摘要

The activity coefficient of silicon 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_2 gas mixture at 1 723 K, 2) Solubility of carbon in the molten Fe-C-B-Si alloy at 1 573 and 1 723 K, and 3) Equilibrium distribution of silicon between the molten Fe-C-B-Si alloy and molten stiver at 1 723 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: θ_B~(Si) = 7.54 (y_(Si) < 0.15, 1 723 K), In ψ_(Si)~O = -8.7, θ_(Si)~(Si) = 18.4 (y_(Si) < 0.2, 1 723 K), θ_C~(Si) = 297 000/T -2.63 (y_(Si) < 0.4, 1 573-1 873 K)
