Abstract

In the present study, Al6061/zirconium carbide surface composites have been developed using the friction stir processing method. The volume fraction of the zirconium carbide particles was varied as 3%, 6% and 9%. The developed composites were characterized using optical microscopy, X-ray diffraction and scanning electron microscopy. Micrographs revealed uniform distribution of zirconium carbide particles, and addition of zirconium carbide particles was found to improve hardness and tensile properties of Al6061 alloy. Corresponding strengthening mechanisms have been discussed and associated with the microstructural studies. Fractographic analysis was found to show a reduction in ductility with increase in addition of zirconium carbide particles.
