Incorporation of vacancy generation/annihilation into reactive diffusionnconcept – Prediction of possible Kirkendall porosity
Original language description
The reactive diffusion concept represents an approved handy tool for simulation of diffusive phase transformationsnin binary systems. The local value of the site fraction of a particular component, obtained bynsolution of diffusion equation, determines its affiliation to a phase or to an interface, to which the respectivenchemical potentials and kinetic coefficients, used in diffusion equation, can be assigned. The reactivendiffusion concept is now generalized to account for intensity of non-ideal sources and sinks for vacancies,nwhich allows the treatment of the Kirkendall effect and an according prediction of formation of pores. Thennew concept is demonstrated on an instructive example showing the kinetics of phase transformation,nshift of the Kirkendall plane and evolution of site fraction profiles. Local supersaturation by vacanciesnindicates the possible formation of pores.
