Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

In 1959 the Journal of Nuclear Materials (JNM) was founded and is now celebrating its
Diamond Anniversary year. The present paper is part of a series in which single JNM …

Displacement damage, through heavy ion irradiation was studied on two tungsten grades
(coarse grained tungsten (CGW) and nanocrystalline and ultrafine grained tungsten (NCW)) …

The accumulation of defects and in particular He bubbles, can have significant implications
for the performance of materials exposed to the plasma in magnetic-confinement nuclear …

Tungsten, the primary material under consideration as the divertor material in magnetic-
confinement nuclear fusion reactors, has been known for the last decade to form'fuzz'—a …

We have investigated the effects of helium ion irradiation energy and sample temperature on
the performance of grain boundaries as helium sinks in ultrafine grained and nanocrystalline …

Large-scale molecular dynamics simulations of post-implantation helium behavior in plasma-
facing tungsten single crystals reveal orientation-dependent depth profiles, surface evolution …

This work discusses the response of ultrafine-grained tungsten materials to high-flux, high-
fluence, low energy pure He irradiation. Ultrafine-grained tungsten samples were exposed …

Crystal defects generated during irradiation can result in severe changes in morphology and
an overall degradation of mechanical properties in a given material. Nanomaterials have …

Nanocrystalline metals are postulated as radiation resistant materials due to their high
defect and particle (eg Helium) sink density. Here, the performance of nanocrystalline iron …
