| Abstract: | The carbid type of the ware-resistant Mn-B white cast iron and the influence of manganese and austenitizing temperature on the amount of the residual austenite are studied by experiments. The experimental results show that raising the amount of manganese and the austenitizing temperature would increase the amount of the residual austenite and then cause the reduction of the hardness and the ascension of impact toughness of the wear-resistant Mn-B white cast iron. |
