Abstract
The mechanism of formation and propagation of shear bands on the surface of a model Co69Fe4Cr4Si12B11 alloy amorphous wire 90 μm in diameter without a glass cover, which was subjected to different types of loading, such as uniaxial tension, drawing, bending, and torsion, is studied. For all applied loadings, the wire exhibits the ability to forming at a retained amorphous state. Depending on the type of loading, deformation is distributed either uniformly along the wire or is localized in a stress concentration zone. In this case, the contributions of forming mechanisms, namely, elastic deformation, ductile flow in the volume, and formation of shear bands on the wire surface, change. The wire is concluded to exhibit the pseudoplasticity effect.
