ACTIVATING EFFECT OF BORON MICROADDITIONS ON SINTERING OF POWDER ALLOY BASED ON IRON

摘要

Results are provided for a study of the effect of elemental boron microadditions on processes occurring during sintering of alloy Fe - 13 wt.% Mn - 1 wt.% C. It is established that microstructure formation is accelerated in the presence of boron. The activating effect of microadditions is explained by the surfactant qualities of boron, and in fact precipitation of boron at all surface nanolayers and a change in their energy condition.
