金属玻璃结合了金属键合和无序原子结构，是金属材料研究的前沿。这一领域的最新进展表明，玻璃物理学中的许多关键问题都与一种重要的弛豫模式密切相关：所谓的二次（β）弛豫。本文综述了金属玻璃中β弛豫的特征及其与其它过程和性质的关系。特别强调了它们在理解玻璃化转变现象、力学性能和塑性变形、扩散、物理老化机制以及金属玻璃的稳定性和结晶方面的当前作用和未来前景。
Metallic glasses, combining metallic bonding and disordered atomic structures, are at the cutting edge of metallic materials research. Recent advances in this field have revealed that many key questions in glassy physics are inherently connected to one important relaxation mode: the so-called secondary (β) relaxation. Here, in metallic glasses, we review the features of β relaxations and their relations to other processes and properties. Special emphasis is put on their current roles and future promise in understanding the glass transition phenomenon, mechanical properties and mechanisms of plastic deformation, diffusion, physical aging, as well as the stability and crystallization of metallic glasses.
