In this study, the microstructure and mechanical performance of Fe-based composites reinforced by FeTi+B4C at various ratios were determined. The study was based on the production of Fe based nano carbide and boride (B4C, Fe2B, Fe7C3, TiB2) reinforced composites. Mechanical alloying technique was chosen to reduce the reinforcement material to nano size and distribute it homogeneously. Sintering temperature was used as 1,100 °C and sintering time as 2 h. The reionforcement “FeTi+B4C” ratio was raised up to 15 wt.%. The microstructure and phases of the composite samples were descrived by scanning electron microscopy, energy dispersive spectroscopy, X-RD analysis and hardness. The concentration of voids and the stiffness changes of the samples were determined. The size of TiC and TiB2 particles reduced significantly with the rise in B4C ratio. Since the hardness of TiB2 was less than that of the B4C matrix, the hardness reduced with increasing TiB2 ratio.
