Received April 3, 2008 Abstract—The hyperfine magnetic and electronic structure of annealed iron alloys containing 9.0, 11.8, and 12.7% chromium is studied using of Mössbauer spectroscopy. Probability distribution functions of hyperfine magnetic fields P(Heff), mean-square intensities of the effective magnetic field Heff, m-sq, average isomer (chemical) shifts , and other spectral parameters are calculated with the use of computer modeling. Data from Möss-bauer spectroscopy are compared to the results of polarization measurements in 1 N H2SO4 solution at room temperature in order to find the correlation between the electronic structure and the passivability of the alloys studied.
