Аннотация For the first time in the conditions of the IR pyrolysis precursor based on polyacrylonitrile, cobalt acetate and acetylacetonate iron (ratio of metals in precursors Fe : Co = 3 : 1) metal-carbon nanocomposites have been obtained, which are carbon matrix with graphite-like structure, containing buried her nanoparticles of intermetallids of FeCo. It is shown that the phase formation FeCo occurs in the temperature range of obtaining 500-600 degrees centigrade, at T ≤ 500 degrees centigrade are only two distinct phases metals: HCC-With and BCC Fe. In the structure of nanocomposites obtained at T ≥ 600 degrees centigrade, at the same time there are nanoparticles of intermetallides and FeCo little content phase fсс-Co or solid solution of cobalt. It is determined that the composition of a metal component nanocomposite satisfies the ratio of Fe, Co, originally specified.
