Abstract

Abstract The room temperature 57Fe Mössbauer spectra for binary iron-based solid solutions Fe1−x Os x , with x in the range 0.01 ≤ x ≤ 0.05, were analyzed in terms of binding energy E b between two Os atoms in the Fe-Os system. The extrapolated values of E b for x = 0 were used for computation of enthalpy of solution of osmium in iron. The result was compared with that resulting from the cellular atomic model of alloys by Miedema. The comparison shows that our findings are in qualitative agreement with the Miedema's model predictions.
