Constitutive Rheological Modeling of Flow Serration Behaviour in Metallic Glasses Showing Nanocrystallization during Deformation

Figure 4

Schematic representation of rheological model for mechanical behaviour of individual shear band in light of experimental results (Figure 1) and the proposed micromechanism of deformation in metallic glasses (Figure 3). Interatomic resistance (stiffness) is followed by shear softening (𝜂_𝑠), acting in parallel with hardening induced by in situ nanocrystallization (𝜂_𝑐).
