Thermodynamic analysis of the oxidation period of making a nickel-based multicomponent superalloy

The oxygen activity is studied by oxygen sensors during the oxidation period in experimental heat of a superalloy in a 5-t electric arc furnace. The results of chemical analysis of metal and slag samples are used to calculate the activities of the metallic and oxide solution components using the energy parameters of the models of a pseudosubregular solution for the melt and a pseudoregular ionic solution for the slag, which were determined and...
