ABSTRACT : |
Aluminum-based composites reinforced with hard ceramic particles are a unique advancement in engineering materials that have been developed to use in high strength, high wear resistant. In this paper aluminum metal matrix composite was fabricated by reinforcing various weight percentages of boron carbide particles using stir casting technique. By the addition of feTiFe into the metal, the wettability of boron carbide particle has been improved. The microstructure and mechanical properties of the composite were investigated. The microstructures were analyzed by optical microscope (OM) and the SEM structure shows the homogenous distribution of boron carbide in aluminum matrix. By increasing the weight percentage of boron carbide in the aluminum matrix the hardness and tensile have been considerably improved.
