Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving …

In this review, we focus on the saturation microstructure that evolves during severe plastic
deformation (SPD). These nanocrystalline or ultrafine-grained microstructures consist …

Single-phase body-centered cubic (bcc) refractory medium-or high-entropy alloys can retain
compressive strength at elevated temperatures but suffer from extremely low tensile ductility …

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 …

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 …

The fact that the bulk nanostructured metallic materials have been one of the hottest topics in
materials science in the last decade clearly shows their growing importance as future …

Tungsten is a refractory metal with the highest melting temperature and density of all metals
in this group. These properties, together with the high thermal conductivity and strength …

The suitability of high-strength ultrafine and nanocrystalline materials processed by severe
plastic deformation methods and aimed to be used for structural applications will strongly …

This work discusses the response of ultrafine-grained tungsten materials to high-flux, high-
fluence, low energy pure He irradiation. Ultrafine-grained tungsten samples were exposed …

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