李建军,教授,博导,德国洪堡学者,湖南省优青2020年),入选中南大学机电工程学院首批青年人才培育计划2020年)、湖湘青年英才科技计划(2021年)2013年毕业于香港大学机械工程系,获得博士学位,并获香港大学机械工程杰出研究生奖。博士毕业后被西北工业大学聘为副教授,2015年至2017年在德国马普钢铁研究所以洪堡学者身份从事研究,合作导师为德国科学院院士、马普钢铁所所长Dierk Raabe教授。回国后加入中南大学机电学院,任教授,成立了微纳结构材料力学研究所,担任负责人,团队有教授1人、博导2人、副教授4人、硕/博士生10余人。

主持国家自然科学基金面上和青年项目、湖南省自然科学基金、高性能复杂制造国家重点实验室自主研究课题、非线性力学国家重点实验室开放课题等多个国家级课题。团队一直从事纳米结构金属材料力学行为方向的研究,主要关注超高强纳米结构金属材料工程应用面临的两大关键科学难题——强度-韧性对立矛盾、机械/热不稳定性,已取得两个方面的创新成果:

(1) 针对纳米结构金属强度-韧性对立问题:建立了一系列界面非均匀分布的高强高韧纳米结构金属(包括铜、IF钢、镍等)基于物理机制的多尺度本构关系,揭示了非均匀界面微结构(如梯度、双模态)对强韧性能的调控机制;实现了一类高强韧匹配的纳米多层结构金属复合材料的实验制备,并揭示了此类多层结构获得良好强韧性能的变形机制。

(2) 针对纳米结构金属机械不稳定性问题:建立了纳米结构金属机械不稳定性(即应力诱导纳米晶粒长大)的细观力学模型,揭示了应力诱导晶粒旋转的变形机制,提出了晶粒长大两种模式——晶粒旋转与晶界迁移的耦合新机制;指出应力诱导晶粒长大可增强断裂韧性、提高钝化裂纹及晶界处发射位错的能力,是纳米结构金属材料的有效韧化机制。

已发表高水平SCI论文40余篇,包括塑性力学顶刊IJP6篇)、金属材料顶刊Acta Mater.2篇)、Scripta Mater.6篇)、IJSS2篇)、MSEA6篇)、APLPhil. Mag. Lett.2篇)、Mater. Lett.2篇)、J. Appl. Phys.等, SCI引用500余次。研究成果被美国三院院士H.GaoMech Mater副主编F.Barlat、法国技术院院士J. Lu、中科院卢柯院士等国内外著名学者多次直接应用与重点引用。申请人多次在国际国内会议上作学术邀请报告,作为项目负责人承担过国家自然科学基金2项、湖南省自然科学基金1项,担任多个国际学术期刊审稿人,并担任国家自然科学基金青年与面上项目通讯评审人。

目前团队主要围绕以下3个研究方向开展研究:(1)新型纳米结构金属及其复合材料的微结构设计与制备及力学表征;(2)具备梯度、双模态、多模态、多层级等不均匀微结构特征的异构纳米金属材料力学行为研究;(3)纳米结构金属材料的热/机械不稳定性研究。结合微纳米力学测试与表征(原位纳米压痕、微柱压缩、透射/扫描电镜表征等)、原子模拟、本构建模等先进研究方法开展研究。团队已配备纳米结构金属及合金样品制备的高真空磁控溅射仪器及微压痕仪器。可利用学院新配备的透射电镜进行原位力学测试与分析表征,借助中南大学高研中心的双束离子束研磨仪器进行微纳测试样品制备以及三维原子探针APT精确表征元素组分。同时配备了340核计算服务器,可进行千万量级原子模型的计算模拟。欢迎优秀的本科生、硕士生、博士生及博士后加入团队。
