Laser powder bed fusion (LPBF) additive manufacturing (AM) is a promising route for the fabrication of oxide dispersion strengthened (ODS) steels. In this study, a 14YWT ferritic steel powder that was produced using a novel gas atomization reaction synthesis (GARS) method has been explored to fabricate intricately designed shapes and large prismatic blocks for feasibility and scalability. GARS powder bypasses the conventional mechanical alloying step typically required to produce ODS feedstock. Sub-sized tensile specimens have been harvested out of large blocks in various orientations from samples produced in varying powder chemistry, to analyze the effect of microstructural difference and powder chemistry on the mechanical properties of the samples.
