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 …

Refractory alloys such as tungsten and molybdenum based alloys with high strength,
thermal/electrical conductivity, low coefficient of thermal expansion and excellent creep …

In fusion reactors, surfaces of plasma facing components (PFCs) are exposed to high heat
and particle flux. Tungsten and Copper alloys are primary candidates for plasma facing …

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 …

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 …

Under the anticipated operating conditions for demonstration magnetic fusion reactors
beyond ITER, structural and plasma-facing materials will be exposed to unprecedented …

Finding high performance plasma-facing materials (PFMs) is one of the most important and
challenging tasks for realizing the commercial application of fusion reactors. Herein, we …

The formation of helium cavities in coarse-grained materials produces hardening
proportional to the number density and size of the cavities and due to the interaction of …

Helium plasma irradiation to various metals leads to peculiar morphology changes as
forming fiberform nanostructures called fuzz when a certain set of conditions is satisfied. In …
