The Cu-Fe_3 and Cu-Cr_3C_2 bulk nanocomposites are prepared by consolidation of the mechanically alloyed powders. The structure and properties (density, Vickers microhardness and electrical conductivity) of them have been studied. It is shown that microhardness is equal to 236 HV and 470 HV for a Cu-5 vol.% carbide phase and for a Cu-30 vol.% carbide phase, respectively. The microhardness which can be influenced by the heat treatment temperature depends on the grain size of the Cu matrix. The electrical conductivity values of 38-44% IACS (International Annealing Copper Standard) at room temperature have been found.

In this paper the nanocomposites based on Fe-TiC and Fe-TiN which were produced by mechanosynthesis of the mixture of Fe or Fe-N (82 at.%) and Ti (18 at.%) in toluene for 16 h and subsequent compaction have been studied. The structural-phase composition and morphology of the mechanosynthesized powders were studied by X-ray diffraction analysis, the Mössbauer spectroscopy and electron microscopy. It has been shown that powders of the following composition: a solid solution based on Fe, TiC or TiN, a phase on the basis of Fe_{3}C - are formed by mechanosynthesis. The measurements of microhardness and corrosion resistance of the produced compacts were carried out as well.
