Local order in amorphous Fe2Zr Prepared by mechanical alloying and mechanical grinding

Amorphous Fe2Zr samples were prepared by mechanical grinding from the intermetallic crystalline phase and by mechanical alloying from elemental powders. The structural changes during milling were monitored by X-ray diffraction. Mossbauer absorption permitted us to follow the transition from the magnetically ordered phase of iron to the paramagnetic state of the final amorphous products. X-ray and neutron diffraction, coupled with Reverse Monte Carlo simulation, were used to extract the partial structure factors for the two samples. The results for the two alloys are compared and discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
