This project aims to explore, starting with first principles, the effect of changes in chemical composition via alloying additions on the energetics of slip and deformation twinning. Through this computational and experimental program, we identified the physical processes that link solutes to defect dynamics and to twin nuclei and lamellae expansion. The scientific knowledge served as a basis to create a computational method to navigate the solute parameter space for 3D twin mesh architectures. The efficacy of 3D twin meshes for achieving high strength and toughness in otherwise weak and brittle Mg was demonstrated in a number of binary systems.
