Abstract

Mössbauer spectroscopy and X-ray diffractometry have been used to study electrodeposited Fe1-x-yCrxNiy (10 ≤ x ≤ 24, 25 ≤ y ≤ 36) alloys. The main phase of the as-deposited samples was found to be microcrystalline having f.c.c. structure. The f.c.c. phase of the electroformed samples was ferromagnetic, contrary to the thermally prepared alloys of the same composition, which were paramagnetic. The electrochemically prepared materials also contain some microcrystalline paramagnetic phases. The hyperfine field distribution analysis of the Mössbauer spectra shows, that a precipitation process takes place in the electrodeposits, due to the heat treatment.
