Abstract
Oxide-dispersion-strengthened (ODS) steels are candidate structural materials for future fusion reactors. For this application, the coarsening behavior of the yttria-based strengthening oxygen-rich nanoparticles is of particular importance. This paper reports on the coarsening behavior of oxygen-rich nanoparticles in two Fe–14Cr–2W–(0.1–0.3)Ti base alloys after annealing at 1200 °C up to 100 h. Nanoparticles with and without Ti enrichment are investigated, and it is shown that nanoparticles that do not contain Ti coarsen at the same rates as those with Ti.
