Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and
nanostructured materials with large densities of lattice defects. This field, also known as …

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 …

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 …

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

Although grain boundaries can serve as effective sinks for radiation-induced defects such as
interstitials and vacancies, the atomistic mechanisms leading to this enhanced tolerance are …

The mechanical behavior of nanolaminates is dominated by interfaces that act as sources,
barriers, and preferred sites for storage and dynamic recovery of glide dislocations. In this …

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 act as obstacles to slip and sinks for radiation-induced defects. Hence,
nanolayered composites that contain a large volume fraction of interfaces provide over an …

The accumulation of defects and in particular He bubbles, can have significant implications
for the performance of materials exposed to the plasma in magnetic-confinement nuclear …

Sputter-deposited Cu/V nanolayer films with individual layer thickness, h, varying from 1 to
200nm were subjected to helium (He) ion irradiation at room temperature. At a peak dose …
