To
harness “smaller is more ductile” behavior emergent
at nanoscale and to proliferate it onto materials with macroscale
dimensions, we produced hollow-tube Cu<sub>60</sub>Zr<sub>40</sub> metallic glass nanolattices with the layer thicknesses of 120, 60,
and 20 nm. They exhibit unique transitions in deformation mode with
tube-wall thickness and temperature. Molecular dynamics simulations
and analytical models were used to interpret these unique transitions
in terms of size effects on the plasticity of metallic glasses and
elastic instability.
