The effect of grain boundaries and the crystal surface on the deformation and strength
properties of nanocrystalline and nanosized materials, primarily metals, is reviewed. Basic …

A model is developed for the plastic deformation of nanocrystalline materials in terms of the
evolution of a spatial grid of disclinations located at the triple junctions of grains. Plastic …

Structural mechanisms and features of brittle and quasi-brittle fracture of nanocrystalline
materials are theoretically analyzed. The role of size effects and internal stresses caused by …

materials are theoretically analyzed. The role of size effects and internal stresses caused by …

A high-rate plastic deformation of fine-grained materials has been considered as a result of
competing processes of dislocation gliding in the grains and grain-boundary sliding. A …

A new structural classification of nanomaterials is proposed; it is based on the different
natures of structural nanoelements that radically change the properties of nanomaterials …

This review is devoted to the effect of grain boundaries on the deformational and strength
properties of poly-, micro-, and nanocrystalline materials (predominantly metals). The main …

Atomic mechanisms of the beginning of plastic deformation and failure initiation in
nanoparticles of bcc transition metals are presented in this report. It is shown that strength …

A new paradigm of hardening of nanocrystals is proposed based on the competing influence
of various mechanisms of plastic deformation, ie, dislocation sliding and grain-boundary slip …

We provide an overview of theoretical models of plastic deformation processes in
nanocrystalline materials. The special attention is paid to the abnormal Hall-Petch …
