The first- and second-order interaction coefficients of V in Fe-C-V melts were accurately measured using the chemical equilibrium technique, by equilibrating CaO-MgO-Al 2 O 3 -VO x slags with Fe-C melts under controlled oxygen potential for 24 hours at 1873 K (1600 °C). The argon was employed as the protective gas and a purification device was used to control the oxygen potential in the atmosphere. The values of the interaction coefficients were determined as follows: $$ e_{\text{V}}^{\text{C}} = - 0.468,\quad r_{\text{V}}^{\text{C}} = 0.286,\quad r_{\text{V}}^{\text{V,C}} = - 0.213 $$ e V C = - 0.468 , r V C = 0.286 , r V V,C = - 0.213
