A high-throughput experimental approach is presented to extract theanisotropic interdiffusion coefficient by combining information over thecomposition profiles obtained by the electron probe microanalysis (EPMA) andthe grain orientation spectrum by the electron backscatter diffraction (EBSD)on polycrystalline diffusion couples. Following the forward-simulation scheme,the interdiffusion coefficients in grains with diverse orientation are obtainedand subsequently used to determine the anisotropic interdiffusion coefficientsperpendicular (D_\perp (x)) and parallel (D_\parallel (x)) to the c axis of thehcp Mg lattice in a Mg-Al alloy as a function of the Al solute content at 673 Kand 723 K, respectively. It was found that the interdiffusion coefficientsgenerally increased with the Al content and the rotation angle with respect tothe c axis with a valley point around {\theta} approx 30 {\deg} at 723 K. Andit was noticed that diffusion along the basal plane was always faster thanalong the c axis. A comprehensive explicit expression of the interdiffusioncoefficients was provided as a function of Al content, grain orientation andtemperature. The anisotropic impurity diffusion coefficients of Al in hcp Mgderived by the extrapolation of the results in this paper are in good agreementwith first principles calculations in the literature.
