摘要: Abstract An overview of micromechanical models strength and deformation behaviour nanostructured ultrafine grained metallic materials is presented. Composite nanomaterials, polycrystal plasticity based models, grain boundary sliding, the effect non-equilibrium boundaries nanoscale properties are discussed compared. The examples incorporation peculiar nanocrystalline effects (like large content amorphous or semi-amorphous phase, partial dislocation GB emission/glide/GB absorption mechanism, diffusion deformation, etc.) into continuum mechanical approach given. possibilities using to explore ways improving by modifying their structures (e.g., dispersion strengthening, creating boundaries, varying size distributions gradients) discussed.
