In order to describe the effects of solute-interactions on the equilibrium distributions of solute elements between solid and liquid phases in iron base ternary system, Distribution Interaction Coefficient (DIC), kjiwas defined in this work. The coefficient kjiis shown as the ratio of the equilibrium distribution coefficient of solute i in Fe-i-j ternary system to that in Fe-i binary one and this is considered to be the parameter indicating the change of the equilibrium distribution coefficient of solute i with the addition of the alloying element j. The influences of solute-interaction on the equilibrium distributions of some solutes in Fe-C, Fe-N, Fe-H, Fe-P and Fe-S base ternary systems could be discussed by the use of the coefficient DIC.
