“…Interestingly, for both strain rates the atomic volume increases within the flow-softening regime of the stress-strain curves, suggesting perhaps that the stress drop is associated with an increase in free volume throughout the atomic structure. 13 Furthermore, the magnitude of the increase in atomic volume following yielding increases with increasing strain rate, which is consistent with experimental observations for homogeneously deformed multicomponent glasses. 13,33 For the two different strain rates, both the atomic volume and the stress approach plateau values for applied strains above ϳ0.06.…”

As discussed before, this plateau regime has been attributed to a dynamic equilibrium between the creation and annihilation of free volume.…”

“…[5][6][7] Furthermore, the effect of strain rate on viscosity induced by mechanical deformation has also been linked to changes in configurational enthalpy. 8 However, attributing the deformationally induced softening of liquids to a unique functional relation between shear modulus and stored configurational enthalpy is a concept that has just recently been brought to attention. 3 This concept essentially suggests that conversion of mechanical work into stored configurational enthalpy induces softening via a dependence of shear modulus on configurational enthalpy.…”

“…The free volume model provides a simple and practical model to describe the plasticity of amorphous alloys. The applicability of the model has been well verified and it can qualitatively explain many mechanics properties of amorphous alloys [74][75][76] . In 1979, Argon 77 used "shear transformation" to explain the plastic deformation of metallic glasses and the theory meets well with the experimental observations.…”
