- 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.
