abstract = {The fabrication of soft magnetic Fe parts by the medium-frequency electrical resistance
sintering (MF-ERS) technique is studied in this paper. This consolidation technique involves the
simultaneous application to metallic powders of pressure and heat, the latter coming from the Joule
effect of a low-voltage and high-intensity electric current. Commercially pure iron powder was used
in the consolidation experiences. The porosity distribution, microhardness, electrical resistivity and
hysteresis curves of the final compacts were determined and analysed. The results obtained were
compared 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 by
double cycle of cold pressing and furnace sintering in hydrogen atmosphere},
