A study on microstructure of aluminium matrix composites

AbstractThis work focuses on the effect of graphite particles addition on the microstructure of Al6082 metal matrix composites manufactured by conventional stir casting process. The reinforcement content was varied from 0% to 12% in a step of 3%. The microstructures of the manufactured composites were analyzed by scanning electron micrographic test. Elemental mapping of the Al6082+12% Gr reinforced composite was carried out to see the different elements present with their amount. Different elements present in the manufactured composites were verified by X-ray diffraction technique to justify the elemental map analysis. The result of this microstructural investigation revealed that a non-uniform distribution of graphite particles takes place at all weight percentages of graphite reinforcement
