Ductile rupture in metals is a phenomenon that affects a wide range of applications from
forming of automotive body panels to failure of pressure vessels. The incipient stage …

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

The evolution mechanisms of grain boundaries and dislocations, including grain
morphology, grain boundary structure, and dislocation motion during plastic deformation in …

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

Forming alloys with impurity elements is a routine method for modifying the properties of
metals. An alternative approach involves the incorporation of interfaces into the crystalline …

Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

Nano-grained (NG) metals are believed to be strong but intrinsically brittle: Free-standing
NG metals usually exhibit a tensile uniform elongation of a few percent. When a NG copper …

A material strength depends on its microstructure, which in turn, is controlled by an
engineering process. Strengthening mechanisms like work hardening, precipitate, and grain …

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 …

Focusing on nanocrystalline (nc) pure face-centered cubic metals, where systematic
experimental data are available, this paper presents a brief overview of the recent progress …
