摘要(Abstract)：

通过显微组织观察、力学性能测试研究了不同冷却方式对热处理后ZG35Cr2NiMoVTi铸钢的组织及力学性能的影响,并与高锰钢(Mn13)进行了比较。结果表明,ZG35Cr2NiMoVTi钢炉冷组织为少量铁素体+珠光体,空冷、风冷组织为少量铁素体+珠光体+贝氏体,油淬、水淬组织为板条马氏体+少量残留奥氏体;其硬度随冷速提高而增加,水淬后硬度达最高值52 HRC;冲击韧性随冷速提高先增加后下降,风冷时最佳,油淬、水淬时较低。在冲击功为4.5 J的冲击磨料磨损条件下,其耐磨性随着硬韧性的增加而提高,炉冷最差,空冷、风冷后逐渐提高,油淬、水淬时较好;油淬、水淬时的耐磨性已优于高锰钢(Mn13)。
