A novel approach to develop aluminum matrix nano-composite employing friction stir welding technique.

Highlights: [•] AA7075/SiC nano-composite developed employing friction stir welding technique. [•] 1250rpm and 40mm/min were the optimum welding speeds. [•] Increasing rotational speed resulted in improved powders dispersion. [•] An excellent bonding between reinforcement and the matrix was observed. [•] UTS and ductility improved by up to 31% and 76.1% due to grain size refinement associated with SiC nano-particles. [ABSTRACT FROM AUTHOR]
