Abstract
Abstract—Thermodynamic analysis of the influence of aluminum on the oxygen solubility in the Fe–Co–Cr melts at 1873 K is performed. Aluminum in the Fe–Co–Cr melts is characterized by a high deoxidation ability. At a low aluminum content in these melts, it practically does not affect the oxygen content, which is determined by the chromium content. At a higher aluminum content after a change in the mechanism of interaction of chromium and aluminum with oxygen (when aluminum determines the oxygen solubility in a melt), the oxygen concentration decreases significantly, passes through a minimum, and increases.
