| Abstract: | The effect of RE modification on the microstructure and impact toughness of wear resistant white cast iron are investigated.The results show that the eutectic carbide network will be breaked up and impact toughness increased by RE modification.RE modification followed by heat treating will obtain more noticeable effect for the wear resistant cast iron. |
