Abstract
"To understand the high-temperature thermodynamics of the iron-carbon-zinc system, the solubilities of zinc in iron/iron-carbon alloys have been measured by equilibrating zinc vapor with iron/iron-carbon samples, in the temperature range of 1473 K to 1873 K. The carbon composition was varied from 0 to 4.6 wt.%. The calculated zinc activities deviated positively from ideality. Zinc obeys Henrian behavior in liquid iron/iron-carbon alloys at PZn ≤ 1 atm. Generally, the solubility of zinc decreased with increasing temperature and carbon content. Based on experimental data, thermodynamic modeling of the iron-carbon-zinc system was performed in both liquid and solid solutions....
The equilibrium partition coefficient of zinc between the δ-ferrite and liquid regions of the iron-carbon phase diagram was calculated on the basis of the above two equations and estimated from experimental data for zinc between the austenite and liquid regions. Based on the present work, no significant segregation is expected during equilibrium solidification"--Abstract, page iii.
