Effect of Zr-Ti substitution on microstructure of the Fe-Zr/Ti-Cu-B nanocrystalline alloy
vol. 47 (2009), no. 3, pp. 201 - 208

Fe80Zr7Cu1B12 alloy belongs to the NANOPERM-type family of nanocrystalline alloys. In this work, we concentrate on the study of mutual relation between microstructure, hyperfine magnetic fields and substitution of Zr by Ti using Mõssbauer spectrometry, X-ray diffraction and transmission electron microscopy. A complete substitution of Zr by Ti in the amorphous alloy has led to a decrease of the mean hyperfine field by almost 1 T. Nevertheless, a partial substitution, i.e. Zr4Ti3 has no appreciable effect on the magnetic behaviour. After extensive annealing, this alloy shows the lattice parameter of 2.866 Å that indicates almost pure bcc-Fe phase. Such perfect arrangement of the nanocrystallites is, however, not observed in the Zr7- and Ti7-containing nanocrystalline alloys.

Key words
hyperfine interactions, NANOPERM, Mössbauer spectrometry, nanocrystalline alloys.
