Thermodynamics of metallurgical processes in manganese-based melts

The theory of quasi-regular solutions may be used to convert the molar interaction parameters from one type of alloy to another. Hence, the thermodynamic characteristics of manganese alloys may be estimated from data for iron alloys. On that basis, the molar and mass interaction parameters of elemen...

Description
Summary:The theory of quasi-regular solutions may be used to convert the molar interaction parameters from one type of alloy to another. Hence, the thermodynamic characteristics of manganese alloys may be estimated from data for iron alloys. On that basis, the molar and mass interaction parameters of elements in manganese melts may be calculated, as well as the heats of solution and activity coefficients of the elements and the change in Gibbs energy on reduction, desulfurization, denitrogenation, and reductive dephosphorization of manganese and also in the refining of manganese by chlorides and fluorides. The possibility of removing impurities from manganese is assessed.
