Solubility of Nitrogen in Liquid Iron and Effect of Carbon, Silicon and Manganese on the Solubility
熔鉄の窒素の溶解度について-I
Solubility of nitrogen in liquid iron and iron alloys-I

説明

The solubilities of nitrogen in liquid iron and liquid Fe-C, Fe-Si and Fe-Mn alloys were measured at 1500-1700°C. The results on liquid iron confirmed that Sievert's law was followed in the range 95 to 760mmHg pressure. The results obtained were as follows: (1) The solubility of nitrogen in liquid pure iron was expressed as follows: %N=1·2×10^-5×T+0·0171 (2) The effect of carbon, silicon and manganese on the activity coefficient of nitrogen in liquid iron alloys was calculated by the following relation: logfN=logC⁰_N-logC_N (3) The effect of alloying elements on the activity coefficient of nitrogen in liquid iron was summarized as below: logf ^(C) _N=+0·135·%C C<4% logf ^(Si) _N=+0·048·%Si Si<4% logf ^(Mn) _N=-0·020%·%Mn Mn<4% 1500-1700°C
