摘要
利用铸造余热、采用中断正火的工艺研制出 ４５ ＳｉＭｎＣｒＭｏ新型耐磨材料，分析随中断正火温度的变化，材料的硬度、冲击韧性、耐磨性的变化规律，探讨性能变化的微观机理．从而可以得到既有良好的强韧性及耐磨性，且工艺简单、价格低廉的耐磨材料．
A new type of wear - resistant steel 45SiMnCrMo has been prepared by interrupt normalizing using waste heat of casting. The hardness, impact toughness and wear-resistance of the steel, which were treated at different interrupt-temperatures, have been tested. The micro-mechanism of the variation of property has been discussed. The obtained material has the advantages of ideal strength and toughness, good wear-resistance and low cost by simple process.
