刘博宇博士长期从事金属镁变形与损伤机制研究及高品质镁及镁合金研发工作。面向国防军工、航空航天、交通运输等领域对高性能轻质镁及镁合金的重大需求，针对镁塑性差的长期难题，发现与含有大量杂质的工业纯镁相比，经纯净化后的金属镁可以承载很大的塑性变形，并通过创新应用原位测试技术揭示了其良好塑性的内在机制；进一步，针对镁纯净化的重要需求以及现有提纯工艺成本高、难规模化生产的难题，与所在研究团队共同研发了基于气态原子选择性分离的镁纯化新原理和相关技术装备，作为团队骨干攻克了高纯净镁的低成本规模化制备难题，建成国内首条年产千吨3N5A级高纯净镁示范线；未来将基于高纯净镁和全氩气保护自动化冶炼新技术，开展以性能指标优良且稳定为特征的高品质镁合金研发和应用工作。研究成果在Science、Nature Materials、Nature Communications、Acta Materialia、JMST、JMA、中国材料进展等期刊发表，署名发明专利转让9件；获国家自然科学二等奖（2023，第2完成人），陕西省科学技术一等奖2项（2022，第2完成人；2017，第4完成人），中国材料研究学会技术发明一等奖（2023年，第3完成人）、国际镁协会变形镁合金产品奖（2025）等。主讲课程《材料性能》入选国家级一流本科课程（第2完成人）；作为核心骨干入选首批全国高校黄大年式教师团队；培养的研究生获省部级一等奖、国际/国内学会奖、国家奖学金等奖励荣誉多项。

Boyu Liu is a materials researcher at Xi’an Jiaotong University whose research focuses on magnesium (Mg), particularly its deformation and damage mechanisms and the development of high-quality Mg and Mg alloys. His work combines in situ electron microscopy, mechanistic studies, and process development to address long-standing challenges in Mg plasticity and performance.

He showed that high-purity Mg can exhibit substantial plastic deformation compared with impurity-containing industrial Mg, and used in situ TEM to uncover the mechanisms responsible for this behavior. He has also contributed to the development of scalable purification technologies for high-purity magnesium and to the establishment of China’s first 1,000-ton-per-year demonstration line for 3N5A-grade high-purity Mg.

Dr. Liu has published in journals including Science, Nature Materials, Nature Communications, and Acta Materialia, and holds nine granted invention patents. His honors include the Second Prize of the National Natural Science Award of China (2023, ranked 2/5), two First Prizes of the Shaanxi Provincial Science and Technology Awards (2022, ranked 2/6; 2017, ranked 4/5), the First Prize for Technological Invention from the Chinese Materials Research Society (2023, ranked 3/8), and the Deformed Magnesium Alloy Product Award from the International Magnesium Association (2025).
