Abstract
The nanocrystalline alloys were obtained by annealing treatments at several temperatures ranging from 500 degrees C to 530 degrees C for time intervals 10, 20, 40 and 60 minutes. X-ray absorption spectra near the Fe K, Cu K and Cr K absorption edges for the studied alloys were measured in transmission mode at room temperature using synchrotron radiation in HASYLAB. The EXAFS oscillations and magnitude of Fourier transforms exhibited increasing volume fraction of the crystalline phase and ordering of the local bcc-structure around Fe and fee-structure around Cu atoms. It was found that Cr atoms remained in amorphous matrix in the nanocrystalline alloys.
