The possibility of activated sintering by combined use of two activating additions is studied by experiment and demonstrated. The combined effect of two types of additives is studied: additives participating catalytically during gas phase generation, i.e., a carbon donor (Na2CO3 or BaCO3), and micro-additions of surface-active element (B). It is established that both combined additives (Na2CO3 + B...
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...
