Abstract :
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.
