We report a novel plastic deformation mechanism of bulk metallic glass composites (BMGCs) containing metastable β−Ti dendrites. Plastic deformation of the BMGCs beyond the ultimate tensile strength is mediated by cooperative shear events, which comprise a shear band in the glassy matrix and a contin...
