Available in PDF, EPUB and Kindle. Book excerpt: "The thermodynamic properties of iron-carbon-lead alloys are of interest for a variety of reasons related to steel production and recycling. Experimental procedures are described for a research program measuring the activity of lead in liquid iron and iron-carbon alloys. The solubility of lead in iron/iron-carbon alloys has been measured by equilibrating lead vapors with the iron/iron-carbon samples, in the temperature range of 1250° C -1600° C. The carbon composition of the iron-carbon alloys was in the range of 0 to 5.4 wt %. The solubility of lead increases with an increase in the temperature and decreases with an increase in the carbon content of the iron-carbon alloy. The measured solubility data for lead in molten iron/iron-carbon alloys were used to calculate the activity coefficient for lead using the Bale-Pelton unified interaction formalism as a function of alloy composition and temperature. The expression for In [gamma]°[subscript Pb-C] in the liquid region of the iron-carbon phase diagram as a function of temperature and carbon content is given by: [FORMULA] where [gamma]°[subscript Pb-C] is the Henrian activity coefficient of lead with respect to liquid lead as the reference state, T is the temperature in Kelvin and X[subscript c] is the mole fraction of carbon"--Abstract, leaf iii
