When platemartensite is taken as original structure, the slow heating can make gram bainite inherit structure feature of original structure.
以板条马氏体为原始组织，慢速加热可使粒状贝氏体继承原组织特征。

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 observation by TEM showed that the formation of martensite in austempering process is preferentially completed through the coherent growth to prior martensiteplate.
