High-performance reduced-activation materials are crucial for fulfillment of the promise of
fusion to provide safe, economical, and environmentally acceptable energy. Three reduced …

In fusion reactors, 14 MeV high-energy neutron irradiation of structural materials will
produce large amounts of helium and hydrogen simultaneously with displacement defects …

Three ferritic/martensitic alloys were studied to understand the synergistic effect between
single ion beam (Fe 2+), dual ion beam (Fe 2++ He 2+ and Fe 2++ H+), and triple ion beam …

The purpose of this study is to evaluate the synergistic effect of helium and hydrogen on Fe–
Cr ferritic model alloys, to provide basic understanding concerning development of fusion …

Cavity swelling, due to three-dimensional clustering of vacancies, is an undesirable isotropic
volume expansion of materials under irradiation. This phenomenon occurs above stage-III …

Accurate modeling of irradiation damage processes is important to predict materials
performance in nuclear environments. The mean-field rate theory (RT) approach has been …

The detrimental effects of hydrogen and helium on structural materials undergoing
irradiation are well documented, if not well understood. There is experimental evidence to …

Irradiations for spallation target vessels and structural materials of fusion reactors were
simulated using simultaneous triple/dual ion beams consisting of Fe3+, He+ and H+ ions or …

The reduced activation ferritic/martensitic steel F82H-IEA was studied through a systematic
set of dual (Fe 2++ He 2+) and triple (Fe 2++ He 2++ H+) ion irradiations to determine the …

The synergistic effects of displacement damage and atomic hydrogen and helium on
swelling of the ferritic/martensitic steel, F82H, has been investigated. The irradiation was …
