Validation of the flux partitioning of species model was illustrated. Various combinations of inequality expression for the fluxes of species A and B in two successively grown hypothetical intermetallic phases in the interdiffusion zone were considered within the constraints of this concept. Furthermore, ratio of intrinsic diffusivities of the species A and B in those two phases was correlated in four different cases. Moreover, complete and or partial validation or invalidation of this model with respect to both the species, was proven theoretically and also discussed with the Co-Si system as an example.
