Abstract Scope Thermally and mechanically stable nano oxide dispersoid spread throughout the grain boundaries in a Fe-Cr Oxide Dispersion Strengthened (ODS) ferritic steel offers excellent creep, fatigue, and improved radiation resistance at high temperatures. Recent progress in Gas Atomization Reaction Synthesis (GARS) technique has shown that rapid solidification of a Cr-rich matrix resulted in the formation of stable Y-containing intermetallic Y2Fe17 on the interior of the powder, and a stable Cr-rich oxide surface. This research focuses on exploring the feasibility of 14YWT composition produced by GARS method in the domain of laser powder bed fusion additive manufacturing method under different atmospheric conditions (Argon and Argon + different oxygen % by weight) and extensively evaluate and analyze the microstructure properties of samples printed under different process parameter and atmospheric conditions. This research also aims to create a process map that will identify parameters that yield ≥ 95% relative density and process stability/repeatability.
