SEM/EDS analysis of surfaces 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

Backscattered (BSE) and secondary electron (SE) images of surfaces on ferritic Fe-Cr-Al-Mo alloy Kanthal APMT and Cr-Mo-V steel T91 (UNS: K90901) before and after oxidation at 1200 C for 2 h in steam or air. In addition, energy-dispersive x-ray spectroscopy (EDS) maps are included, noting the elemental distribution of Al, O, and Fe on surfaces of Kanthal APMT, along with generated reports used to compare of major composition regimes observed on surface of air- and steam-oxidized specimens with respect to the control. For T91, raw Electron Microscopy Society of America (EMSA) files for EDS spectra acquired from sites of interest depicted in the included images are also available.
