Abstract
Magnesium alloy sheets were processed by conventional extrusion (CE) and differential speed extrusion (DSE). The velocity evolutions of DSE sheets at near-surface and mid-layer region are different due to the extra asymmetric shear deformation. This simple shear enforces the near-surface microstructure to exhibit more dynamically recrystallized grains having the c-axis tilted about ±12° toward the extrusion direction. Grain refinement and tilted weak basal texture obtained by DSE process dramatically enhance the room temperature strength and plasticity of the extruded Mg alloy sheets.
