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 …

Proposed fusion and advanced (Generation IV) fission energy systems require high-
performance materials capable of satisfactory operation up to neutron damage levels …

Positron is the only probe that can detect individual atomic vacancies and small and large
vacancy clusters induced by irradiation with remarkable sensitivity, providing information …

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 …

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 …

Reduced activation ferritic martensitic (RAFM) and oxide dispersion strengthened (ODS)
steels are the most promising candidates for fusion first-wall/blanket (FW/B) structures. The …

This article summarizes the recent progress on develo** a class of potentially
transformational structural materials called nanostructured ferritic alloys, which are leading …

The key to perfect radiation endurance is perfect recovery. Since surfaces are perfect sinks
for defects, a porous material with a high surface to volume ratio has the potential to be …

Nanocrystalline (NC) metals are stronger and more radiation-tolerant than their coarse-
grained (CG) counterparts, but they often suffer from poor thermal stability as nanograins …
