摘要(Abstract)：

弛豫也称为Johari-Goldstein弛豫,是过冷液体和金属玻璃的固有特征,在过去的几十年一直是材料领域的研究热点.金属玻璃中许多关键本质问题都和弛豫行为(特别是β-弛豫)相关联,因此研究金属玻璃的β-弛豫行为对理解金属玻璃的玻璃化转变现象、机械性能、扩散、物理老化的机制、以及金属玻璃的稳定性都有着很重要的意义.本文简要介绍了金属玻璃β-弛豫的相关研究内容,包括β-弛豫的测试和特征,合金成分对其的影响,以及金属玻璃的塑性与其β-弛豫行为的关联,最后对金属玻璃β-弛豫的研究进行了总结和展望.

关键词(KeyWords)： 金属玻璃;β-弛豫;玻璃转变;非晶性能
