Some remarks about the kinetics of the competitive growth in multicomponent systems

Kinetics of the competitive growth of k-phases during the diffusive decomposition is commented on multicomponent solid solutions. It analyzes how the common component among phases controls their survival. Equations that determine the kinetic behavior of a multicomponent system with k-phases, in the last stages of the diffusive decomposition, are discussed taking into account the common component (or controller component). The parameters that determine which of these phases will survive during the competitive process are deduced. •The common component controls the survival of the phases in a n-component system.•A parameter to measure the “thermodynamic disadvantages” of each phase was obtained.•The phase that has the smallest value of this parameter θs will survive.•The parameter θs only depends of the structure and composition of each phase.
