Abstract

  The carbon equivalent of high strength cast iron melt with rare earth elements and manganese was changed variously and the mechanical properties of these specimen were examined. In addition, Cr, V, Mo and Cu elements was added to these melts and the mechanical properties of these specimens were also examined. As a result, the degree of normality (RG) was high in the high carbon contents with low silicon contents region, RG was 143. On the other hand, the relative hardness (RH) was low in the low carbon contents with high silicon contents region, RH was 0.8. The tensile strength was increased with increasing Cr, V and Mo addition except in the Cu element. High strength gray cast iron (upto 470 MPa in tensile strength) can be obtained by Mo addition combining with rare earth elements and manganese.
