Abstract

The pair correlation function for Gd4Cu3 metallic glass has been determined using X-ray diffraction. A model for the Gd4Cu3 glassy structure has been selected by comparing the experimental pair correlation function with model ones for disordered cyrstal structures. The structure model has been verified by means of a non-linear squares profile analysis of the experimental pair correlation function. It has been established that the local atomic arrangement in the Gd4Cu3 metallic glass resembles that in tetrahedrally close-packed Zr4Al3-type (Frank-Kasper type) crystalline compounds. Similarity in the topological short-range order of both glassy structures has been found by comparing the characteristic structural parameters of Gd4Cu3 and of Gd4Al3 metallic glasses. This indicates that the second metallic component (Al; Cu) does not play an important role in the formation of the local order in these glasses.
