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 hig h 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 emb edded in matrix made of harder material generally ceramic or non metallic material called a s 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,proces s parameter and preparation of AMC using aluminium alloy as matrix phase and alumina (Al 2 O 3) as reinforcement by varying their proportion.
