Abstract:	We derive a deformation map governing the transition from homogeneous flow to fracture response in metallic glasses under the influence of external conditions, i.e. applied deformation rates, test temperatures and sample sizes. This model is developed using simplified kinematics describing the shear-banding process, free-volume kinetics and also a phenomenologically based ductile-fracture criterion. The analytically obtained deformation map accurately reproduces an experimentally determined deformation map for a commercially available metallic glass system. © 2011 Acta Materialia Inc.
