Abstract

The structure of an amorphous Cu64Ti36 alloy produced by mechanical alloying was studied by X-ray diffraction (XRD) and extended X-ray absorption fine structure (EXAFS) spectroscopy techniques and modeled through reverse Monte Carlo simulations using the total structure factor S(K)S(K) and the EXAFS χ(k)χ(k) oscillations on Cu K edge as input data. From the simulations the partial pair distribution functions gij(r)gij(r) and the bond-angle distribution functions Θijℓ(cosθ) were determined and, from these functions, average coordination numbers and average interatomic distances for the first neighbors were calculated. We also obtained information about the three-dimensional structures present in the alloy.
