Özet
This work focused on the effect of the structural order and dimensionality on the deformation mechanism of Cu-Ag alloy and the triggering factors of this mechanism. It is revealed that (i) the weakness of the system develops from bulk to nanoscale and crystalline to amorphous systems, (ii) Cu-Ag nanowires are more flexible than their bulk counterparts, (iii) crystalline Cu-Ag alloys are stiffer than amorphous systems. The reason for early yielding and less stiffness of amorphous Cu-Ag nanowire with respect to bulk material is the less fraction of ideal icosahedra. Cu atoms are a key factor to characterize the mechanical response of both amorphous Cu-Ag alloys. While there are two different deformation modes in crystalline systems, the only mode observed in the amorphous alloy is homogeneous deformation. The presence of (0,5,2,x) (x = 5,6) polyhedral is the reason for the transition of deformation from homogeneous to inhomogeneous in the crystalline Cu-Ag alloys.
