Ya. Babanov et al., ATOMIC-STRUCTURE OF BINARY AMORPHOUS-ALLOYS BY COMBINED EXAFS AND X-RAY-SCATTERING, Physica. B, Condensed matter, 209(1-4), 1995, pp. 375-376
Short-range order of amorphous CuxZr1-x(x = 30, 50, 67 at%) and Ni67Zr
33 are studied. In the case of Cu-Zr alloys we use Cu-EXAFS, Zr-EXAFS
and X-ray scattering data. For Ni-Zr alloy Ni-edge chi(k) and DSF are
involved to solve the system of Fredholm integral equations by the reg
ularization method. The partial pair correlation functions (PCFs) are
determined. The nearest neighbourhood of Cu-Zr alloys may be interpret
ed within the framework of a hard-spheres model. In contrast, the Ni-Z
r PCFs exhibit a trend to strong chemical short-range order.
