This article presents our take on the area of bulk ultrafine-grained materials produced by
severe plastic deformation (SPD). Over the last decades, research activities in this area have …

Disclinations together with dislocations represent a class of linear defects in solids.
Disclinations are characterized by typical singularities and the property of multi-value of the …

Materials based on nanometer-sized structural elements exhibit unique electronic, optical,
magnetic, and mechanical properties, opening up a range of new applications (1, 2). The …

A thin film tensile technique with in situ atomic-scale observations was developed to directly
characterize the atomic-scale plastic deformation mechanisms and fracture process of …

It seems there is no special need to comment on the term'nanostructure'now, when one often
meets the'nano'words not only in scientific journals but even in newspapers. Moreover …

Aone-step'theory based on Pitsch distortion is proposed to explain the continuity between
the orientations of the Kurdjumov–Sachs (KS), Nishiyama–Wassermann (NW) and Pitsch …

Nanostructural evolution of cementite lamellae in pearlitic steel wires subjected to cold
drawing remains elusive, making it difficult to understand the origin of remarkable ductility in …

A theoretical model is suggested which describes the generation and evolution of nanoscale
cracks (nanocracks) at triple junctions of grain boundaries in deformed nanocrystalline …

Theoretical models are suggested that describe the effects of stress-driven migration of grain
boundaries (GBs) on both the formation of nanoscale cracks (nanocracks) and the growth of …

An overview of recent achievements of the disclination approach in mechanics and physics
of solids is given and the use of disclination modeling in materials science is demonstrated …
