Abstract

Aluminium Hybrid Metal Matrix Composites (AHMMCs)have evoked a keen interest in recent times for potential applications in aerospace and automotive industries owing to their superior strength to weight ratio and high temperature resistance. In the past few years the global need for low cost, high performance and good quality materials has caused a shift in research from monolithic to composite materials. Reinforcements like particulate alumina, silicon carbide, graphite, fly ash, rice husk ash (RHA)etc can easily be incorporated in the melt using cheap and widely available stir casting method. The present review deals with the characterization of aluminium based hybrid composites developed by stir casting for advanced applications. The potential of a wide range of secondary reinforcements has been explored for the development of Aluminium Hybrid Metal Matrix Composites (AHMMCs) and the application area of these composites has been proposed. The focus is on the optimization of parameters for various properties of composites. Further, the influence of reinforcement's type and contents on the material properties has also been reviewed and discussed.
