Improving Formability of Mg–Ca–Zr Sheet Alloy by Microalloying of Zn

“…The improved stretch formability and ductility of the Mg-0.5Ca-0.1Zr-0.1Zn sheet are attributed to the enhancement of grain boundary cohesion and the weakening of sheet texture due to the Zn addition. 3) The lower proof strength of the annealed Mg-0.5Ca-0.1Zr-0.1Zn alloy sheet as compared with the AZ31 counterpart can be significantly improved by artificial ageing treatments. The improvements in strength by post-forming ageing are associated with a dense distribution of nanoscale plate-like precipitates on the basal plane of the Mg matrix.…”

“…[1,2] However, the current usage of commercial Mg sheet alloys such as AZ31 (Mg-3Al-1Zn-0.3Mn, wt%) is very limited due to their poor formability at near room temperatures, which is usually related to the strong basal texture developed during thermomechanical processing. [3] Alloying additions have been shown to be an effective way to weaken the basal texture of Mg sheet. [4] For example, the additions of a small amount of rare earth (RE) or Ca to Mg-Zn alloys have been reported to weaken the sheet texture and, thus, improve the formability.…”
