Control of oxide inclusions in ODS FeCrAl steel by LPBF parameters Heat input is correlated with melt pool geometry and oxide inclusion content. Our researchers have modified laser powder bed melting parameters to produce an ODS-FeCrAl steel free of Y-Al-O oxide inclusions from a Fe-22Cr-5.1Al-0.5Ti-0.26Y and TiO\u2082powder mixture. This research provides a feasible method for in-situ removal of oxide inclusions from alloys during PBF processes. Oxide inclusions in alloys can degrade component fatigue life and can become preferential corrosion sites in seawater environments. When FeCrAl ODS steel is prepared via the PBF process, Y-Al-O oxide inclusions are generated due to the high affinity of Y and Al for O.
