Excellent ductility and stretch formability of Mg-2Zn-1Mn-0.5Ca-0.1Gd sheet at room temperature

•The present Mg alloy sheet possesses the high ductility (~25%) and super-high IE values(~7.53 mm).•The ZMX21 alloy sheet exhibits a high n value and lower r value.•Weakened ND-splitting texture and high SF are the key role on influencing stretch formability The microstructure, mechanical properties...
