Abstract

The effect of boron on the sintering of iron powder was investigated. Boron (0–400 ppm) was added to high-purity iron powder of the German firm “Mannesmann.” Powder mixtures were pressed to compacts of identical density and sintered at different temperatures in different atmospheres. The results indicated the absence of a liquid phase and no influence of boron in the high-temperature stage of sintering. However, boron additions substantially improved sintering at low temperatures (up to 800°C) due to an effect on the interparticle contacts. With a properly selected sintering regime, microadditions of boron substantially increase the density of sintered ingots.
