Abstract
Bulk metallic glasses (BMGs), due to their unique long-range disorder, have a series of intriguing mechanical, physical and chemical properties, showing widespread potential applications. However, plastic flow of BMGs at room temperature is prone to be highly localized into nanoscale shear bands, incurring very limited ductility prior to catastrophic fracture and impeding their further applications. Therefore, clarifying the mechanism of initiation and propagation of shear bands is of central importance in practice. From the scientific viewpoint, the very basic question is why and how a shear band with a characteristic thickness (~10 nm) forms in such an atomically disordered medium. Considerable attention has been attracted to shear banding in BMGs during the past decades. This chapter reviews the recent advances in this aspect, including experiments, continuum, atomistic modelling and theoretical developments.
