twin martensite.
