Thermodynamics of oxygen solutions in the Fe-Co-Cr melts containing silicon, titanium, and aluminum

摘要

Effect of Si, Ti, and Al on the oxygen solubility in the Fe-Co-Cr melts at 1873 K was thermodynamically analyzed. At low Si, Ti, and Al contents, the oxygen concentration increases very slightly. At the higher their contents, when the mechanism of interaction of Si, Ti and Al with oxygen is changed, just these elements determine the oxygen solubility in melt and the oxygen concentration decreases significantly.
