The present research article discusses fabrication, micro structural investigation and mechanical behavior of Al6061/(Si3N4+SiC) composite. High strength at the cost of toughness is very often in metallic composites reinforced with hard ceramic particles. Aerospace, automobile and marine industries demand tough and high strength materials. Simultaneous improvement in strength and fracture toughness is the major concern of the current study. To attain the objective, two reinforcement particles of dissimilar shape and sizes were chosen. Small quantity of micron sized SiC particles and elongated rodlike submicron Si3N4 particles were utilized to reinforce the Al6061 alloy matrix. Aforementioned combination of reinforcement and aluminium matrix is unique in itself. Three different compositions including base alloy were fabricated by two step stir casting method for analysis. For micro structural characterization, an optical microscope and FESEM (field emission scanning electron microscope) with EDS were used. Fractured surface of the tensile test was also investigated by FESEM.
