Plasticity of amorphous alloys assessed by their homogeneous flow rate

We explored the sole effect exerted by the packing density of an amorphous alloy on its homogeneous deformation and subsequent inhomogeneous deformation. The experiments demonstrated that an alloy with higher packing exhibits a greater degree of homogeneous deformation, whereas the same alloy exhibits less global plasticity associated with inhomogeneous deformation in a typical compression test. We clarify this paradoxical relationship between homogeneous and inhomogeneous deformation by exploring the relationship between the homogeneous flow rate and its effect on shear localization.
