Abstract Scope |
Development of materials capable of surviving extreme irradiation and thermal environments is critical to adoption of advanced nuclear reactors for producing safe, reliable C-free energy. Oxide dispersion strengthened (ODS) ferritic stainless steels show excellent promise for surviving these extreme conditions while maintaining oxidation and creep resistance under harsh conditions. Commercial adoption of ODS ferritic alloys has been limited due to the high costs of mechanical alloying (MA) for producing these alloys. Gas atomization reaction synthesis (GARS) production of ODS precursor powders with vacuum hot pressing and hot rolling is a simplified transformative approach for creating structural ODS alloy sheet/plate for nuclear reactors. This talk overviews new work at Ames Laboratory intended to produce ferritic ODS alloy sheet from GARS precursor powders with uniform control over alloying elements and oxide dispersoids after exchange reaction annealing to enable cost-effective production of ODS parts.
