Thermodynamic Properties of Liquid Iron-Chromium-Oxygen Alloys

Abstract

<p>In this thesis the equilibrium between H2/H2O gas mixtures and iron-chromium melts was measured over a wide range of temperatures, 1470 - 1750°C. Specimens were levitated in selected H2/H2O gas mixtures, quenched and analyzed for oxygen. The gas composition fixed the oxygen potential in the system and allowed the thermodynamics of the oxygen solution reaction to be determined.</p> <p>Wagner interaction parameters were employed to describe the degree of chemical interaction between chromium and oxygen.</p>
