Abstract
Dependence of initial oxidation behavior on crystalline orientation of Haynes 230 at 900 °C was investigated by a novel method. Analysis of oxidation rate reveals that the oxide thicknesses are different for grains having different orientations. Orientation mapping was performed on oxidized specimen and grains having near {1 1 1} were easily indexed by electron backscattered diffraction. We determined that planes with deviation angle lower than 20° were all well indexed after oxidation. Results demonstrate that substrate orientation plays an important role on oxidation rate during the initial stage.
