Stir casting & processing of aluminum matrix composites

Abstract

Aluminium Matrix Composites have potential applications in Aerospace and Automotive industries. Their light weight structure, high corrosion resistance and superior mechanical properties make them a choice candidate in higher end applications. Aluminiummatrix composites materials can be produced by many different techniques. By altering the manufacturing method, the processing and the finishing, as well as by the form of the reinforcement components added, it is possible to obtain different characteristic profiles, although the same composition and same amounts of the components are involved. This paper focuses on the processing of various aluminium alloy composites by varying different parameters using stir casting technique. Because of the presence of ceramic reinforcements, processing these metal matrix composites is challenging and requires better alternative techniques.
