Abstract
Foil extension experiments have been used to determine the stresses arising in oxide scales growing on iron and rimming steel in CO2 during the protective and breakaway stages of oxidation. There is no definite association of either tensile or compressive stresses with protective oxidation, and scale stresses cannot be invoked to explain the mode of protective growth or the nucleation of breakaway oxide. Breakaway oxidation generates compressive stresses in the scale which cause tensile deformation of thin foils. Metallographic observations suggest that significant factors in the transition from protective to breakaway oxidation are prior formation of a duplex protective scale and carburization of the underlying metal.
