In the current study, the effects of extrusion temperatures on the extrudability, microstructure, recrystallization behavior and mechanical properties of the Mg–3.0Zn–0.2Ca–0.5Y alloy have been systematically investigated. The results show that the magnesium alloy bars with excellent mechanical prop...
