Material issues pose a significant challenge for the design of future fusion reactors. From a
historic point of view, the material mix used for the first wall of a fusion reactor has …

Tungsten fiber reinforced tungsten (W f/W) composite is one of the candidates to improve the
toughness of tungsten materials. Powder metallurgy is a potential method to produce W f/W …

As the interface closest to the edge plasma of a fusion reactor reacting deuterium (D) and
tritium (T), plasma-facing material (PFM) need to withstand extreme service conditions with …

In this study, AlN particles were proposed as the reinforcement to prepare Fe activated
sintered tungsten matrix composites. The results indicated that the AlN particles stably …

To overcome the brittleness of tungsten, tungsten fiber-reinforced tungsten composites (W
f/W) have been developed using an extrinsic toughening mechanism. In this work, a novel …

Even though tungsten (W) is considered to be the most favored plasma-facing material
(PFM) for nuclear fusion reactors thanks to its beneficial physical properties, its advantage …

Carbide reduces the ductility of tungsten and leads to brittle intergranular fractures. These
fractures are inevitably formed in tungsten by carbon diffusion owing to graphite mold during …

Tungsten fiber-reinforced tungsten (W f/W) has been developed to improve the fracture
toughness of W materials, as demonstrated in previous studies (2019 Nucl. Fusion 59 …

Full-densely activated sintered W (Fe) was prepared by spark plasma sintering technique.
The effects of Fe content (0∼ 1.0%(wt.%)) on relative density, microstructure and …

Tungsten is the main candidate for the plasma-facing material in future fusion reactors. To
overcome the brittleness of tungsten, tungsten fiber-reinforced tungsten (W f/W) composites …
