项目摘要

Topic I: the fabrication of multi-pass caliber-rolled AZ31 alloyI gave a presentation about my results in the international academic conference of 'Seventh International Conference on Nanomaterials by Severe Plastic Deformation (NanoSPD7)' held in Sydney, Australia. The title was 'Microstructural Evolution and Mechanical Improvement of AZ31 Bulk Rod via Multi-Pass Caliber-Rolling Process'. The presentation received much attentions and I got various comments for the future work. It is of particular note that some researchers raised question about the extreme deterioration in mechanical properties between the caliber-rolling of 7th and 8th passes. I agree with their claims to thoroughly confirm the entire experiments under these conditions before submitting my work.Topic II: the cryogenic mechanical properties of multi-pass caliber-rolled AZ31 alloyI have also obtained the tensile data of caliber-rolled AZ31 rod deformed at cryogenic temperature (~150 K). The results, however, look insufficient to publish before carrying out a lot amount of additional experiments and analyses. This research project has been halted due to the reasons which had been submitted earlier, and thus the continue of these studies would be in veil for a while.

主题一：多道次轧制AZ 31合金的制备我在澳大利亚悉尼举行的“第七届国际纳米材料剧烈塑性变形会议（NanoSPD 7）”国际学术会议上发表了我的研究结果。题目是“通过多道次定径轧制工艺对AZ 31粗棒材的显微组织演变和机械性能改进”。这次演讲受到了广泛的关注，我得到了各种意见，为未来的工作。特别值得注意的是，一些研究人员提出了关于第7道次和第8道次径轧之间机械性能极度恶化的问题。我同意他们的说法，在提交我的工作之前，要彻底确认在这些条件下的整个实验。主题二：多道次径轧AZ 31合金的低温力学性能我还获得了径轧AZ 31棒材在低温（~150 K）下变形的拉伸数据。然而，在进行大量额外的实验和分析之前，这些结果看起来不足以发表。由于先前提出的原因，该研究项目已经停止，因此这些研究的继续将在一段时间内被搁置。
