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...
