- A series of experiments demonstrated that an addition of Ag into (Cu0.5Zr0.5)100-xAgx amorphous alloys
alters the plasticity of the alloys in a systematic manner. Energy dispersive x-ray spectroscopy (EDS) conducted
on the (Cu0.5Zr0.5)100-xAgx alloys exhibited the presence of compositional modulation, indicating that
compositional separation had occurred. The presence of compositional modulation was also validated using a
combined technique of molecular dynamics and Monte Carlo simulation. In this study, the effect of Ag on the
compositional separation in (Cu0.5Zr0.5)100-xAgx bulk amorphous alloys was investigated to understand the role
played by the phase-separating element on the plasticity of the amorphous alloys.
