Multicomponent diffusion and the time evolution of component concentrations are analyzed mathematically and equations presented which describe the behavior both with and without the need for the traditional interdiffusion coefficients. Both approaches were simulated and predicted results for time-evolved concentrations from a known starting state were compared to the results from a prior physical experiment involving the diffusion of three metals. The results for both approaches generally agree with the experimental results. The new approach bypassing the need for calculating the interdiffusion coefficients appears viable.
