AB The fabrication of soft magnetic Fe parts by the medium-frequency electrical resistancesintering (MF-ERS) technique is studied in this paper. This consolidation technique involves thesimultaneous application to metallic powders of pressure and heat, the latter coming from the Jouleeffect of a low-voltage and high-intensity electric current. Commercially pure iron powder was usedin the consolidation experiences. The porosity distribution, microhardness, electrical resistivity andhysteresis curves of the final compacts were determined and analysed. The results obtained werecompared both with those of compacts consolidated by the conventional powder metallurgy (PM)route of cold pressing and vacuum furnace sintering, and with fully dense compacts obtained bydouble cycle of cold pressing and furnace sintering in hydrogen atmosphere
