| Abstract |
A theoretical model for changing the plasticity mechanism in bimodal materials with graphene inclusions has been developed. Within the framework of the model, a theoretical study on the transition of plastic deformation from a nanocrystalline and/or ultrafine-grained matrix to the coarse-grained phase, which is inherent to bimodal materials has been performed. In particular, a theoretical description of the transition from deformation by twinning to lattice slip is made. The energy parameters and critical stresses characterizing the change in the mechanism of plastic deformation for graphene-metal composites with a bimodal structure are calculated |
