EUROFER97 specimens Al-base coated using different processes, either chemical vapour deposition or electroplating, were oxidised at 980 °C for 60 minutes and 760 °C for 90 minutes to understand whether this 2-step oxidation process could provide a suitable oxide layer able to offer both corrosion protection and a tritium permeation barrier. The…

We recast the Howie-Whelan equations for generating simulated transmission electron microscope (TEM) images, replacing the dependence on local atomic displacements with atomic positions only. This allows very rapid computation of simulated TEM images for arbitrarily complex atomistic configurations of lattice defects and dislocations in the dyna…

The effect of water chemistry, surface condition, pH moderator (LiOH vs. KOH), and Zn addition was investigated at 300 °C on the oxidation behaviour of reduced activation ferritic martensitic (RAF/M) EUROFER-97. EUROFER-97 is the proposed material for the water-cooled breeder blanket (WC-BB) section of DEMO, but its behaviou…

The self-passivating yttrium-containing WCr alloy has been developed and researched as a potential plasma-facing armour material for fusion power plants. This study explores the use of yttria (Y2O3) powders instead of yttrium elemental powders in the mechanical alloying process to assess their applicability in this material. Fabricated through f…
