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 …

The tungsten (W) material in the high heat flux regions of the ITER divertor will be exposed
to high fluxes of low-energy particles (eg H, D, T, He, Ne and/or N). Combined with long …

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 …

In-situ irradiations with 30 keV He+ were performed on tungsten in an investigation of the
influences of irradiation temperature and fluence, pre-existing dislocation and sample …

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 …

Nanocrystalline metals are considered highly radiation-resistant materials due to their large
grain boundary areas. Here, the existence of a grain size threshold for enhanced irradiation …

Increasing the density of sinks such as grain boundaries and interfaces for irradiation-
induced defects and implanted ions has been demonstrated to be an effective way to …

A wet-chemical method combined with spark plasma sintering was used to prepare a W–
Y2O3 alloy. High-temperature tensile tests and nano-indentation microhardness tests were …

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 …
