Combined EXAFS and X-Ray Scattering Investigation of Amorphous Zr-Based Alloys
نویسندگان
چکیده
EXAFS spectra for all K absorption edges and X-ray scattering data have been obtained on an amorphous Fe-Zr sample prepared by mechanical alloying and a rapidly quenched Co-Zr one. Partial pair distribution fnnctions have been determined as a solution of an inverse ill-posed problem for the system of integral equations describing combined experimental data. For Fe-Zr and Ca-Zr amorphous alloys we fmd a high degree of chemical order and also non-Gaussian nearest neighbow distribution.

Structure of Sputtered Amorphous Zr-Hf-Si Alloys
Amorphous (Zr,Hf)37Si63 alloys were produced by sputtering. Their total structure factors were determined by X-ray diffraction. Using the methods of isomorphous substitution and Reverse Monte Carlo simulation, the partial pair correlation functions were obtained. The results were compared with the partial functions of amorphous Ti40Si60. In the amorphous alloys under investigation the transitio...
متن کاملX-ray Absorption Spectroscopy
X-ray absorptioń spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom. Such geometrical feature allows to use X-ray absorption spectroscopy for struc...

The internal oxidation o f dilute Pd alloys has been studied by XAS. Pt, Au, Pb and Bi in Pd form no impurity-oxygen complexes. Y, Nb, Gd, Yb, Lu, H f , Th, Zr and Mo precipitate at 1050°C as oxides. In a recent paper /1/ it was shown how X-ray absorption spectroscopy (XAS) can be used to investigate the internal oxidation of impurities in dilute alloys. It was demonstrated in the case of a @Zr...
متن کاملContinuous Cauchy wavelet transform analyses of EXAFS spectra: A qualitative approach
To better understand the extended x-ray absorption fine structure (EXAFS) spectroscopic information obtained for complex materials such as those encountered in Earth sciences, we propose to use the Continuous Cauchy Wavelet Transform (CCWT). Thanks to this method, the EXAFS spectra can be visualized in three-dimension: the wavevector (k), the interatomic distance uncorrected for phase-shifts (R...
