Additive manufacturing introduces high microsegregation into the interdendritic regions, which possess high driving force for secondary phase nucleation and growth during post-processing heat treatments. The goal of this research is to model solid-state transformations in ternary systems representative of Ni-based superalloys in order to simulate the kinetics of competitive coarsening of some deleterious secondary phases embedded in highly enriched regions of the microstructure. Reversion kinetics in Inconel 625 using CALPHAD methods and a ternary analog using CALPHAD-coupled phase-field models will be discussed, with perspectives for the modeling effort and its application in experimental settings.
