The “void lattice” formed by periodic arrangements of voids, usually replicating the symmetry
and crystallographic orientation of the host matrix, is an interesting phenomenon in materials …

We have systematically investigated the influence of carbon (C) impurity on the aggregation,
migration, and annihilation of neutron irradiation defects as well as the mechanical …

Zirconium (Zr) alloys have been widely used as structural materials for in-core components
in water-cooled nuclear reactors. During normal operation, these materials are exposed to a …

Modeling the evolution of radiation-induced defects is important for finding radiation-
resistant materials, which would be greatly appreciated in nuclear applications. We apply …

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

The vacancies produced in high energy collision cascades of irradiated tungsten can form
vacancy clusters or prismatic vacancy dislocation loops. Moreover, vacancy loops can easily …

Molecular dynamics (MD) cascade simulations of single crystal and five bi-crystal structures
in bcc tungsten (W) are conducted to investigate the role of grain boundaries (GBs) on defect …

Over the last decade, molecular dynamics simulations of displacement cascades have
revealed that glissile clusters of self-interstitial crowdions are formed directly in cascades …

We have performed a systematic molecular dynamics investigation of the effects of overlap
of collision cascades in tungsten with pre-existing vacancy-type defects. In particular, we …

To study the effect of temperature on the evolution of irradiation-induced cavities in tungsten,
ITER Grade Product tungsten was characterised using transmission electron microscopy …
