Numerical models for predicting the nonisothermal oxidation kinetics of metals

numerical models;  non-isothermal oxidation;  High temperature oxidation

Although the Morkworth model can predict the nonisothermal oxidation kinetic process of metals in industrial production, the mathematical processing is very complicated when the temperature-time relationship is nonlinear. A numerical model for predicting non-isothermal oxidation kinetics by isothermal oxidation kinetic parameters is proposed, which has clear physical significance and is easier to deal with the problem of nonlinear oxidation with temperature-time relationship than the Markworth model. The experimental results show that the prediction results of this numerical model are consistent with the experimental results.
