The microstructures and mechanical properties of Mg-2MM-2Sn-lAl-lZn (ETAZ2211) sheets fabricated under different conditions have been investigated. Two hot-rolling routes following extrusion have been carried out at 300 °C or 400 °C. One method is to roll the extruded strips parallel to the extrusion direction (ED); the other is to roll the extruded strips perpendicular to the extrusion direction (TD). The strength and the elongationto-fracture of specimens prepared by a combination of extrusion and rolling processes are increased dramatically when compared those of the simply rolled specimens. Especially, the TD alloy sheet rolled at 300 °C exhibits the best combination of strength and ductility, i.e. yield strength of 178.5 MPa, ultimate tensile strength of 239.1 MPa, uniform elongation of 24.4 % and elongation-to-fracture of 37.9 %. Observation of texture reveals that the intensity of (0002) texture is lower for the TD alloy sheets than that for the ED alloy sheets, indicating that the texture intensity is reduced by change of the rolling direction.
