제목 Role of phase separating element on the plasticity in Cu-Zr metallic glasses
초록 A series of experiments demonstrated that the addition of Ag into the (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 the compositional separation to have occurred. The presence of the compositional modulation was also validated using a combined technique of molecular dynamics and Monte Carlo simulation. In this study, we investigate the effect of Ag on the compositional separation in the (Cu0.5Zr0.5)100-xAgx bulk amorphous alloys in order to understand the role played by the phase separating element on the plasticity of the amorphous alloys.
