The steps Fe2O3→Fe3O4, Fe3O4→"FeO" and "FeO"→Fe, during the reduction of self reducing pellets plus charcoal (with volatile matter), between 1 223-1 423 K, were analysed. It was found that typical microstructures of the step Fe2O3→Fe3O4 consisted of transgranular cracks in the hematite particles and the Fe3O4 morphology was probably lamellar. The microstructures of the step Fe3O4→"FeO" were similar to and dependent on the first step of reduction and it was observed the formation of superficial microcracks in the "FeO" phase. The typical morphology in the step "FeO"→Fe was that of Fe whiskers between 1223-1323 K, but at 1423 K the found morphology was a mixed one, that is a dense morphology (clusters of cone shaped whiskers) adjacent to a porous morphology of iron.
