The purpose of this paper is to study the influence of processing parameters on the microstructural characteristics of sintered powder metallurgy alloys. The specimens were produced from atomised iron powders with different sizes (150 μm). They were compacted at pressures of 600 MPa and sintered for 30 minutes and 120 minutes at 1150 ºC, respectively. The porosity of the sintered samples was analyzed according to their microstructural characteristics and chemical composition.
