This document discusses the mechanical behavior of aluminum based metal matrix composites reinforced with silicon carbide and alumina. It provides an introduction to metal matrix composites and their properties. The objective is to fabricate an aluminum matrix composite through stir casting and evaluate its mechanical properties. A literature review covers topics like microstructure and corrosion behavior of aluminum-silicon carbide composites, wear properties of aluminum composites, and aging behavior of silicon nitride reinforced aluminum composites.
