学术成果与科研项目简介

学术成果：吴戈教授在金属材料强韧化的研究中，提出一种创新材料设计理念——“超纳结构”。超纳意为结构特征尺寸小于10 nm，在此尺寸下材料会表现出一些奇异的性能。巧妙地利用超纳结构设计，在晶态和非晶合金中大幅提高了合金的强韧性。代表性成果包括：1）在晶态材料中，利用超纳析出相和短程序界面结构设计，实现2.6-GPa级超高强合金的优异均匀延伸率；2）在多晶材料和非晶材料中，引入超纳非晶相，大幅提高材料的强度至近理论极限，且同时实现均匀塑性变形；3）物理气相沉积超纳结构合金的实用化可行研究：大幅提升基体合金和3D打印结构的力学性能或使役性能。相关研究为新型超强、高韧合金的研发及其在高载耐磨涂层、微纳芯片等方面的应用提供了纳米结构基础、理论和实验依据。相关成果以第一作者/通讯作者在Nature（封面文章）、Science、Nature Communications（6篇）、Science Advances、Advanced Materials、Materials Today等期刊发表，获“非晶杰出青年科学家奖”（当年全国5人）等。担任陕西省电子显微镜学会常务理事。期刊Journal of Materials Science & Technology青年编委。
