• The activity coefficient of sillicon in the molten Fe-C-B-Si alloy was determined by conducting the following measurements: 1) Equilibrium contents of boron in the Fe-B-Si-N alloys saturated with solid BN under Ar+N<SUB>2</SUB> gas mixture at 1723 K, 2) Solubility of carbon in the molten Fe-C-B-Si alloy at 1573 and 1723 K, and 3) Equilibrium distribution of silicon between the molten Fe-C-B-Si alloy and molten silver at 1723 K. By using the interstitial solution model, the activity coefficient and the interaction parameters of silicon in the Fe-C-B-Si alloy were determined to be:<I>θ</I><SUB>B</SUB><SUP>Si</SUP> = 7.54 (<I>y</I><SUB>Si</SUB><0.15, 1723K), ln<I>ψ</I><SUB>Si</SUB><SUP>O</SUP> = -8.7,     <I>θ</I><SUB>Si</SUB><SUP>Si</SUP> = 18.4 (<I>y</I><SUB>Si</SUB><0.2, 1723K), <I>θ</I><SUB>C</SUB><SUP>Si</SUP>=<SUB><I>T</I></SUB><SUP><U>297000</U></SUP> - 2.63 (<I>y</I><SUB>Si</SUB><0.4, 1573-1873K)
