Cu-Fe₃C(Cr₃C₂) Bulk Nanocomposites Prepared by Mechanosynthesis Followed by Magnetic Pulse Compaction

Abstract

The CuFe3 and CuCr3C2 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 Cu5 vol.% carbide phase and for a Cu30 vol.% carbide phase, respectively. The microhardness which can be inuenced by the heat treatment temperature depends on the grain size of the Cu matrix. The electrical conductivity values of 3844% IACS (International Annealing Copper Standard) at room temperature have been found.
