Simulation of structural and electronic properties of amorphous tungsten oxycarbides [PDF]

open access: yes, 2012
Electron beam-induced deposition with tungsten hexacarbonyl W(CO)6 as precursors leads to granular deposits with varying compositions of tungsten, carbon and oxygen. Depending on the deposition conditions, the deposits are insulating or metallic.

On the prediction and monitoring of tungsten prompt redeposition in tokamak divertors

open access: yesNuclear Materials and Energy, 2021
As net erosion of tungsten plasma-facing components in tokamak divertors is strongly reduced by tungsten prompt redeposition, predicting and monitoring tungsten prompt redeposition is crucial to estimate the lifetime of tungsten PFCs and the source of ...

Precipitation at Tungsten/Tungsten Interfaces in Tungsten–Nickel–Iron Heavy Alloys [PDF]

open access: yesPowder Metallurgy, 1986
AbstractA study of precipitation at the tungsten grain boundaries in the tungsten–nickel–iron ternary alloy system has been undertaken. Scanning and transmission electron microscopy techniques have been used to study the effect of various post-sintering heat treatments on the precipitation reaction.
