Micro structural aspects of Aluminium Silicon Carbide Metal Matrix Composite

The role of engineering materials in the development of modern technology need not be emphasized. As the levels of technology have become more and more sophisticated, the materials used also have to be correspondingly made more efficient and effective. The increasing use of Aluminium alloy materials in structural and space applications generated considerable interest for the development of techniques to predict the response under various loading conditions. In this paper micro structural behavior of Aluminium with Silicon Carbide (grit size 60) has been studied by varying mass fractions of 5%, 10%, 15%, and 20%. In all microstructures consist of coarse grains of aluminium solid solution iron-rich (silicon carbide) inter metallic particles in the grain boundaries and this can influence the fracture behaviour.
