Abstract

Graphene shows promise as a reinforcement for metal matrix composites, though its tendency to agglomerate limits uniform distribution. This study presents a facile in-situ approach to produce graphene from graphite balls to reinforce Inconel718. The process yielded a (Ti,Nb)C/graphene core-shell structure via 3D rock milling and spark plasma sintering (SPS), enhancing graphene nanosheets (GNSs) uniformity and load transfer. Using scanning electron microscopy (SEM) and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), we analyzed the microstructure and mechanical properties of graphene nanosheets-IN718 (GNSs-IN718) composites. The 0.3GNSs-IN718 composite exhibited improved microstructure and mechanical properties, driven by grain refinement, dislocation strengthening, and load transfer, verified through molecular dynamics simulations. This approach offers new directions for metal matrix composites design in aerospace.
