The effect of alloying molybdenum additives on the hyperfine structure and corrosion-electrochemical behavior of Fe-Cr alloys

Abstract

With the use of Mossbauer spectroscopy, the effect of alloying molybdenum additives on the hyperfine magnetic and electronic structure of iron alloys containing ∼21 and 28% chromium is studied. Probability distribution functions of hyperfine magnetic fields P(Heff), intensities of the effective magnetic field Heff, isomer (chemical) shifts δ, second-to-third spectral line area ratios (W23), and other spectral parameters are calculated with the use of the Normos program package. The data of Mossbauer spectroscopy are compared to the corrosion-electrochemical behavior of the alloys.
