Analyzing the mechanical properties of aluminium (SiC, B4C) hybrid Composite

Abstract

Abstract Aluminium MMCs is play the major role in the industrial sectors. The aluminium MMCs are providing superior properties which cannot achieved by existing monolithic material. Now a days the more research is involves to the development of aluminium MMCs. Here we are choosing Al 7475 is a base metal and reinforced with SiC, B4C by stir casting method. The different combinations of composition in volume fraction were chosen like 85%Al 7.5%SiC 7.5%B4C, 85%Al 5%SiC 10%B4C, 85%Al 10%SiC 5%B4C. The stir casted composite is machined carefully to prepare specimens of micro hardness. The mechanical properties are including the micro hardness. The stir casted composite is machined carefully to prepare specimens of micro hardness (Vickers test), tensile test, impact test (Charpy test) and micro structure as per the ASTM standards. The composition of 85%Al 7.5%SiC 7.5%B4C, was given more hardness, tensile strength and impact strength has 126.33VHN, 196.79N/mm2 and 2 Joule. As increased the percentage of SiC is increase the mechanical properties of the Al MMC.
