In Situ SEM Torsion Test of Metallic Glass Microwires Based on Micro Robotic Manipulation

Figure 4

Microstructure of the fracture surface. (a) and (c) are the two corresponding sides at the fracture point. There are revolving vein-patterns on both of them. The magnification images of (b) and (d) show that the area between the corrugations is very flat and clean, which may be because the plastic deformation was confined to extremely small space inside metallic glass.
