Influence of Particle Feeding Methods on Processing the AA6061/SiC Metal Matrix Nanocomposites

Abstract:

Aluminum alloy 6061 reinforced with 1.0 weight percentage of Silicon Carbide (SiC) nanoparticles were fabricated using the novel ultrasonic cavitation assisted stir casting approach. Three types of nanoparticle feeding mechanisms were attempted for fabricating the metal matrix nanocomposites. The fabricated nanocomposites were subjected to tension test, hardness test and scanning electron microscopic analysis. From the tested results, it was found that feeding the particles using Al foils followed by ultrasonic cavitation proved as a suitable method for obtaining the better mechanical properties of the fabricated nanocomposites. Scanning electron microscopy analysis confirmed the uniform dispersion SiC in Al matrix by capsule feeding method. Energy dispersive spectroscopy validates the incorporation of SiC in Al matrix.
