Although rolled magnesium (Mg) alloys generally suffer from strong crystallographic textures and poor formability, adding Ca and Zn to magnesium sheet can result in a desirably weak recrystallization texture and improved formability. In this study, we explore the effect of Zn content on the static recrystallization of three 80% hot-compressed alloys, Mg-0.5Zn-0.1Ca wt.% (ZX050), Mg-1Zn-0.1Ca wt.% (ZX10) and Mg-3.2Zn-0.1Ca wt.% (ZX30), using far-field high-energy diffraction microscopy (ff-HEDM). Individual recrystallized grains are tracked and their 3D centroid, relative volume, and grain-averaged crystallographic orientation are measured during in-situ annealing. These measurements are used to compare the kinetics and texture evolution of recrystallized grains in ZX alloys as a function of Zn content. Fully recrystallized microstructures are observed for the ZX30 and the ZX10 alloys after annealing at 230ºC and 330ªC, respectively. In contrast, only a partially recrystallized microstructure for the ZX050 alloy is observed after >1 hour of annealing at 430ºC. The recrystallized grains also show slower growth rates for ZX050 as compared to ZX10 and ZX30. We also use the results to discuss the recrystallization grain textures, as well as the correlation between orientations and the nucleation and growth rates of recrystallized grains, both as a function of annealing time and Zn content.
