Mössbauer spectroscopy was used to compare Fe-Cr-Ni alloys prepared by different electrochemical as well as thermal methods. The main phase of the electrodeposits was ferromagnetic contrary to the thermally prepared alloys of same composition, which were paramagnetic. Obvious differences can be observed among the spectra of electrodeposited samples of different composition. Narrower line width and smaller paramagnetic contribution can be observed in samples electrodeposited onto A1 substrate compared to those in samples plated onto graphite with modified electrochemical parameters. Changes in hyperfine field distribution of as-deposited and aged samples indicate a precipitation process due to the heat treatment.
