Abstract

The relations between the mechanical properties of amorphous alloy nanowires and their intrinsic deformation defects are elucidated. In particular, the size effects on the deformation mechanisms which are caused by the density of deformation defects in the interiors of nanowires are quantitatively determined by phase-field modeling. The simulation provides deep insights into the emergence of ductility in amorphous alloy nanowires. The fractures of the amorphous alloy nanowires are found to be well characterized by an avalanche model with some features of self-organized criticality.
