简要回顾了从20世纪30年代至今,有关非晶合金及合金液体的局域结构五次对称性的实验、理论和模拟研究.在简单液体的早期研究中,人们已经意识到五次对称性在简单液体的无序结构、过冷和晶化等起着重要作用,二十面体短程序作为五次对称性的典型代表受到了广泛关注.自从Frank提出简单液体中二十面体短程序的结构单元,大量的理论和实验研究已经明确在简单液体、合金液体和金属玻璃中存在局域五次对称性,并且建立了局域五次对称性与合金液体复杂动力学行为、玻璃转变、液体-液体相变以及非晶合金的形变等统一的定量描述和物理图像,表明了局域五次对称性作为结构参量的简单、普遍和有效性.
A brief review of the experimental, theoretical and simulation studies on the five-fold symmetry of the local structure of amorphous and alloy liquids has been made since the 1930s to the present. In the early studies of simple liquids, it was recognized that the five symmetry The disordered structure of simple liquid, supercooling and crystallization plays an important role, the icosahedral short program as a typical representative of the five symmetry has received widespread attention since Frank proposed a simple liquid icosahedral short structural unit , A large number of theoretical and experimental studies have confirmed that there are five local symmetries in simple liquid, alloy liquid and metallic glass. Moreover, the local five-fold symmetry and complex dynamics of alloy liquid have been established. The glass transition, liquid-liquid The uniform quantitative description and physical image of the phase transition and the deformation of the amorphous alloy show the simplicity, universality and validity of the local five-fold symmetry as the structural parameter.
