The lack of tensile ductility in bulk metallic glasses (BMGs) has severely impeded their structural applications. Two important BMG architectures that have been developed to improve ductility are bulk metallic glass composites (BMGCs) and nanoglasses (NGs). In this work, continuum analyses of tensile loading on BMGCs and NGs are performed to gain insights on their tensile deformation response. The results show that high hardening elongated dendrites with substantial volume fraction would make the BMGC ductile without any loss of strength. Also, grains size with respect to intrinsic material length associated with interaction stress between flow defects governs the deformation response in NGs.
