Effect of Steel Slag on the Impact Strength of Aluminium Metal Matrix Composite

Abstract

ABSTRACTAluminium alloys are used in advanced applications because their combination of high strength, low density, and durability. However, the properties of this material can be improved by using aluminium matrix composite materials. By reinforcing hard ceramic particles like SiC, Al2O3and B4C, TiO2 etc the strength of the composite can be enhanced. In this paper an effort is made to enhance the property of AMCs by reinforcing steel slag particle with A356 matrix. By varying the weight percentage of the steel slag the composite material was prepared through stir casting method. The mechanical property like hardness and impact strength of A356 was investigated and compared with that of composite material. The result reveals that by increasing the reinforcement percentage of steel slag the impact strength decreases with the increase in hardness of the composite material. The density is also compared with that of A356 composite.
