Nucleation and growth mechanisms of interfacial carbide in graphene nanosheet/Al composites

The interface reaction is the focus of interface control in the graphene/Al composites, but its evolution processes are still unclear. The present work revealed the nucleation and growth mechanisms of the interfacial reaction product, aluminum carbide (Al4C3), in the graphene nanosheet (GNS)/Al composites. The nucleation of Al4C3 was found to mainly start at the open edge of GNSs due to the high chemical reactivity, and the formed Al4C3 was...
