Hyperfine interactions at iron sites in amorphous Fe2Zr alloys

Amorphous Fe2Zr samples were obtained by mechanical grinding from the intermetallic crystalline phase and by mechanical alloying starting from the elements. We used X-ray diffraction and Fe-57 Mossbauer transmission spectroscopy to monitor the amorphization process and to investigate the alloys prepared by the two methods. The Mossbauer data have been analysed accounting for the disorder proper to a glass structure. The probability distributions of the quadrupole splitting and isomer shift in the amorphous Fe2Zr samples are discussed. (C) 1997 Elsevier Science Ltd. All rights reserved.
