Effect of SiC Nanoparticles on the Dispersion of Multiwalled Carbon Nano Tubes in AA 5083 by Stir Casting Technique

Abstract Multi Walled Carbon Nanotubes (MWCNT) exhibit outstanding thermal, electrical and mechanical properties. These properties of MWCNTs motivate in the fabrication of advanced nanocomposites for a significant increase in one of these properties. In this study, Aluminum Alloy 5083 was reinforced with 5% percentage of SiC and 0, 1.66, 3.33 % of Multi-walled Carbon Nanotubes (MWCNTs). The reinforcement was done by stir casting route. The cast thus produced were tested for their tensile strength. The tensile strength increased by 18%. The distribution of the two reinforcements was analyzed by obtaining SEM micrographs of the various casts. XRD was done to obtain the various elemental compositions. There were no intermetallic compounds formed. The interactions between SiC and MWCNT was studied.
