Performance enhancement of structural materials in extreme radiation environments has
been actively investigated for many decades. Traditional alloys, such as steel, brass and …

Prediction of material performance in fusion reactor environments relies on computational
modelling, and will continue to do so until the first generation of fusion power plants come on …

Concentrated single phase solid solutions, including medium-and high-entropy alloys,
represent a new class of materials that have recently attracted significant interest due to …

The interstitial loop is a unique signature of radiation damage in structural materials for
nuclear and other advanced energy systems. Unlike other bcc metals, two types of interstitial …

Using in situ transmission electron microscopy (TEM), we have observed nanometre scale
dislocation loops formed when an ultra-high-purity tungsten foil is irradiated with a very low …

The hyperdynamics method is a powerful tool to simulate slow processes at the atomic level.
However, the construction of an optimal hyperdynamics potential is a task that is far from …

It has long been recognized from low-temperature defect production experiments and
molecular dynamics (MD) simulations of displacement events in metals that the surviving …

Probing the mechanisms of defect–defect interactions at strain rates lower than 106 s− 1 is
an unresolved challenge to date to molecular dynamics (MD) techniques. Here we propose …

We present an empirical interatomic potential for tungsten, particularly well suited for
simulations of vacancy-type defects. We compare energies and structures of vacancy …

The evolution of many systems is dominated by rare activated events that occur on timescale
ranging from nanoseconds to the hour or more. For such systems, simulations must leave …
