Shear striations and deformation kinetics in highly deformed Zr-based bulk metallic glasses

Mechanical Properties and Deformation Behavior of Bulk Metallic Glasses

“…A negative SRS was reported for Zr 57 Ti 5 Cu 20 Ni 8 Al 10 alloy at strain rates ranging from 10 [114]. In addition, a negative value was obtained [115] for a similar alloy composition, e.g., Zr 52.5 Ti 5 Cu 17.9 Ni 14.6 Al 10 (Vit105) and for Vit105-based composite, at strain rates of 3.3⋅× 10 . In Zr-based metallic-glass coatings with micrometer-scale thickness for the shallow indentation, in which the substrate effect can be neglected, the increase of the penetration rate also leads to the decrease of the hardness [116].…”

“…The effect of strain rate on the flow stress [96] and ductility was studied [97,98] and the results showed that the higher strain rate used facilitates plasticity.…”

Binary Zr–Ni/Co metallic glass films: Role of the structural state on their durability

“…1a 1 and b 1 . For the Zr-44 at.% Ni TFMG, the presence of fine vein-like features implies the deformation mechanism of classical bulk metallic glasses [46][47][48] or Zr-Ni TFMGs [49,22,50]. The different columnar-like growth morphology for the Zr-43 at.% Co TFMG is considered to be mainly influenced by the deposition parameters.…”

Correlation between the microstructures and the deformation mechanisms of CuZr-based bulk metallic glass composites

“…36 After shear banding, the elastic energy stored (| G E |) consists of the increase in the volume free energy and the newly generated interfacial free energy, or/and the dissipated energy in the form of heat within the SBs. 52,54 In our case, the formation of phase transformation can also store and dissipate parts of | G E |, consuming energy in the form of heat and the newly-generated interfacial free energy and so on. 55,56 In fact, the MT is quite pronounced before the formation of SBs especially with increasing f cryst .…”
