The lifetime of tungsten (W) monoblocks under fusion conditions is ambivalent. In this work,
the microstructure dependent mechanical behaviour of pulsed high heat flux (HHF) exposed …

Recrystallization is a critical issue in ITER and future fusion devices as it strongly
deteriorates the properties and serving life of tungsten divertor armor. In this work, we …

Powder metallurgical processing of Tungsten (W) followed by thermomechanical treatment,
including rolling and stress relief (SR) heat treatment, is a candidate fabrication process for …

Linear plasma devices represent an essential tool for nuclear fusion research, whereby
understanding crucial aspects related to plasma-wall interactions or edge plasma …

Highlights (i) EBSD, nanoindentation and AFM have been used to understand the post-
plasma exposure recrystallization behaviour of W.(ii) These techniques have shown that …

Helium plasma is known to affect recrystallization in tungsten, with lower temperatures
during plasma exposure leading to slower crystal grain growth. To understand why this …

The study of the recrystallization resistance of engineering grade tungsten (W) prior to and
after neutron irradiation as well as subsequent thermal annealing provides valuable insight …

Grazing-incidence small-angle x-ray scattering (GISAXS) and thermal desorption
spectroscopy (TDS) were used to study the thermal evolution of helium (He) bubbles in …

Abstract Knowledge of a material's thermal stability under extreme synergistic particle and
heat loads is crucial for develo** high performance reactor materials. In this work, the …

One of the R&D focus in the European fusion energy program is to establish a physical and
technological basis for reliable power exhaust during entire operational situations of a …
