Abstract	Gas-atomized Fe–24Cr–8Al–0.5Y (wt.%) powder was used as a feedstock in a laser powder bed fusion process with nitrogen atmosphere. Formation of Al–Y–O-enriched nanoparticles with diameters of 10–100 nm implied in-situ precipitation of Al–Y–O-enriched nanoparticles within the ferritic matrix developing an oxide dispersion strengthened FeCrAl alloy without any mechanical alloying. Thermodynamics and kinetics of the internal oxidation during rapid solidification of laser powder bed fusion process are discussed.
