Schematic drawings of the precompression treatments on vit4 BMG rod samples.
Compressive engineering stress-strain curves of vit4 BMGs in different conditions.
(a) SEM observations on side surface of treated vit4 BMGs. (b) Magnified views of shear bands in the dotted rectangle in (a). (c) Shear bands on the side surface of treated vit4 BMGs after fracture by compression. (d) Magnified views of shear bands in (c).
von MIses stress distributions simulated based on 2D boundary conditions by using finite element method on a sample with tapered-end subjected to a load F.
Schematic illustration of competitions among three types of shear bands: (a) shear band C dominates, like the situation in the present case, (b) shear bands B in dominance, (c) shear bands A in dominance.
