| Abstract: | In this paper, the effects of multi-component micro-alloying and heat treatment on the microstructure, mechanical properties and abrasion resistance of medium-Mn white iron containing RE alloy were investigated. The results obtained show that the structure of medium-Mn white iron is fined by multi-component alloy, multi-component alloy tend to increase the hardness of mentioned white iron, but the mobile fracture toughness and the wear resistance were raised by 46.7% and 83.1% respectively. Using new technology of heat treatment, the wear resistance of medium-Mn white iron was raised further. |
