Abstract: he Debye temperature ΘD = 411 ± 12 K was determined for a σ-Fe55.4Cr44.6 alloy, with average grain size of 27 nm, from Mössbauer spectra recorded in the temperature range of 4–300 K. The result fits well with those found previously for samples of different Cr content, x, with mean grain sizes in the micrometre range. ΘD was found to increase linearly with x at the rate of 14.6 K/at.%.
