Interaction Parameters in Metallic Solutions Estimated from Liquid Structure and the Heat of Solution at Infinite Dilution

摘要

The interaction parameters have been calculated for 120 ferrous alloy solutions using the pseudo-potential formalism coupled with the free energy of the hard sphere model. An agreement between calculation and experimental data appears to be reasonable with the 83% reliability in predicting the correct sign. The interaction parameters of oxygen in silicon melt were also estimated for 10 minor elements. The results, obtained only from some fundamental physical constants as inputs, are found to be useful in making qualitative discussion about the solubility of the desired element in metallic solutions.
