    The back diffusion of a solidifying system under local equilibrium conditions can be simulated by using immaterial constraints as set to the (stoichiometric) conservation matrix of the alloy mixture. In a solidifying alloy, complete diffusion between the liquid and solid portions is often found for chemical components with small atoms which dissolve interstitially in the solid state. Carbon in steels is a classical example. The constrained Gibbs energy method appears to be a useful technique to incorporate the necessary restrictions for those components, which are not allowed to diffuse in the solidifying system, while the interstitial components can reach their partial equilibria.
