摘要: 金属玻璃是1960 年被发明的新材料,多年以来被各国科学家广泛而深入地研究。与相应的晶态合金相比,这种材料展现出非常独特的力学与物理性能,使之在多个领域都有广阔的应用前景。同时,金属玻璃作为结构无序材料中一类相对简单的代表体系,是研究非晶态物理的一个比较理想的材料模型。解决金属玻璃中的基本科学问题,比如它的结构表征、形变机理、玻璃转变、玻璃形成能力等,不仅可以促进金属玻璃本身的应用,而且也将推动整个凝聚态物理学的发展。

Abstract: First discovered in 1960, metallic glasses have been intensively studied in the last few decades. Comparing with their crystalline counterparts, metallic glasses exhibit some excellent mechanical and physical properties, which make this new kind of materials attractive in a lot of practical applications. Moreover, as one of the typical and simple systems of amorphous materials, metallic glass is seen as a good model system for investigating the fundamental problems in non-crystalline state physics. Not only the obstacles for application of this particular material could be removed, but also the great advance in condensed matter physics would be obtained if the now fundamental problems in metallic glasses, such as structure, deformation, glass transition, glass formation ability and so on could be solved.

Key words: metallic glass, non-crystalline state physics, amorphous material, glass transition
