Abstract
Crystalline Fe{sub 25}Zn{sub 75} powder alloys ({Gamma}{sub 1} phase) have been prepared by mechanical alloying of pure elemental powders. A crystalline Fe{sub 27.9}Zn{sub 72.1} alloy ({Gamma} phase) was obtained after adequate annealing. The Moessbauer spectra at room temperature displayed three doublets before annealing, corresponding to iron atoms located at the outer tetrahedral, inner tetrahedral and octahedral sites in the unit cell of Fe{sub 25}Zn{sub 75}. For the annealed sample, two doublets associated with iron atoms located at two tetrahedral inequivalent sites in the unit cell of Fe{sub 27.9}Zn{sub 72.1} were observed. This {Gamma}{sub 1}-to-{Gamma}-phase transition was confirmed by X-ray diffraction and Moessbauer spectroscopy measurements. (orig.)
