Abstract: Constructing a laminated structure in metal matrix composites working as a promising approach to simultaneously enhance strength and toughness. Nevertheless, the deformation behavior of individual grains within such laminated composites remains largely unexplored. In this study, graphene nanosheets (GNSs) reinforced copper (Cu) matrix laminated composites were fabricated through electrophoretic deposition, vacuum hot-press sintering, and hot rolling. The mechanical properties were examined via room temperature tensile testing, while microstructure and texture evolution were investigated quasi-in-situ using SEM-EBSD and neutron diffraction techniques. Additionally, Visco-plastic Self-Consistent (VPSC) modeling was utilized to simulate texture evolution during tension, shedding light on the deformation mechanisms within the laminated GNSs/Cu composites. The findings revealed that the grains in the GNSs/Cu laminated composites deformed independently without accommodating strains of grains in adjacent Cu layers. This deformation mode was further confirmed by observations on the RD-ND plane of the fractured GNSs/Cu sample. The insights garnered from this study elucidate the deformation mechanism of laminated GNSs/Cu composites and offer valuable guidance for optimizing the design of advanced metal matrix composites.
