Abstract

Carbon solubility in Mn-Fe melts (xMn=0.083 − 0.706, xFe = 0.034 − 0.715) was measured experimentally at various temperatures. By thermodynamic derivation and calculation, the relationship between activity coefficient of carbon in infinite dilute solution of manganese in Mn-C system and temperature was obtained. Using Gibbs-Duhem relationship, the experimental results of this study, and experimental data obtained by strict thermodynamic derivation and calculation in references, the relationships between other thermodynamic properties (εCC, εCCC, εCFe, εCCFe, and εcFeFe) in Mn-Fe-C system and temperature were obtained.
