Activity Interaction Coefficients in Mn-Fe-C Melts
Mn-Fe-C熔体活度相互作用系数

The solubility of carbon in Mn-Fe-C melts was measured experimentally at different temperatures to obtain the activity interaction coefficients in Mn-Fe-C melts. A new method is used to treat experimental results. By thermodynamical derivation and calculation, some important relations between thermodynamical properties in Mn-Fe-C melts and temperature were obtained.
