| Abstract Scope |
Hastelloy N is a promising candidate for structural applications in molten salt reactors, due to its durability under exposure to molten salt and stress at elevated temperatures. To further improve mechanical performance, Y-Ti rich nanoscale oxides can be added to support the material through dispersion strengthening. For this study, ODS Hastelloy N is produced through the industrial scale consolidation method hot isostatic pressing. Feedstock was produced through electrode induction gas atomization, enabling direct addition of oxide forming additions during the atomization process. Additional processing steps, such as mechanical alloying and hot rolling are added to the manufacturing route. Effects of processing route as well as oxide additions on grain structure and mechanical performance were observed. The manufacturing route that led to the strongest material was corroded in molten LiCl and KCl and its microstructure was evaluated via transmission electron microscopy to better understand its behavior in a molten salt environment. |
