研究了长径比为0.67-2.00的Zr 59 Cu 20 Al 10 Ni 8 Ti 3块体金属玻璃样品的压缩变形和断裂特征。玻璃的压缩塑性应变随长径比的减小而单调增加，但最大强度几乎保持在1.77-1.88 GPa的恒定值。如果通过主剪切带的旋转进行修正，则所有压缩剪切带角都等于0.40 °。
The compressive deformation and fracture features of Zr59Cu20Al10Ni8Ti3 bulk metallic glassy samples with aspect ratios in the range of 0.67–2.00 have been investigated. The compressive plastic strain of the glass monotonically increases with decreasing aspect ratio, but the maximum strength almost maintains a constant value of 1.77–1.88 GPa. All the compressive shear-band angles are equal to ∼40° if modified by the rotation of the primary shear bands.
