However, because of fully granin refinement of martensite and good perfornance of temperresistance , the hardness of outer surface of worn side is equal to that of non-worn side.
而最表层由于获得完全细化的马氏体组织，拥有较好的回火稳定性，与未偏磨面表层硬度相当。

It shows that even granular bainite structure can be obtained in the condition of air quenching. The temperresistance is better and comprehensive mechanical properties of the steel are higher.
试验结果表明，该钢在空冷条件下可获得均匀的粒状贝氏体组织，具有良好的耐回火性和较高综合力学性能。

The influences of quench and temper treatment on the microstructure and wear resistance of white layer of the chilled cast iron were discussed.
