文章亮点

  • (1) 横向梯度挤压工艺制备多类型织构镁合金板材。
  • (2) 由于在挤出工艺中引入了沿板材横向的流速和沿挤出方向的流速差，基极沿板材横向从边缘到中心逐渐偏离法向方向。
  • (3) 由于横向梯度挤压板材在拉伸变形过程中，基面<a>滑移和拉伸孪晶容易被激活，板材具有优异的力学性能。
  • 采用横向梯度挤压（TGE）和传统挤压（CE）工艺制备Mg–3Al–1Zn（AZ31）镁合金板材，系统地研究了镁合金在挤压工艺中流变和动态再结晶行为，并对挤压AZ31镁合金板材的微观组织、织构和力学性能进行了分析。结果表明，由于在横向梯度挤压工艺中引入了沿板材横向额外流速和沿挤压方向流速差，板材具有细小晶粒的微观组织和多种类型的织构。板材横向从边缘到中心基极逐渐偏离法线方向，在板材中心区域达到最大倾角65°。此外，除了横向梯度挤压板材中心区域外，板材基极沿挤压方向向横向偏转40°–63°。与传统挤压板材相比，横向梯度挤压板材具有高的延展性和应变硬化指数（n值），低的屈服强度和Lankford值（r值）。由于横向梯度挤压板材在变形过程中基面<a>滑移和拉伸孪晶容易被激活，板材延伸率最高可达41%，屈服强度低至86.5 MPa。

    Understanding the superior mechanical properties of Mg–3Al–Zn alloy sheets: Role of multi-type unique textures

    + Author Affiliations
      Abstract
    • Mg–3Al–1Zn (AZ31) sheets were produced by transverse gradient extrusion (TGE) process. The flow behavior and dynamic recrystallization during extrusion were systematically analyzed. The microstructures, textures, and mechanical behavior of extruded AZ31 sheet were also analyzed and compared with conventional extruded (CE) sheet. The results showed that fine grain structure and multi-type unique textures were formed in TGE sheet because of the generation of extra flow velocity along transverse direction (TD) and flow velocity gradient along extrusion direction (ED) during extrusion. The basal poles gradually deviated away normal direction (ND) from edge to center of the TGE sheet along TD, and the largest inclination angle at center region reached around 65°. Furthermore, the basal poles inclined from ED to TD 40°–63°, except for the center region of TGE sheet. The TGE sheet presented higher ductility and strain hardening exponent (n-value), but lower yield strength and Lankford value (r-value) in comparison with the CE sheet. Both the basal <a> slip and tensile twins were easy to be activated during deformation, and the largest elongation of 41% and the lowest yield strength of 86.5 MPa were obtained for the ED-center sample in the TGE sheet.
