Abstract
The Aluminum matrix composites (AMCs) are emerging as advance engineering materials due to their strength, ductility and toughness. The aluminum matrix can be strengthened by reinforcing with hard ceramic particles like Sic, Al2O3,B4C etc. In the present study, an effort is made to enhance the mechanical properties like tensile strength and hardness of AMCs by reinforcing 6061Al matrix with B4C particles. By stir casting route, aluminum matrix was reinforced with boron carbide particulates of 37, 44, 63, 105, 250µ sizes respectively. The microstructure and mechanical properties of the fabricated AMCs was analyzed. Based on the results obtained from tensile strength test of the metal matrix composites of different particle sizes, 105µ size B4C was chosen and varied the wt% of B4C with 6,8,10 and 12wt%. The optical microstructure images reveal the homogeneous dispersion of B4C particles in the matrix. The reinforcement dispersion has also been identified with X-ray diffraction (XRD). The tensile strength and hardness was found to increase with the increase in the particle size and also with the increase in wt% of the reinforcement
