"Because of the interest in steelmaking and recycling, the thermodynamics of the Fe-C-Bi ternary system has been studied. The solubilities of bismuth in liquid iron/iron-carbon alloys and solid pure iron have been measured by equilibrating iron/iron-carbon alloys with bismuth vapor. The experiments were conducted in the temperature range from 1473 K to 1873 K and in the range of carbon contents from zero to carbon saturation. Bismuth behavior abides by Henry's law in liquid iron/iron-carbon alloys and solid pure iron. The solubility of bismuth in liquid iron/iron-carbon alloys increases with increasing temperature and decreasing carbon content. The solubility of bismuth in solid pure iron increases with increasing temperature. Thermodynamic modeling in the Fe-C-Bi ternary system was performed using the "unified interaction parameter formalism"....

The mutual solubility of bismuth and iron was discussed on the basis of the experimental data"--Abstract, page iii.
