Szukana fraza: [Abstract = "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 of sodium 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 1.2times."]
