Abstract

The solubilities of nitrogen in liquid Fe-Ti, Fe-Al and Fe-O alloys were measured at 1600-1700°C by the same method as that in report I (Tetsu-to-Hagané, 46 (1960), p. 748).
The results obtained were as follows:
(1) The solubility of nitrogen in the liquid iron was increased with increase of titanium and oxygen contents.
But the solubility was decreased with increase of aluminum content.
(2) The effect of alloying elements on the activity coefficient of nitrogen in liquid iron was summarized as follows:
