Effects of Zn on microstructure, mechanical properties and corrosion behavior of Mg-Zn alloys

► The microstructure of Mg-Zn alloy consists of α-Mg matrix and MgZn intermetallic. ► The addition of Zn to Mg up to 5 wt.% has beneficial effect. ► A network structure of MgZn intermetallic phase exhibits deteriorated effect.
