Helium (He) bubbles are typical radiation defects in structural materials in nuclear reactors
after high dose energetic particle irradiation. In the past decades, extensive studies have …

Density functional theory models developed over the past decade provide unique
information about the structure of nanoscale defects produced by irradiation and about the …

Swelling associated with the formation and growth of cavities is among the most damaging
of radiation-induced degradation modes for structural materials in advanced nuclear reactor …

The effect of hydrogen and helium interaction, especially H–He ratio, on the irradiation
behavior of nuclear materials has not yet been resolved. However, this is an important basis …

The macroscopic behavior of polycrystalline materials is influenced by the local variation of
properties caused by the presence of impurities and defects. The effect of these impurities at …

Tungsten (W) and W-based alloys have been considered as promising candidates for
plasma-facing materials (PFMs) in future fusion reactors. The formation of rhenium (Re)-rich …

The microstructure of materials and its evolution are influenced by the interaction of point
defects with the solute atoms, already present or introduced by irradiation. Electronic …

In this study, we employ transmission electron microscope (TEM) to analyze radiation
defects in helium (He) and krypton (Kr) ions implanted bulk and thin-foil tungsten. For bulk …

Abstract Density Functional Theory calculations and Molecular Dynamics with a recently
developed potential for W–He were used to evaluate the thermal stability of helium–vacancy …

We have constructed W–He and H–He analytical bond-order potentials for a W–H–He
system. In combination with the previously self-developed W–H potential [X.-C. Li, X. Shu, Y …
