Aghaeian, S. (author), Brouwer, J.C. (author), Sloof, W.G. (author), Mol, J.M.C. (author), Bottger, A.J. (author)Since the oxidation reactions in the process of steel production occur in harsh conditions (i.e., high temperatures and gas atmospheres), it is practically impossible to observe in situ the compositional changes in the steel and the formed oxide scale. Hence, a coupled thermodynamic-kinetic numerical model is developed that predicts the...journal article 2023
