摘　　要：Developing materials with excellent properties has been the untiring pursuit of mankind.Metallic glasses(MGs)would be the ideal metallic materials if their size could be scaled up to be comparable to traditional metals.To address this challenge,a variety of approaches have been attempted over the past decades,including thermodynamicsbased alloy,3D printing and the recent artificial intelligenceguided optimal alloy.In this study,a facile and flexible route was demonstrated to manufacture giant MGs(GMGs)with diameters more than 100 mm through the thermo-joining process.The jointed GMG samples feature almost the same performance as the as-cast ones.The ability of manufacturing complex 3D components such as the Chinese Zodiacs was also demonstrated.Our approach might overcome the longstanding problem of glass forming ability(GFA)limitations in alloy systems and pave new concept and route to fabricate size unlimited MGs.开发具有优良性能的材料一直是人类不懈的追求.如果将尺寸放大到与传统金属相当的水平,金属玻璃将是一种理想的金属材料.为了应对这一挑战,在过去的几十年中,研究学者们已经尝试了多种方法,包括基于热力学的合金开发、3D打印以及基于人工智能学习的合金优化设计新理念.本文提出了一种简便、灵活的界面设计理念来制造直径大于100 mm的巨型金属玻璃(GMG),通过该方法制造的巨型金属玻璃性能几乎与铸态样品相同.此外,利用该方法可制造复杂三维结构.本文提出的方法为克服合金系统中长期存在的玻璃形成能力(GFA)限制的问题,制造大尺寸、复杂结构金属玻璃开辟了新的思路和途径.
