Abstract

A structural model is proposed for bulk amorphous alloys based on the pair distribution functions (PDFs) measured using neutron scattering at ambient and cryogenic temperatures and different structural states. Reverse Monte Carlo (RMC) simulations were performed, in which icosahedral and cubic structures were used as the initial structures for the PDF refinement. The combined PDF and RMC studies show that strongly bonded clusters, with atomic-bond lengths shorter than their crystalline counterpart structures, are randomly distributed and strongly connected in the amorphous matrix. An attempt has also been made to identify the relationship between amorphous structures and their mechanical properties. © 2006 American Institute of Physics.
