| Abstract Scope |
Mg alloys containing Ca and Zn exhibit weakened texture due to deformation twin suppression and encouragement of dislocation slip to accommodate c-axis deformation. In this study, the microstructure (e.g. grain size, morphology, and orientation) and crystallographic texture evolution of two binary and one ternary Mg alloy(s): Mg-Ca, Mg-Zn, and Mg-Ca-Zn during static recrystallization were systematically quantified using in situ heating coupled with SEM and EBSD. It was found that the Ca-containing alloys exhibit limited deformation twinning, which results in grain boundaries and triple junctions as the preferred nucleation sites during recrystallization. Grains that have recrystallized from these sites exhibit more random orientations, which results in a weaker texture after recrystallization. Contrarily, Mg-Zn exhibited prevalent deformation twinning, which served as nucleation sites for recrystallized grains with similar orientations as the parent grain, resulting in a stronger texture after recrystallization. |
