| Abstract Scope |
The application of external magnetic field during annealing has been found promising in tailoring the properties of non-ferromagnetic materials, especially enhancing atomic mobility and diffusion; however, a fundamental understanding of the dependence of interdiffusion coefficients on applied magnetic field is lacking. This study investigates the influence of magnetic field on solid-state diffusion in an Al/Mg/Zn diffusion couple. The couple was annealed at 350C under the application of a 0, 3, and 6T magnetic field for 15h. The compositional profile, constituent phases and diffusion thickness across the Al/Mg and Al/Zn interfaces were studied using SEM/EDS. The interdiffusion coefficient across the composition and that of the different ensuing phases were calculated leveraging Wagner approach. These results will be used to elucidate the mechanisms that give rise to increased strength and precipitation kinetics observed for Mg- and Zn-containing Al alloys arising from the application of an external magnetic field during annealing. |
