| Abstract: | influences of types of modificators and their added volume fractions on the structure and properties of The medium-chromium cast iron under the same experiment condition were investigated in this article. The results showed that the modification effect of
compound modificatator was best, by which, the high hardness, the high toughness and excellent wearing resistance could be achieved in medium-chromium cast iron.The modification effects of low-carbon ferrochromium and rare-earth ferrosilicon took second place. |

| Keywords: | medium-chromium cast iron modification modificator structure property wear resistance |
