Thermal Stability and Deformation Mechanisms in Graphene- or Silicene-Reinforced Layered and Matrix Metallic Composites

Abstract

The methods of increasing the structural and thermodynamic stability of the interface states in metal/2D crystal interfaces are considered. These states determine the main characteristics of layered and matrix metal/graphene and metal/silicene nanocomposites (M/2D–G and M/2D–Si, were M = Al, Mg, Ir, Pd, Ru, Ni, Ti, Ag), which can be fabricated by the dispersion of graphene or silicene nanoparticles in melts and by an additive 3D typing technology (PVD, CVD) with layer-by-layer growth of metallic crystalline or amorphous nanofilms on preliminarily deposited graphene or silicene layers (from one to several layers). The experimental data and the results of combined calculations of the structure, the unique electronic properties, and the mechanisms of ultrahigh strength of the nanocomposites, which were performed in terms of the density functional theory, are systematically analyzed.
