中文摘要	Mg-6.6%Y-2.3% Zn (WZ62, mass fraction) magnesium alloys were fabricated by equal-channel-angular-extrusion (ECAE), and ECAE followed by forging processing, respectively. The "necklace" structure that is composed of fine recrystallized and coarse initial grains was found. The process of dynamic recrystallization (DRX) is associated with the strain localization. With increasing ECAE passes, the tensile test results reveal that both the strength and elongation are enhanced. A typical non-basal texture component in the (0002) pole figures with tilted peaks at about 45 was observed. After ECAE followed by forging processing, the strength increases greatly with sacrificed ductility. That is attributed to the change in the texture: the majority of basal planes is rotated to be normal to the normal direction. The non-basal texture induced by ECAE is modified by the secondary forging processing.
