Mechanism and kinetics of reaction diffusion in steels under the conditions of simultaneous external and internal oxidation

详细

Thermodynamic prerequisites for the formation of internal oxidation zones in multicomponent alloys (metal-solvent + alloying element + insertion element (oxygen, nitrogen, carbon)) are presented. The kinetics of changing the component concentrations upon the formation of one- and two-phase oxide layers is shown. The boundary conditions for the formation of the internal oxidation zones are determined.
