Abstract :
In glasses and crystals the deviation of self-diffusion process for single component from the Arrhenius law is often observed. Various experimental results show that the diffusion coefficient can depends not only on the concentration of this single component, but also on concentration of other components. The article presents the mathematical model describing one possible mechanism of occurrence of such dependence. The iterative procedure for solving closed system of equations model of nonlinear multicomponent diffusion is constructed.
