研究领域

主要从事纳米晶、非晶等亚稳功能材料制备及稳定性研究，金属块体及表面快速凝固理论与技术，特种铸造理论及工艺研究。

主要学术贡献如下：

1 建立了纳米晶粒长大全热-动力学模型。该模型可精确判断纳米晶粒溶质分布的初始状态及其对随后晶粒生长及偏聚的影响。首次提出纳米晶粒生长过程的三阶段：动力学生长阶段;动-热力学转化阶段;热力学稳定阶段。系列成果发表在冶金类一区Acta Mater等期刊上，获得德国哥廷根大学材料学院院长，Acta主编R.Kirchheim教授高度评价。

2 通过极冷、深过冷快速凝固技术及真空热处理技术成功制备高稳定Fe-B纳米晶和Fe-Cu微米晶并深入剖析了快速凝固亚稳相晶粒形成、转变及残余机理。该系列成果发表在一类国际期刊Acta Mater，J. All. Compd等上，评价为成果具有明显创新性。

3 提出并阐明了固态相变中存在的晶粒的正常-异常-正常的交替演变理论。建立了快速凝固中非平衡遗传性在异常及正常晶粒生长与溶质拖拽间产生的本质关联理论。
