Model of Enhanced Strength and Ductility of Metal/Graphene Composites with Bimodal Grain Size Distribution

A model is proposed that describes plastic deformation in metal/graphene composites with a bimodal grain size distribution of the metallic matrix. Within the model, dislocation pile-ups are generated in large grains at Frank–Read sources, and their stresses promote dislocation motion within the nano...
