At cryogenic temperatures bulk metallic glasses can sustain higher plastic strains than at room temperature. This is generally believed to result from an intrinsic shear-band nucleation rate that increases with decreasing temperature. Here we report on inhomogeneous flow operating via a single shear band even at cryogenic temperatures, challenging the presupposition of increased shear-band activity. The results provide a new interpretation of non-serrated flow and explain, via a simple viscosity law, the correspondingly observed strength increase with decreasing temperature.
