The current magnetic confinement nuclear fusion power reactor concepts going beyond
ITER are based on assumptions about the availability of materials with extreme mechanical …

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

Plasma-facing materials and components in a fusion reactor are the interface between the
plasma and the material part. The operational conditions in this environment are probably …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

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 …

Owing to its high magnetic field, high power, and compact size, the SPARC experiment will
operate with divertor conditions at or above those expected in reactor-class tokamaks …

All the recent DEMO design studies for helium cooled divertors utilize tungsten materials
and alloys, mainly due to their high temperature strength, good thermal conductivity, low …

Here we show that cold rolling decreased the brittle-to-ductile transitions (BDT) temperature
of tungsten (W). Furthermore, we show that the BDT temperature correlates with the grain …

The structure and phase stability of binary tungsten-vanadium and tungsten-tantalum alloys
are investigated over a broad range of alloy compositions using ab initio and cluster …

Tungsten-based materials are considered to be one of the most promising plasma-facing
materials, but there are still many problems in practical application. Plasma-facing materials …
