A STUDY OF MECHANICAL PROPERTIES OF (AL-CU-MG) ALLOYS REINFORCED BY SILICON CARBIDE AND GRAPHITE PARTICULATES

Abstract

AbstractThis work deals with the preparing of composite materials based on aluminum alloy (2024)and reinforcement materials particles of silicon carbide and graphite powder . Silicon carbide are(3,5,7 wt%) , whereas the proportion of the graphite was certified at (3wt%) . All samplesadopted in this work are prepared by stir casting.The results have shown an increasing in mechanical properties such as ultimate tensile strength ,Yield strength , Hardness and compressive strength at the expense of ductility for compositematerial with increasing reinforcement materials content.
