Effect of Fabrication Methods on Mechanical Properties and Machining Parameters of Aluminium Matrix Composites-A Review

Abstract

Aluminium matrix composites (AMCs) are potential material for numerous applications due to their excellent mechanical and physical properties. The stiffness, specific strength, wear, creep and fatigue properties can be enhanced by the addition of the reinforcements in to metallic matrix compared to the conventional engineering materials. Improvement in strength and stiffness has been observed in most metal systems and lowering of the coefficient of friction and the wear rates have been observed by addition of CNTs in Ni, Cu and Al based composites. This paper presents the overview of the effect of addition on various reinforcements in Aluminium highlighting their merits and demerits. Effect of different reinforcement on AMCs on the machining parameters and mechanical properties like tensile strength, strain, hardness, wear and fatigue is discussed in this paper. Major issues like agglomerating phenomenon, fiber-matrix bonding and the problems related to distribution of particles are also discussed in detail. Major applications of different AMCs are also highlighted in this review.
