“…This is consistent with the stress-strain curves presented in Fig. 1b, i.e., the stress initially reaches a maximum and then there is a decline, which is in accordance with the findings reported by other researchers in Zr-based BMGs [6,53]. As for the quasi-static cases, both the weakly thermal fluctuation and the enough time for the reconstruction of the material in the shear band contribute to the repeated activation and arrest of the shear band, which eventually results in the relatively large plastic flow as demonstrated in Fig.…”

“…This work indicates that there is a strain rate sensitivity in Vitreloy 106 at intermediate loading rates, in agreement with some of the previous observations at lower and higher strain rates. 6,12,13,19,20,24) Therefore, the strain rate sensitivity in this particular BMG appears to be independent of loading procedure. Further investigations of other BMGs over a wide range of loading rates and stresses will allow the study of possible transitions regions for the mechanical deformation, thus opening the possibility for new applications.…”

“…5,7,1618,20,22,24) Among those who reported a lack of strain rate sensitivity, some observed that the fracture surfaces of BMG specimens damaged from loading at increasing strain rates exhibited similar fracture features, 3) while others observed varying fracture morphologies indicating that different damage mechanisms dominate the fracture process at different strain rates, 6,12,13,19,20,24) suggesting the dependence of fracture morphology on strain rate. It has also been suggested that the strain rate dependence of deformation behavior in BMG varies with material composition, specimen shape and loading procedure.…”

“…Regarding the yielding and failure of BMGs, a Corresponding author: chenxiaoweintu@yahoo.com some macroscopic failure criteria have been suggested and successfully describe the deviation of fracture surface from the maximum shear stress plane [12,13]. However, the micro-mechanism of deformation and failure of BMGs is still under the exploration process [14][15][16][17]. Recently, the simulation based on finite element method (FEM) is gradually employed for investigating the mechanical behavior of BMGs.…”

“…The related macroscopic failure criteria are difficult to describe the failure mechanism completely. Researchers analyzed the failure process based on the change of microstructure of BMGs [15,16], and demonstrated that the free volume will be created during the deformation process and then coalesce together. Micro-voids will be formed due to the coalescence of free volumes and further leads the damage and failure eventually.…”
