Abstract The influence of Sb on the C solubility in liquid Fe was determined under 1300,1400 and 1500℃. The C solubility decreases with the increase of Sb content. The temperaturedependences of the first order interaction coefficients in C-saturated liquid Fe are:*e_c~(sb)=11. 309/T+0.0025*e_(sb)~c=128.023/T-0.0219The temperature dependences of interaction coefficients between Sb and C in dilute liquid Fe are:e_c~(sb)=14.204/T+0.025e_(sb)~c=120.541/T+0.227ε_c~(sb)=ε_(sb)~c=6026. 75/T+11.958The interaction coefficients at 1600℃ are *e_(c)~(sb)=0.0085, e_(c)~(sb)=0.033, e_(sb)~c=0.295, ε_c~(sb)=ε_(sb)~c=15.36.The first order interaction coefficients vary slightly with temperature.
