SEM/EDS analysis cross-sectioned segments of ferritic Fe-Cr-Al-Mo alloy Kanthal APMT and Cr-Mo-V steel T91 (UNS: K90901) after oxidation at 1200 C for 2 h

Images of cross-sectioned segments extracted from ferritic Fe-Cr-Al-Mo alloy Kanthal APMT and Cr-Mo-V steel T91 (UNS: K90901) after oxidation at 1200 C for 2 h in steam and air. Backscattered electron images (BSE) included for all specimens were captured using a JEOL 7600F scanning electron microscope (SEM). Optical micrograph is included of steam-oxidized T91 acquired with a Nikon MM-40 optical microscope. Each microscope image is accompanied by an energy-dispersive x-ray spectroscopy (EDS) elemental map depicting the distribution of elements Al, O, and Fe for APMT and Cr, Fe, and O for T91.
