      abstract     = {Strain localization during plastic deformation drastically
                      reduces the shear band stability in metallic glasses,
                      ultimately leading to catastrophic failure. Therefore,
                      improving the plasticity of metallic glasses has been a
                      long-standing goal for several decades. In this regard,
                      nanoglass, a novel type of metallic glass, has been proposed
                      to exhibit differences in short and medium range order at
                      the interfacial regions, which could promote the formation
                      of shear transformation zones. In the present work, by
                      introducing heterogeneities at the nanoscale, both
                      crystalline and amorphous, significant improvements in
                      plasticity are realized in micro-compression tests. Both
                      amorphous and crystalline dispersions resulted in smaller
                      strain bursts during plastic deformation. The yield strength
                      is found to increase significantly in Cu–Zr nanoglasses
                      compared to the corresponding conventional metallic glasses.
                      The reasons for the mechanical behavior and the importance
                      of nanoscale dispersions to tailor the properties is
                      discussed in detail.},
