silicon carbide(sic) powder can react with iron(Fe) or close to normal sintering Fe-base powders at temperatures 5wt.% temperatures of such Fe or Fe-base powders. Sintering of Fe like Sic powder mixture at 1200"C resulted in the microstructure of nodular graphite-like particles surrounded with ferrite and then with structure or ductile cast microstructure. Similar microstructure was also reported in other systems. it is expected that the elemental powder additions to the sintered materials with microstructure ductile cast iron-like microstructure. Copper(Cu) and nickel(Ni) are the common additive powders mixed with Fe powder to produce sintered Fe-base materials. The additions of Cu and Ni in Fe- 0.85Mo 0.6 wt.% graphite powder mixtures resulted in mechanical property modifications[5]. However, the microstructures of the Fe-0 SiC steels modified by additions of cu, or Ni or graphite and sintered at temperatures higher than normal industrial sintering temperatures of was powder have not been reported. In this work, microstructural focused to identify effects and graphite additions on microstnuctural development and its consequence on tensile properties
