General Laws and Influence of Various Factors on the Internal Oxidation Mechanism and Kinetics in Alloyed Steels

  • A. B. KorostelevEmail author


The general laws (continuity equation) and the influence of boundary factors on diffusion equations for the internal oxidation zones in multicomponent alloys are presented. The diffusion equations in a continuous oxide layer and the internal oxidation zone are given. The combined solution of these equations provides sufficiently full information about the kinetic regularities of the phase formation in the reaction diffusion zones. This solution also allows one to construct a concentration distribution of the components in the internal oxidation zone and an external oxide layer.
