説明

Experiments on the solid-liquid equilibrium relationship in Fe-Si-O alloys were carried out using the zone melting technique.<BR>The deoxidation constant with silicon in liquid iron was log KSi (l) =-5.18 ([%Si (l)] <0.64) at the solid-liquid equilibrium temperature, which is in good agreement with the values given in the literature.<BR>The silicon-oxygen equilibrium relationship in δ-iron at the solid-liquid equilibrium temperature is represented by the following equations:<BR>log aSi (s) ·aO (s) 2=-7.19 ([%Si (s)] ≤0.5)<BR>log fSiSi (s) =0.086 [%Si (s)]<BR>log fOSi (s) =-15.9 [%O (s)]<BR>log fSiO (s) =-9.05 [%Si (s)] +30 [%Si (s)] 2 ([%Si (s)] ≤0.1)<BR>log fOO (s) ≈0
