Abstract:The thermodynamic properties of Fe-C-Sn liquid solution have beenstudied by using the solubility method in the temperrature range 1300-1500℃ andby using the iso-tin-activity with silver bath at 1550℃. The results are summarizedas follows: 1. The relation between the solubility of C and the content of Sn in liquid Feare: 1300℃ [%C]_(sat)=4.65-0.086[%Sn] 1400℃ [%C]_(sat)=4.86-0.106[%Sn] 1500℃ [%C]_(sat)=5.13-0.131[%Sn] 2. The solubility of C dependence on the content of Sn and the temperature isobtained as [%C]_(sat)=8.41-0.101[%Sn]-5904(1/T) 3. The temperature dependence of interaction coefficients between Sn and C inC saturated liquid Fe are ε_C~(Sn)=-(27170)/T+20.07; e_(Sn)~C=-(51.29)/T+0.041 4. The temperature dependence of interaction coeffients between Sn and C inliquid Fe are derived as e_C~(Sn)=-(194)/T+0.151; e_(Sn)~C=-(1810)/T+1.39 5. The first and second order interaction coefficients between Sn and C in liq-uid Fe at 1550℃ are determined as e_(Sn)~C=0.12; e_C~(Sn)=0.016; γ_(Sn)~C=0
