Effect of Li on the deformation mechanisms of nanocrystalline hexagonal close packed magnesium

Addition of solutes such as lithium enhances ductility of hexagonal-close-packed (hcp) magnesium (Mg). However, the atomistic underpinning of Li addition on individual deformation mechanisms remain unclear and is the focus of the present work. We compared the deformation mechanisms in nanocrystalline (NC) and single crystal simulation systems...
