There remain some drawbacks of mechanical properties of W materials as a plasma facing
material (PFM) for fusion reactor divertors, which are low temperature brittleness, high …

Abstract Tungsten–tantalum (W-Ta) alloys containing 1–5% Ta were developed for fusion
reactor applications. For the mechanical properties and resistance against recrystallization …

The divertor target components for the Chinese fusion engineering test reactor (CFETR) and
the future experimental advanced superconducting tokamak (EAST) need to remove a heat …

The plasma facing unit (PFU) of ITER divertor is repeatedly exposed to high heat flux, and a
reliable heat removal capability is crucial for its adequate performance. The cyclic high heat …

Tungsten-based materials are the most prospective candidates for the plasma facing
components for future fusion devices, such as DEMO. In order to improve their properties …

The interaction of hydrogen (H) with dislocations in tungsten (W) must be understood in
order to model the mechanical response of future plasma-facing materials for fusion …

The degradation behavior of the ITER divertor under the cyclic high heat flux loading has
been varied in the previous studies, which would be induced by the intrinsic difference in the …

Due to the inherently limited ductility at room temperature, cracks were almost inevitable in
additively manufactured tungsten (W). In this study, we propose a novel W-5 wt.% Re-C …

Calibration-free laser-induced breakdown spectroscopy (CF-LIBS) was applied to tungsten
(W)-tantalum (Ta) alloy and W-rhenium (Re) alloy. In the W-Ta alloy measurement, an …

Tungsten components inside fusion reactors are subjected to extreme conditions, including
an exceptionally high heat flux. This loading induces high stress levels, that may lead to …
