X-ray diffraction study of the structure of amorphous Cu$sub 57$--Zr$sub 43$ alloy
X-ray diffraction patterns have been obtained from a Cu$sub 57$-Zr$sub 43$ alloy in both amorphous and liquid states. After calculating the structure factor by means of the common Fourier analysis, the atomic radial distribution function was evaluated from which interatomic distance and coordination number were obtained. The essential features of the structure factor in the amorphous state were quite similar to that in the liquid state. There is a good agreement between the structure factor determined in this study and that calculated on the basis of the hard sphere mixture model except for the presence of the splitting of a second peak maximum in the former. These results suggest that the atoms in the nearest neighbour distance in the amorphous state are mainly the same disorderly distributed atoms as those in the liquid state. But a deformed crystalline-like arrangement of atoms as those in a hcp or fcc structure contributes partly to the short range order in the amorphous state. (orig.)
