Mean hyperfine fields at ⁵⁷Fe in dilute iron-based alloys studied by Mössbauer spectroscopy

The room temperature Mössbauer spectra of ⁵⁷Fe were measured for numerous dilute iron-based alloys Fe_1−xD_x (D = Al, Co, Cr, Mn, Mo, Ni, Os, Pt, Re, Ru, Ta, Ti, V, W, Zn), annealed at 1270 K for 2 h before the measurements. The spectra were analyzed using the Hesse–Rübartsch method in order to determine the mean hyperfine magnetic field <B> at the ⁵⁷Fe nuclei as a function of concentration x of the minority component of the alloy. As the binary alloys are one-faze solid solutions of an element D in iron, a linear relationship between <B> and x is observed. The result supports the suggestion that Mössbauer spectroscopy is a useful tool for the study of dissolution of different elements in iron.
