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 fr om the elements. We used X-ray diffraction and Fe-57 Mossbauer transmi ssion spectroscopy to monitor the amorphization process and to investi gate the alloys prepared by the two methods. The Mossbauer data have b een analysed accounting for the disorder proper to a glass structure. The probability distributions of the quadrupole splitting and isomer s hift in the amorphous Fe2Zr samples are discussed. (C) 1997 Elsevier S cience Ltd. All rights reserved.
