Distribution of Tritium in the Near Surface of Candidate Structural Materials for Fusion Reactors. Type 304L Stainless Steel, Inconel, Hastelloy, Eurofer-97, Oxide Dispersion-Strengthened Alloy 14YWT Open
Five different candidate structural materials for fusion have undergone pure tritium gas soaking at room temperature and at 310-mbar(a) pressure. The tritium uptake on the surface and in the bulk of the alloys has been analyzed using surfa…

Influence of Heat Treatments on the Near-Surface Tritium Concentration Profiles Open
Austenitic stainless steel, type 316, absorbs significant quantities of tritium into the near surface (1 μm into the bulk. Furthermore, this effect increases with increasing temperature. Second, depletion of tritium from the near surface d…
