Abstract

The Cu12.6Zr40.5Al46.9 and Cu32.7Zr6.7Al60.6 amorphous alloys are synthesized in metallic multilayered films by ion beam mixing in the present study. Formation mechanism of amorphous phases is discussed in terms of the atomic collision theory. To further analyze the structure and composition of the obtained Cu–Zr–Al metallic glasses, structure factor S(q) is calculated based on the results of molecular dynamics simulations. It is found that the Cu12.6Zr40.5Al46.9 and Cu32.7Zr6.7Al60.6 metallic glasses are mainly consisted of Al–Zr and Al–Al, Cu–Cu amorphous phases, respectively. The calculated results turn out to match well with the experimental observation.
