Tungsten is widely used as a material capable of withstanding extreme operating conditions
and is one of the candidates for use in fusion and Generation IV fission reactors. Atomistic …

Ab initio simulations are employed to assess the interaction of typical interstitial impurities
with self-interstitial atoms, dislocation loops and edge dislocation lines in tungsten. These …

By impeding dislocation motion, the irradiation-induced dislocation loops cause irradiation
hardening and further embrittlement of plasma-facing tungsten in fusion reactors, leading to …

Tungsten (W) is considered to be the most promising plasma-facing material in fusion
reactors. During their service, severe irradiation conditions create plenty of point defects in …

Neutron and heavy-ion irradiation of tungsten produces nanometer-size vacancy voids, gas-
filled bubbles and dislocation loops. These defect features can affect mechanical properties …

The prismatic dislocation loops appear in metals as a result of high-energy irradiation.
Understanding their formation and interaction is important for quantification of irradiation …

Plastic deformation of polycrystalline materials is largely controlled by the interaction
between lattice dislocations and grain boundaries. The atomistic details of these interactions …

We performed ab initio density functional theory simulations of 1 2〈 111〉 interstitial
dislocation loops, closed and open vacancy loops,〈 100〉 interstitial loops, and voids in …

Abstract The interaction of 1/2< 1 1 1> screw dislocation and point defects, including
vacancy and self-interstitial atom (SIA), was investigated by molecular dynamics (MD) …

Understanding atomic-scale mechanisms of dislocation interacting with irradiation-induced
nanosized voids is vital to predict in-service performances of nuclear components. In reality …
