金属玻璃的弛豫动力学研究非常复杂,极具挑战性.弛豫(α弛豫、慢β弛豫和快β弛豫)发生在不同的温度下.利用模拟可观测微观原子信息的优势,评述了模拟中3种典型弛豫的特征和机理,并讨论了它们对材料力学性能的影响.讨论了近年来通过模拟方法获得的与弛豫相关的动力学、结构和物理机理方面的研究进展.本综述有助于认识玻璃的本质,建立玻璃材料的动力学-结构-性能关联.
Relaxation Behavior in Metallic Glasses and Related Mechanisms by Simulation Method:A Brief Review
The relaxation dynamics of metallic glasses,as one of the most challenging issues,is complex.The relaxation,including a relaxation,slow β relaxation,and fast β relaxation,occurs at different temperatures.Taking advantage of the microscopic atomic information of simulation,the characteristics and mechanisms of these three typical relaxations were summarized to discuss their influence on mechanical properties of metallic glasses.Recent progresses on dynamical,structural,and physical mechanisms by simulation method were discussed.This review is beneficial to understand the nature of glass and to establish the dynamics-structure-property relationship of glassy materials.
