Heterostructured (HS) materials are a new class of materials that are composed of
heterogeneous zones with dramatically different (> 100%) mechanical or physical …

Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1–
100 nm. Contrary to coarse-grained metals, which become more difficult to twin with …

The mechanical properties of nanocrystalline materials are reviewed, with emphasis on their
constitutive response and on the fundamental physical mechanisms. In a brief introduction …

Nanocrystalline solids, in which the grain size is in the nanometre range, often have
technologically interesting properties such as increased hardness and ductility …

Various factors affect the performance of electrical contacts, including tribological,
mechanical, electrical, and materials aspects. Although these behaviors have been studied …

A bulk nanocrystalline (nc) pure copper with high purity and high density was synthesized by
electrodeposition. An extreme extensibility (elongation exceeds 5000%) without a strain …

We review the results of recent molecular-dynamics simulations of the structure and
deformation behavior of nanocrystalline materials, ie, polycrystalline materials with a grain …

Molecular-dynamics computer simulations of a model Ni nanocrystalline sample with a
mean grain size of 12 nm under uniaxial tension is reported. The microscopic view of grain …

Nanocrystalline metals, ie, metals in which the grain size is in the nanometer range, have a
range of technologically interesting properties including increased hardness and yield …

It is now recognized that grain boundary sliding (GBS) is often an important mode of
deformation in polycrystalline materials. This paper reviews the developments in GBS over …
