Scientific understanding of any kind of radiation effects starts from the primary damage, ie
the defects that are produced right after an initial atomic displacement event initiated by a …

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 …

Grain boundary (GB) migration plays an important role in modifying the microstructures and
the related properties of polycrystalline materials, and is governed by the atomistic …

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

Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving …

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 …

Unwanted exposures to high-energy or ionizing radiation can be hazardous to health.
