abstract = {The deformation mechanisms of Zn- and Al-alloyed Mg were
investigated using in-situ three-dimensional synchrotron
X-ray diffraction (3DXRD). The activation of basal and
prismatic slip was quantified in Mg-1Al (A1), Mg-1 Zn (Z1),
and Mg-1Al-1 Zn (ZA11) alloys in order to assess the
influence of solute alloying on slip system competition. The
results reveal that the combined addition of Zn and Al
facilitates prismatic slip activation by reducing its
critical resolved shear stress (CRSS), and leads to the
lowest RSS$_{prism}$/RSS$_{basal}$ ratio of 5.44, compared
to 6.25 in A1 and 6.23 in Z1. This indicates a more balanced
activation of basal and non-basal slip systems. Grain
rotation analysis further suggests that ZA11 accommodates
deformation more effectively through non-basal slip,
reducing stress localization. These findings provide direct
insights into how solute interactions influence slip system
activity and offer guidelines for optimizing Mg alloys for
improved ductility and mechanical performance.},
