MeC-Fe (Me=Nb, Ti, V) composites produced by mechanosynthesis in liquid hydrocarbon medium
Microstructure and microhardness of MeC-Fe (Me=Ti, V, Nb) carbide steels (up to ~70 vol.% of carbides) produced by compaction of the powders mechanically synthesized from the mixtures of Fe and carbide-forming metals in the presence of a liquid organic medium have been investigated. After the powders compaction, formation of the compacts with a complex phase composition was occurred containing MeC carbides, NbFe and Fe Ti intermetallides, and α -Fe(Me) solid solution. Compacts2 2microhardness is 4-7 GPa.
