简历：
1989年沈阳理工大学本科毕业；1999年4月获工学博士学位（大连理工大学和中科院金属研究所联合培养）。攻读博士学位期间研究金属间化合物的强韧化机理。2000-2003年连续在韩国浦项科技大学（Pohang University of Science and Technology）、以色列本-古里安大学（Ben Gurion University）、法国格勒诺布尔国家理工学院（Institute of National Polytechnic of Grenoble, GPM2实验室）参与或负责镁合金材料及其制备成形过程的相关基础研究。2003年回国正式受聘为中国科学院“百人计划”，负责组建“镁基轻质材料及其应用”创新课题组；已负责 “863”计划，国家自然科学基金，“973”计划，科工局设置，美国波音公司，美国通用汽车公司，重大航天工程等委托的镁合金领域项目二十多项。课题组已与德国、澳大利亚、美国、加拿大、日本、以色列、韩国等国际著名的镁合金研发机构建立了较为深入交流合作。2008年-2014年间，SCI收录镁合金领域的学术论文100余篇，总被引超过1000次；已申请发明专利18项（含美国专利2项），其中已授权专利13项（含美国专利一项）。
研究领域：
1) 新型高成形性、高强韧性镁合金成分设计、开发与应用；
2) 镁合金的显微组织与力学性能表征；
3) 镁合金先进成型（铸造、变形）技术研发与应用。
承担科研项目情况：
1. 建立了Mg-Al-Ca，Mg-Zn-Y，Mg-Al-Zn等几种镁合金在铸造凝固过程中枝晶相干点温度、固相分数与晶粒尺寸的关系，阐明了镁合金凝固组织中发达枝晶和粗大晶粒尺寸的形成机理。阐明了几种镁合金铸造缺陷（热裂纹（图1）、疏松等）的形成机理及消除铸造缺陷的铸造工艺设计（造型工艺、浇注和冒口系统设计、冷却速率控制等）的物理冶金原则。
2. 提出并实现了降低镁合金轧制板材的织构峰值强度和增大织构峰值基极偏转角，抑制｛10-11}<10-12>压缩孪生，促进基面滑移和｛10-12｝<10-11>拉伸孪生（图2），显著提高镁合金室温塑性和成形能力的学术思路。
3. 首先报道RE原子对镁不仅具有异常高的强化效果，还显著提高其高温轧制效率，弱化基面织构或使其非基面化。揭示了RE元素（Ｇd, Y等）对镁合金高温变形机制和动态、静态再结晶机理的影响(图3)。初步阐明了镁合金高温变形织构对其强度、室温塑性和成形能力的影响机理。
4. 发展的高强镁合金G04 (金属所内部合金标准牌号) 已在SZ系列、TG、CE等若干重大工程上累计使用超过千件，为这些国家重大航天工程累计减重百余公斤。
5. 设计和实施了具有自主知识产权的技术和工艺，制造了超大型（轮廓尺寸880×500×500mm）薄壁、中空的镁合金铸件，经检测，其内部冶金品质、力学性能、尺寸精度和产品重量均完全满足设计载荷考核要求，并已装配采用。
6. 采用常规工业轧制技术生产了世界上最高室温伸长率（大于43%）（图4），可室温深冲、室温深拉深的大规格、高延展性镁合金冷轧或热轧薄板（注册商标SuperDucMg），见图5；突破了镁合金在工业上不能进行室温塑性成形的技术瓶颈，成果入选中国稀土学会“2010年中国稀土行业十大科技新闻”，相关专利技术已转让企业
