| Abstract: | Effect of hot deformation amount on structure and impact toughness of the wear resistant complex alloy cast iron has been investigated. The results show that the hot deformation will change shape and distribution of eutectic carbides in the wear resistant alloy cast iron and accelerate precipitation of the granular carbides so as to improve on impact toughness of the cast iron, and that hot deformation amount of 40% will enable the cast iron to obtain the best impact toughness. |

| Keywords: | wear resistant complex alloy cast iron hot deformation structure impact toughness |
