Because of the low symmetry hexagonal close packed atomic structure of Mg there are a limited number of deformation mechanisms to accommodate deformation along the crystallographic c-axis. Only one dislocation slip based mechanism can accommodate deformation along the c-axis. Therefore, deformation twinning plays a dominant role in the accommodation of deformation along the c-axis. ...

High speed imaging is combined with high strain rate loading to probe the evolution of strain localization leading up to failure in Mg alloys. From this study pathways for deformation are identified which lead to undesired shear band formation and crack formation. Show below is a comparison of the strain localization that occurs at...
