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 …

High strength of materials usually comes with low ductility due to the lost or short-lived strain
hardening. Here, we uncover a sequentially-activated multistage strain hardening (SMSH) …

Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

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

Nanostructured materials contain an extremely high density of interfaces. The properties of
these materials when exposed to extreme conditions of radiation dose, stress, deformation …

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 …

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 …

Despite rosy prospects, the use of nanostructured metals and alloys as advanced structural
and functional materials has remained controversial until recently. Only in recent years has a …

Ductility is one of the most important mechanical properties for metallic structural materials. It
is measured as the elongation to failure of a sample during standard uniaxial tensile tests …
