OXYGEN SOLUBILITY IN VANADIUM-CONTAINING Fe – Co – Cr MELTS

Abstract

Thermodynamic analysis of the effect of vanadium on the solu­bility of oxygen in Fe – Co – Cr melts has been carried out. Vanadium in Fe – Co – Cr melts at low contents increases oxygen concentration, which is determined by the chromium content. With a higher content of vanadium after changing the mechanism of the interaction process of chromium and vanadium with oxygen, when vanadium already de­termines the solubility of oxygen in the melt, the oxygen concentration initially decreases, and then, after passing through the minimum point, increases.
