Twin roll cast and hot rolled Mg-6.2. wt%Zn alloys microalloyed with Zr, Ca, and Ag show tensile yield strength exceeding 300. MPa in the T6 (peak-aged) condition with reasonable formability in the T4 condition. The addition of Zr and Ca plays a critical role in the development of weak textured recrystallized microstructure in Mg-6.2. wt%Zn alloys so Mg-6.2Zn-0.5Zr-0.2Ca (wt%) alloy shows equivalent mechanical properties with Mg-6.2Zn-0.5Zr-0.2Ca-0.4Ag (wt%) alloy even without expensive Ag. © 2014 Elsevier B.V.
