Graphene has been reported to be a promising nanofiller in fabricating advanced metal matrix composites. Graphene nanosheets (GNSs) have been incorporated into an aluminium matrix composite using mechanical milling and hot pressing in the current study. The SEM observation shows that aluminium particles are firstly flattened into flakes, and then fractured/ rewelded into equiaxed .
