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——“晶体-非晶纳米双相结构”。这种理念使用纳米尺寸非晶相取代传统晶态合金中的晶界,可有效克服晶界软化效应。代表性成果包括:1)开发出结构特征尺寸小于10纳米的晶体-非晶纳米双相结构镁基合金,提高材料的强度至接近理论极限;2)通过晶态固溶体替换金属间化合物晶体相,激活晶体相的应变硬化与纳米级非晶相的均匀塑性流变,解决脆性问题,设计并制备出了兼具超高强度和高塑性的高熵合金及铝合金;3)物理气相沉积纳米双相非晶合金以及晶体-非晶纳米双相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)、Nature Communications5篇)Science Advances、Advanced MaterialsMaterials 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、秘书长。期刊Journal of Materials Science & Technology青年编委。
