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

含石墨烯夹杂物的双峰材料塑性变形机理的变化

摘要—建立了改变石墨烯夹杂物双峰材料塑性机制的理论模型。在该模型的框架内，已经进行了有关塑性变形从双晶材料固有的纳米晶和/或超细晶粒基体到粗晶粒相转变的理论研究。特别地，对从孪晶变形到晶格滑动的过渡进行了理论描述。计算了具有双峰结构的石墨烯-金属复合材料的塑性变形机制的能量参数和临界应力
