| Abstract: | 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. |
