中文摘要：

利用透射电子显微术，研究了Zr55Al10Ni5Cu30块状非晶室温单轴压缩断裂后样品微观结构变化特征，实验观察到由于塑性形变的集中导致的局部区域内自由体积增加现象，表明局部自由体积增加主导着非晶合金的形变行为。

英文摘要：

The microstructural changes in a bulk Zr55 Al10 Ni5Cu30 metallic glass fractured by uniaxial compression at room temperature were investigated by transmission electron microscopy. Free volume increases are observed within localized regions due to the concentration of plastic flow, suggesting that local free volume increasing dominates the deformation behavior of metallic glasses.
