The equilibrium distribution coefficients ko. for some solutes in Fe-C-base ternary alloys have been ex perimentally investigated. The mechanisms of these solute distributions between solid and liquid phases have also been discussed on the basis of thermodynamics.
The experimental results show that ko of Ni increases and ko of V decreases with increasing carbon content, and the distributions of C in Fe-C-Ni and Fe-C-V alloys differ little from those in Fe-C binary alloys. The effect of carbon on kos of Ni and V can be thermodynamically explained by using the interaction parameter, the activity coefficient and so on.
