An integrated approach involving liquid-solid diffusion couples (LSDCs) and forward simulations is employed to reliably obtain diffusion coefficients of several important alloying elements such as Al, Zn, Sn, Ca, and Y in Mg. The Ca diffusion in Mg is the first experimental measurement. The experimental data are essential input to reliable diffusion (mobility) databases for simulation of kinetic processes in Mg alloys. Slices of LSDCs are annealed at lower temperatures to induce precipitation at various supersaturations formed in the LSDCs to effectively study the precipitation as a function of alloy composition. Such results can be used to aid alloy design and to validate model predictions.
