Abstract
The effect of zirconium, cerium, and lanthanum up to about 1 wt pet on the solubility of oxygen in liquid iron in equilibrium with an oxide phase at 1680°C was measured. All three elements are strong deoxidizers of iron, and the oxygen solubility minimums were 10 ppm or less at 0.05 to 0.1 wt pet of the alloying element. The interaction coefficients were estimated from the results giving eo zr = −3, eo Ce = −3, and eo La = −5. When the concentration of the alloying element is expressed in wt pet, the effect of each of the three elements (Zr, Ce, and La) on the activity and solubility of oxygen in liquid iron is similar to that of aluminum.
