The purpose of this study is to reveal the effect of solute elements on microstructural evolution of high purity aluminium during severe plastic deformation. Firstly, high purity binary aluminium alloy was prepared, and then ultra-fine grained high purity binary aluminium alloy was fabricated using severe plastic deformation. Microstructural observations, high resolution electrical resistivity measurements, tensile tests were performed, which provides the information of lattice defects during severe plastic deformation.

本研究旨在揭示溶质元素对高纯铝在大塑性变形过程中组织演变的影响。首先制备了高纯二元铝合金，然后通过大塑性变形制备了超细晶高纯二元铝合金。进行了显微组织观察、高分辨率电阻率测量、拉伸试验，提供了严重塑性变形过程中晶格缺陷的信息。
