On the Relation Between Oxide Ridge Evolution and Alloy Surface Grain Boundary Disorientation in Fe–22 wt % Cr Alloys

Oxide ridges formed during the transient stage oxidation of the scale evolution in iron alloys containing 22 wt % Cr that were held at in dry air. The surface oxidation process was imaged in situ through a confocal scanning laser microscope, and the results were correlated with postexperiment characterization through scanning electron microscopy and the DualBeam system (focus ion beam and electron beam) analysis combined with three-dimensional...
