In this paper, the possibility of increasing powder carbon steels properties by activation of carbon diffusion into the iron base during sintering process due to the introduction of the thermally split graphite (TSG), macromolecular compounds (MC) and sodium bicarbonate was investigated. It was found that the introduction of these additives allows obtaining homogeneous structures at a sintering temperature of 100–200 °C lower than that traditionally used for sintering of powder carbon steels. Such structures provide increased mechanical properties of powder carbon steels. The addition ofsodium bicarbonate increases the diffusion rate of carbon into iron at a temperature of 950 C by 1.8 times, at 1000 °C by 1.5 times, and at 1100 °C by 1.2 times.
