Abstract

The X-ray diffraction method is used to study the short-range ordering of Al87Y5Ni8, Al87Gd5Ni8, Al87Y4Gd1Ni8, Al87Y4Gd1Ni4Fe4, and Al87Gd5Ni4Fe4 amorphous alloys. The structural factors are obtained and the pair correlation functions are computed. The principal structural parameters are analyzed. It is shown that the investigated amorphous alloys are characterized by the topological short-range order based on the close-packed structure of aluminum and Al3Y(Gd)-and Al3Ni(Fe)-type chemical short-range ordering. It is discovered that the replacement of Y atoms with Gd atoms and Ni atoms with Fe atoms weakly affects the topology of the atomic distribution of the aluminum matrix and leads to changes in the character of chemical ordering. This affects the degree of short-range microhomogeneity of the short-range ordering and the dimensions of structural units. [ABSTRACT FROM AUTHOR]
