| Abstract: | High-temperature oxidation of several pure metals and their alloys gives rise to multilayered corrosion scales. This curious morphology has not been the subject of a specific investigation, and its interpretation remains widely open. This paper presents results on titanium foil oxidized in pure oxygen leading to this phenomenon. It analyzes the significant features of the stratification as a function of the main parameters of the reaction kinetics such as temperature, oxygen pressure, oxidation time, and initial thickness of the metallic foil. All the results, including those previously reported, show the importance and the consistency of the studied phenomenon as well as the incapability of providing an unequivocal intepretation at the present time. The analysis of the main results, such as the appearance of a macroscopic order, the existence of boundary limits, and the nonequilibrium state of the structure, shows that a consistent set of data exists to give a meaningful interpretation of multilayered corrosion scales in terms of a nonlinear, far-from-equilibrium organization.
