Abstract
A liquid Fe-C-Ti system was studied by establishing an iso-titanium-activity state for ternary samples at 1600 °C through the medium of a bath of liquid silver which permits diffusion of titanium only. From the two iso-titanium-activity lines obtained, the self-interaction coefficients of titanium and interaction coefficients of carbon on titanium in liquid iron were estimated:ε Ti Ti = 4.67, ρTi Ti = 0.32, εTi C = −11.94, ρTi C = −4.52, ρTi Ti,C = −9.96 An experimental study has been made of the distribution of titanium between liquid silver and liquid iron at 1600 °C. By the use of the interaction coefficients of titanium and rTi o in liquid iron, the thermodynamic parameters of titanium in liquid silver were determined asr Ti o Ag = 2.44 X 10−3, (εTi Ti Ag = −6.17, (ρTi Ti)Ag = −16.3
