用低于玻璃化转变温度的等温退火法对一种大块金属玻璃进行了结构弛豫。利用示差扫描量热法和仪表化纳米压痕技术研究了结构松弛对复合材料热性能和力学性能的影响。DSC曲线上的热恢复表明，热不稳定的缺陷通过结构弛豫被湮没。在纳米压痕过程中，结构松弛对锯齿状塑性流动行为没有显著影响。然而，结构松弛对硬度和弹性模量的提高都有明显的作用，这归因于松弛导致的热不稳定缺陷的湮没。
Structural relaxation by isothermal annealing below the glass transition temperature is conducted on a Zr64.13Cu15.75Ni10.12Al10 bulk metallic glass. The effect of structural relaxation on thermal and mechanical properties was investigated by differential scanning calorimetry and instrumented nanoindentation. The recovery of the enthalpy in the DSC curves indicates that thermally unstable defects were annihilated through structural relaxation. During nanoindentation, the structural relaxation did not have a significant influence on the serrated plastic flow behavior. However, Structural relaxation shows an obvious effect in increasing both the hardness and elastic modulus, which is attributed to the annihilation of thermally unstable defects that resulted from the relaxation.
