研究了Mg-8%Li-1%Al合金在403 K等通道转角挤压（ECAP）过程中的组织演变和室温拉伸性能。结果表明，通过一次又一次的强化，可以提高强度。在第一道次ECAP后，断裂伸长率急剧下降，但在随后的ECAP过程中可以逐道次提高。微观结构分析对这些现象给出了解释。
The microstructural evolution and room temperature tensile properties of Mg–8%Li–1%Al alloy processed by equal channel angular pressing (ECAP) at 403 K were investigated. It was found that the strength could be improved pass by pass. The elongation-to-failure decreased dramatically after the first ECAP pass, but could be improved pass by pass during the subsequent ECAP procedure. The microstructure analysis gave the explanations for these phenomena.
