文章亮点

(1) 斜坡挤压，其通过额外引入倾斜界面，产生更多的不对称变形和更强的累积应变。

(2) 斜坡挤压过程中法向应变的增加，致使晶粒细化，织构增强及组织均匀性的提高。

(3) 经斜坡挤压后的板材具有优异的强塑性表现，归因于晶粒细化与织构强化的综合作用。

中文摘要

本文设计及采用了一种新型的挤压方法——斜坡挤压（SE），成功制备了AZ31镁合金板材。将其与采用常规挤压方法（CE）制备的AZ31板材，从组织、织构和室温力学性能等三方面进行综合比较。最终结果表明：由于在挤压前通过电火花线切割的方式成功在坯料中引入了倾斜界面，进而在挤压过程中会产生更多的不对称变形和沿板面方向更强的累积应变，故而经过斜坡挤压后的板材，其晶粒尺寸得到了显著的细化（平均晶粒尺寸从9.1 μm 下降至 7.7 和 5.6 μm），基面织构强度获得了明显提升（织构强度从11.5 mrd 增加至 19.8 mrd 和 25.4 mrd）。因此，经过斜坡挤压后的AZ31镁合金板材，其屈服强度（YS）和极限抗拉强度（UTS）均高对应常规挤压方法（CE）制备的AZ31板材，这主要是晶粒细化和织构强化的协同作用所导致。

Abstract

Abstract

A novel extrusion approach, entitled slope extrusion (SE), was employed to manufacture AZ31 (Mg–3Al–1Zn, wt%) alloy sheets. The microstructures, textures, and mechanical properties were investigated, compared with those of the AZ31 sheet fabricated by conventional extrusion (CE). Through the combination of finite element simulation and actual experiment, the ultimate results indicated that significant grain refinement (from 9.1 to 7.7 and 5.6 μm) and strong basal texture (from 12.6 to 17.6 and 19.5 mrd) were achieved by the SE process. The essence was associated with the additional introduced inclined interface in the process of SE, which could bring about more asymmetric deformation and stronger accumulated strain along the ND when compared with the process of CE. As a consequence, the SE sheets exhibited a higher yield strength (YS) and ultimate tensile strength (UTS) than the counterparts of the CE sheet, which was mainly assigned to the synergistic effects from grain refining and texture strengthening.
