Abstract :

The Aluminium metal matrix has wide application in automobile, aerospace, sports and structure. Generally Al metal matrix composites are formed by powder metallurgy and direct casting technique. The powder metallurgy is a method in which composites are formed by mixing the elements with different chemical properties in metal matrix. This technique provides a good chemical homogeneity to final product, huge potential saving in case of mass production, high production rate and excellent wear resistant properties of component produced. Now in this research the three samples powder with following composition i.e (90% Al 7% SiC 3% B4C, 90% Al 5% SiC 5% B4C , 90% Al 3% SiC 7% B4C) with proper mixing and compacting by taking three compaction load of 3,4 and 5 ton, were taken for the evaluation of mechanical properties such as green and sintered densities, hardness, XRD etc. after analyzing the different properties it is seen that both green and sintered densities increases with increase in amount of Boron carbide but these are found to be maximum for 90% Al 5% SiC 5% B4C composition. XRD analysis is also done that showed equiaxed powder structure.
