Investigation on Mechanical Properties of Aluminum Metal Matrix Composites - A Review

Abstract

Light weight Aluminium alloys are extensively used in aircraft, supercars, and marine applications owing to its corrosion resistance and density. However, the mechanical properties like stiffness, tensile properties and tribological characteristics are far inferior than steels and titanium alloys. The tribomechanical properties of existing Aluminium alloys can be improved by adding suitable reinforcement agent and heat treatment techniques. In this review, effect of different reinforcement on mechanical properties and tribological characteristics of Aluminium Metal Matrix Composites (AMMC) were discussed in detail. Also, various fabrication processing techniques like solid state processing, liquid state processing and in-situ processing on tribological behavior of AMMC is discussed.
