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 …

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 …

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

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

Designing a material from the atomic level to achieve a tailored response in extreme
conditions is a grand challenge in materials research. Nanostructured metals and …

High strength and high conductivity (HSHC) Cu alloys are widely used in many fields, such
as high-speed electric railway contact wires and integrated circuit lead frames. Pure Cu is …

The dependence of the width of void-denuded zones (VDZs) on grain boundary (GB)
characters was investigated in Cu irradiated with He ions at elevated temperature …

Interfaces are good traps for implanted He, but are also susceptible to He-induced
embrittlement. Better understanding of the mechanisms of He interactions with interfaces …

Nanoindentation was used to measure hardness before and after room temperature He ion
implantation on sputter-deposited V/Ag multilayers of different layer thickness as well as …
