The tensile properties at room temperature ∼573 K of Mg-9Al-1Zn processed by normal extrusion were compared with those processed by equal channel angular (ECA) extrusion. The strength at room temperature was strongly affected by the grain size. However, the effect of the grain size rapidly decreased with testing temperature. At room temperature, the normal extruded alloy showed the stronger grain size dependence of 0.2% proof stress than the ECA extruded alloy because of the microscopic orientation effect. Also, the grain size dependence was reduced when grain boundaries were in a non-equilibrium state.
