Abstract
The existence and influence of mechanical stresses, appearing at a metal-oxide interface, on the rate and regularities of metal oxidation is analyzed. The source of these stresses involves, in particular, the difference in thermal-expansion coefficients and densities of metal and oxide. From this point of view, the oxidation parameters of Al, Ti, Zr, and Mg are calculated. It is shown that the suggested approach well describes qualitatively, and in some cases quantitatively, the numerous experimental data concerning oxide-layer structures, complex multistep parabolic oxidation, transition from protective to nonprotective oxidation, etc. Results of the calculations indicate that for cylindrical vessels internal pressure may result in significant intensification of the oxidation process.
