Manufacturing Of Aluminium Matrix Composite Using Stir Casting Method

Aluminium Matrix Composites (AMC's) are widely used in aerospace, automotive, structural and marine applications due to their high strength to weight ratio, corrosion resistance. In AMC one of constituent is aluminium or its alloy which forms a network called as matrix phase and other constituent is embedded in matrix made of harder material generally ceramic or non metallic material called as reinforcement. Various processing techniques are available for manufacturing of AMC's. Stir casting is one of the economical and extensively used methods to enhance attractive properties of AMC's. This paper presents an overview of stir casing process, process parameter and preparation of AMC using aluminium alloy as matrix phase and alumina (Al2O3) as reinforcement by varying their proportion
