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

Nanostructured metallic materials having nanocrystalline and ultrafine-grained structures
show exceptional mechanical properties, eg superior strength, that are very attractive for …

Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Deformation twinning is rarely found in bulk face-centered cubic (FCC) alloys with very high
stacking fault energy (SFE) under standard loading conditions. Here, based on results from …

Bulk nanostructured (NS) materials processed by severe plastic deformation (SPD) have
received considerable attention for several decades. The physical origin of this processing …

Nanostructured metals are generally unstable; their grains grow rapidly even at low
temperatures, rendering them difficult to process and often unsuitable for usage. Alloying …

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 …

During the last decade, equal-channel angular pressing (ECAP) has emerged as a widely-
known procedure for the fabrication of ultrafine-grained metals and alloys. This review …

This article reviews recent basic research on two classes of twins: growth twins and
deformation twins. We focus primarily on studies that aim to understand, via experiments …
