Abstract Three partial radial distribution functions [RDF’s] are calculated by means of relaxed dense-random packing models for a Fe80B20 glass. The model structures reproduce fairly well recently reported experimental partial RDF's derived from x-ray diffraction and neutron diffraction using isotopic substitutional methods. Most significantly, both the model calculated by means of relaxed dense-random packing models GBB (r), the appearance of a subpeak on the short distance side of the first peak.

Structure of Zr50Ni50Amorphous Alloy Was Analyzed by Anomalous X-Ray Scattering (AXS) Coupled with Reverse Monte-Carlo (RMC) Simulation. Topological Features in the Nearest Neighbor Atomic Configuration Clearly Suggest that the Strong Chemical Interaction between Ni and Zr Breaks the Icosahedral-Like Local Ordering Structure Common in the Dense Random Packing of Hard Sphere (DRPHS) Model. Nevertheless, the Structure of Zr50Ni50Shows No Further Features Related to the Crystal-Like Chemical Short Range Ordering (CSRO).

Abstract Detailed analyses of the x-ray scattering intensities of molten nickel-phosphorus alloys ranging from 0 to 30 at.% phosphorus have been carried out. The three partial structures required to characterize the binary alloys have been estimated. The interatomic distance of P -P pairs was found to be about 3.2 Å, and thus phosphorus atoms cannot exist as nearest neighbours in molten Ni-P alloys, at least within the present experimental composition range. It was confirmed that this arrangement of atoms contributed to the characterisic structure in which the expansion of the Ni -Ni distance was unavoidable. Calculations have also been carried out in terms of the dense random-packing model of binary spheres. The calculations were consistent with the experimental results.
