| Abstract Scope |
Due to their high strengths at elevated temperatures and corrosion resistance to molten salts, nickel-based alloys are desired for structural components in molten salt reactors. For these types of alloys, there are multiple mechanisms used to increase mechanical performance, such as solid solution strengthening, precipitation hardening, and oxide dispersion strengthening. In this study, six different Ni-Cr-Y-Ti-Al feedstocks produced through gas atomization reaction synthesis (GARS) were consolidated through laser powder bed fusion. These six batches varied in Y-Ti content, oxygen content, and ratio of gas to metal during atomization. Transmission electron microscopy (TEM) conducted on both powder particles and consolidated parts were performed to determine effects of chemistry on nickel alloys produced via melting. The influence of yttrium, titanium, and oxygen content on the production of oxide dispersion strengthened nickel vs an alloy containing a cell structure is discussed. |
