Abstract

Structural features of a glassy Cu₆₀Zr₃₀Ti₁₀ alloy are studied by using the real-space pair distribution and radial distribution functions. The experimental X-ray diffraction data obtained in a synchrotron beam were used to derive radial distribution function through Fourier transformation processing. Based on these and the results of transmission electron microscopy observation it is suggested that a certain degree of medium-range order in this alloy maintains up to about 2 nm distance. It is also shown that the interatomic distances closely correspond to those of oC68 Cu₁₀Zr₇ compound which allows obtaining high relative density of the glassy alloy. The formation of icosahedral local order is also presumed.
