The relation between two ductility mechanisms for Mg alloys revealed by high-throughput simulations

Understanding the deformation mechanisms of Mg has been a long-standing and significant problem for materials scientists. Currently, there are two widely acknowledged ductility-improving mechanisms, i.e., the dislocation nucleation mechanism and dislocation mobility mechanism. Since the two mechanisms were previously investigated using very different solute sets, hitherto there is no clear understanding of the relation between them. Based on the...
