Angell在20世纪80年代提出的液体fragility概念,为认识玻璃态本质打开了一扇新的窗口,是联系玻璃形成液体和固体的纽带。目前,玻璃转变的主流理论（如模态耦合理论、势能形貌等）围绕fragility展开的研究已经成为玻璃科学领域的一个热点；fragility与玻璃固体基本力学性能之间的关联研究为力学工作者开辟了一片新的研究领域。本文将就玻璃态转变相关基本现象、表征玻璃态转变动力学行为的代表性理论、液体fragility与玻璃固体力学性能关联研究现状进行分析评述,并就本领域今后值得关注的问题进行展望。 |

The concept of liquid fragility, firstly introduced by Angell in the 1980s, has provided new insight on the nature of glassy state and built a bridge between the glass-formed liquids and the resulting solids. The study on the glass transition based on fragility and Mode coupling theory or potential energy landscape has become an area of intensive research in recent years. Exploring the correlation between the fragility of liquids and the basic property of the corresponding glass phase should be a promising field for mechanics. In this paper, the basic phenomena and several dominant theories about the glass transition, the development of the relationship between the fragility and the basic property of glasses are first reviewed, and then several points that deserve further investigations in this field are proposed. |
