- Experiments in binary alloys demonstrate that metallic glasses exhibiting more plastic strain during
homogeneous deformation tend to show lower global plasticity during inhomogeneous deformation.
Testing of Cu–Zr binary alloys supports the hypothesis that the formation energy of a shear
transformation zone, as extracted from the experimental data, is related to the homogeneous flow
rate. We also report the microstructural aspects that control the global plasticity of metallic glasses
in the light of structural disordering, softening, and shear localization.
