Low silicon carbon steel has been oxidised at varying temperatures in free flowing air using a thermomechanical simulator to control heating and cooling rates. The resultant oxide scales have been studies using Electron Backscatter Diffraction (EBSD) and the phases identified by the differences in the diffraction patterns. The crystallographic textures were calculated from the EBSD data. There is a correlation between the textures of the different phase layers within the scale, which depends on the formation mechanism of the individual phases.
