Abstract: Sigma-phase Fe0.525Cr0.455Ni0.020 alloy was studied by means of M\"ossbauer spectrometry in the temperature range of 5-293 K. The average center shift, <CS>, determined from the recorded M\"ossbauer spectra was shown to significantly deviate from the Debye model in the temperature range below ca. 50 K i.e. in the magnetic state of the sample. The deviation is obviously due to the effect of magnetism on the lattice dynamics of the studied sample. Analysis of the <CS>-data in the paramagnetic phase in terms of the Debye model yielded the value of 437(7) K for the Debye temperature.
