A Dilute-Limit Heat of Solution of 3d Transition Metals in Iron Studied with 57Fe Mössbauer Spectroscopy

  • Jan Chojcan

Abstract

The room-temperature 57Fe Mössbauer spectra for binary iron-based solid solutions Fe1−x D x with D = V, Cr, Mn and Co, were analysed in terms of binding energy E b between two D atoms in the Fe-D system. The extrapolated values of E b for x = 0 were used for computation of the dilute-limit heat of solution of D metals in iron. The results were compared with those derived from calorimetric data concerning the heat of formation of the systems mentioned as well as with those resulting from the Miedema’s model of alloys. The comparison shows that our Mössbauer spectroscopy findings are in a qualitative agreement with the available calorimetric data and they are at variance with corresponding Miedema’s values for Fe-Mn and Fe-Co systems.
