三、学术成果介绍

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在Nature（封面文章）、Nature Communications、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。担任期刊Materials Research Letters青年编委。
