Abstract
There was considered influence of nanosized carbon additives on structural phase state and properties of the sintered alloys on the copper, iron and tungsten-cobalt base. There was demonstrated that under liquid phase sintering and crystallization process of powder compositions that contain nanosized carbon particles. non-dissolved fraction of nanosized additive could be stands as additional nucleation centers, that promotes atomization of structure. There was established that for alloys that could be form solid solutions with carbon or hardening carbide phases. nanosized diamond- graphite additives increase of hardness of sintered composites and improve its tribotechnical characteristics
