Fe89.15Cr10.75 alloy in heavily strained and strain-relaxed states was studied by the conversion electrons Mössbauer spectroscopy. Analysis of the spectra in terms of a two-shell model revealed significant differences in hyperfine fields and in distribution of Cr atoms in the two samples. The former were significantly higher for the strain-relaxed sample indicating a lower number of Cr atoms in the two-shell vicinity of Fe atoms. The latter, expressed in terms of short-range order parameters, gave clear-cut evidence that the number of Cr atoms in (a) the nearest-neighbor shell was in the strained sample higher and the one in the strain-relaxed sample lower than expected for the random distribution, (b) the next nearest-neighbor shell was higher in both samples than the value expected for the random distribution, and (c) both shells was for the strained sample higher and for the strain-relaxed one equal to the value expected from the binomial distribution.
