研究領域

主要從事納米晶、非晶等亞穩功能材料制備及穩定性研究，金屬塊體及表面快速凝固理論與技術，特種鑄造理論及工藝研究。

主要學術貢獻如下：

1 建立了納米晶粒長大全熱-動力學模型。該模型可精確判斷納米晶粒溶質分布的初始狀態及其對隨后晶粒生長及偏聚的影響。首次提出納米晶粒生長過程的三階段：動力學生長階段;動-熱力學轉化階段;熱力學穩定階段。系列成果發表在冶金類一區Acta Mater等期刊上，獲得德國哥廷根大學材料學院院長，Acta主編R.Kirchheim教授高度評價。

2 通過極冷、深過冷快速凝固技術及真空熱處理技術成功制備高穩定Fe-B納米晶和Fe-Cu微米晶并深入剖析了快速凝固亞穩相晶粒形成、轉變及殘余機理。該系列成果發表在一類國際期刊Acta Mater，J. All. Compd等上，評價為成果具有明顯創新性。

3 提出并闡明了固態相變中存在的晶粒的正常-異常-正常的交替演變理論。建立了快速凝固中非平衡遺傳性在異常及正常晶粒生長與溶質拖拽間產生的本質關聯理論。
