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 …

In-situ irradiations with 30 keV He+ were performed on tungsten in an investigation of the
influences of irradiation temperature and fluence, pre-existing dislocation and sample …

In this study, we employ transmission electron microscope (TEM) to analyze radiation
defects in helium (He) and krypton (Kr) ions implanted bulk and thin-foil tungsten. For bulk …

Nanocrystalline (NC) W metals and alloys often exhibit higher radiation tolerance and
strength than their coarse-grained counterparts. However, their thermal stability is low …

In this study, the nanocrystalline NbMoTaW and NbMoTaWV refractory multi-principal
element alloy (RMPEA) films were selected for the research of low-energy (50 eV), high-flux …

Molybdenum (Mo) is considered as a promising plasma-facing material, which is expected
to be used in the manufacture of critical components for the neutral beam injection (NBI) …

Tungsten (W) is the material of choice for the thermal nuclear fusion reactors of the future. In
this research, pure W (PW) and WY 2 O 3 alloys made by the SWIP (Southwestern Institute …

Tungsten is the preferred material for the first wall. In this paper, W-0.5% wt Y 2 O 3 was
selected for the exposure test of helium plasma, so that fuzz tendrils of considerable …

In this investigation, TiN-reinforced W–Ti alloys were fabricated through spark plasma
sintering of milled TiH 2 powders and micro-sized W powders. TiH 2 powder was used to …

W and W-5wt% Re alloy were irradiated by 50 keV helium ions at RT, 200° C, 350° C and
500° C to investigate the influence of temperature on the microdefects and surface …
