Comparison of results from Raman and EDS/SEM analysis of ferritic Cr-Mo-V steel T91 (UNS: K90901) cross-sectioned after oxidation at 1200 C for 2 hrs in air

Raman images acquired from a cross-sectioned segment of ferritic Cr-Mo-V steel T91 (UNS: K90901) after oxidation in air at 1200 C for 2 h. Raman data was collected using a WITec alpha 300R micro-imaging Raman microscope. Results provide evidence to the presence of Fe(3-x)CrxO4.
