In future fusion devices, helium irradiation to tungsten could lead to the formation of tungsten
nanostructure, which has both pros and cons as a plasma facing component. Although the …

In order to see how hydrogen is behaving in tungsten and to understand the way bubbles
form and grow up, specimens were irradiated by hydrogen ions from room temperature to …

The formation of helium bubbles and subsequent property degradation poses a significant
challenge to tungsten as a plasma-facing material in future long-pulse plasma-burning …

Due to a lack of direct experimental results, the detailed mechanisms that govern the
blistering behavior of tungsten (W) exposed to ITER-relevant condition in nuclear fusion …

Hydrogen isotopes retention and bubbles formation are critical issues for tungsten as
plasma-facing material in future fusion reactors. In this work, the formation and growing up …

We analyze the effect of subsurface prismatic dislocation loops on the surface morphology
and helium clustering behavior of plasma-facing tungsten through the use of molecular …

Helium ion bombardment of tungsten at temperatures between approximately one third and
one half of its melting point has shown growth of nanostructures colloquially referred to as …

We used molecular dynamics to study the segregation and coalescence of helium bubbles
in tungsten. We found that, similar to the case of tungsten surface, small mobile helium …

The aim of this work is to probe the helium-induced defect production and accumulation in
40 keV He+ irradiated polycrystalline W and its alternative alloy W-5wt.% Ta using …

A usual way to estimate the amount of gas in a bubble inside a metal is to assume
thermodynamic equilibrium, ie, the gas pressure P equals the capillarity force 2 γ/R⁠, with γ …
