To have a better understand on the change of microstructure via
kinetics, the diffusion behavior of Mg alloys is of special interest to
researchers. Meanwhile, diffusion coefficients of Mg based alloys can
explain and represent their diffusion behavior well. The evolution of
experimental and calculated methods for detecting and extracting
diffusion coefficients was discussed briefly. The reasonable diffusion
data, especially self-diffusion coefficients, impurity diffusion
coefficients and inter-diffusion coefficients of Mg alloys, were
reviewed in detail serving to design the Mg alloys with higher accuracy.
Then the practical applications of diffusion coefficients of Mg alloys
were summarized, including diffusional mobility establishing,
precipitation simulation and mechanical properties prediction.
