| Abstract: | An investigation was concerned with the effect of alloying elements Nb,V,Cu and rare earth (RE) modifier on the structure and properties of high Cr Mn white cast iron (15 %Cr,4 %Mn) by means of orthogonal matrix.The results show that alloying elements and rare earth can refine grain,change carbide morphology and distribution,and increase mechanical properties and wear resistant properties.The optimum chemical composition and heat treatment process of multi element low alloys high Cr Mn white cast iron have been determined. |
