Abstract

A thermodynamic analysis of the oxygen solutions in the titanium-containing Ni–Cr melts at 1873 K has been performed. The oxygen solubility in the Ni–Cr melts is shown to be higher than that in pure nickel. The higher the chromium content, the higher the oxygen solubility. Low titanium contents weakly affect the oxygen concentration in a melt, which is determined by the chromium content. At titanium contents of above 0.020–0.035%, titanium determines the oxygen solubility in a melt depending on the alloy composition. The titanium contents at the minima in oxygen solubility curves and the oxygen concentrations corresponding to the titanium contents have been determined.
