Tungsten, the primary material under consideration as the divertor material in magnetic-
confinement nuclear fusion reactors, has been known for the last decade to form'fuzz'—a …

The change in surface damage/microstructures and its effects on the hydrogen (H)
isotope/helium (He) dynamic behavior are the key factors for investigating issues of tungsten …

Finding high performance plasma-facing materials (PFMs) is one of the most important and
challenging tasks for realizing the commercial application of fusion reactors. Herein, we …

Helium plasma irradiation to various metals leads to peculiar morphology changes as
forming fiberform nanostructures called fuzz when a certain set of conditions is satisfied. In …

Nanotendril “fuzz” will grow under He bombardment under tokamak-relevant conditions on
tungsten plasma-facing materials in a magnetic fusion energy device. We have grown …

Tungsten, the material used in the plasma-facing components (PFCs) of nuclear fusion
reactors, develops a fuzz-like surface morphology under typical reactor operating conditions …

Growth of helium (He) bubbles with different initial sizes in tungsten (W) has been
investigated by performing molecular dynamics simulations. Based on the simulation results …

Due to their balance of strength, ductility and toughness, liquid-phase sintered tungsten
heavy metal alloys (WHAs) are considered to be an attractive alternative to monolithic …

Due to the sharp surface cracks resulting from high and cyclic thermal loads, fracture
toughness is a crucial property for fusion divertor materials. Tungsten heavy alloys (WHA) …

Surface free energy has been hypothesized as the cause behind the experimental evidence
(Parish et al., 2014) of a strong correlation between crystallographic orientation and surface …
