Publication date: Available online 1 August 2015 Source: Journal of Asian Ceramic Societies Author(s): Pardeep Sharma, Satpal Sharma, Dinesh Khanduja The present research work focuses on the production of aluminium (AA6082-T6) matrix composites reinforced with various weight percentage of silicon nitride particles by conventional stir casting route. The percentage of reinforcement is varied from 0 wt.% to 12 wt.% in a stage of 3%. The microstructures and mechanical properties of the fabricated aluminium matrix composites are investigated. The scanning electron microstructure images reveal the presence of Si 3 N 4 particles in the aluminium matrix. The distribution of Si 3 N 4 particles has also been recognized with X-ray diffraction technique. The mechanical properties such as ultimate tensile strength and hardness have improved at the cost of reduction in ductility with increase in weight percentage of silicon nitride particulates in the aluminium metal matrix. The density and porosity of the composites also show an increasing trend with increase in volume fraction of Si 3 N 4 particles in the aluminium matrix.
