采用铸造金热中断正火的工艺，研制出ZG45SiMnCrMo新型耐磨材料，分析了中断正火温度、保温时间等不同材料的硬度、冲击韧性、耐磨性的变化规律，探讨了性能变化的微观机理，找出了此耐磨材料中取得最佳强韧性配合时的复合组织中下贝氏体的大致百分含量，从而得到既有良好的强韧性及耐磨性．价格又低廉的耐磨材料．
ZG45SiMnCrMo new wear-resistant material was developed by the process of casting gold-hot-cut normalizing, and the variation regularity of hardness, impact toughness and wear resistance of different materials such as the interruption of normalizing temperature and holding time were analyzed, and the microscopic mechanism of performance change was discussed , Find out the approximate percentage of the lower bainite in the composite tissue when the best toughness is obtained in the wear resistant material so as to obtain both good toughness and wear resistance. Low price and wear-resistant materials.
