Solubility of Oxides in Liquid Alloys Containing Titanium and Zirconium

Abstract

The oxygen solubility curves for Fe–Ti–O, Co–Ti–O, Ni–Ti–O, Fe–Zr–O . Co–Zr–O and Ni–Zr–O alloys saturated with oxides of titanium and zirconium were calculated. The experimental data of Fe–Ti–O and Fe–Zr–O systems from the literature correlate reasonably well with the calculated curves from the model by Wagner and the empirical correlation of Chiang and Chang over the temperature range of 1823 K to 2073 K . The Gibbs energies of oxygen in liquid titanium, ΔG_O(Ti)^° and zirconium, ΔG_O(Zr)^° were also estimated.
