“…• C of the CuFexylene powder samples with t MA = 96 h allow us to obtain a cementite volume fraction of about 30% [11]. One might think that in the case of the Fe30X96 sample the carbide phase is not formed due to oxidation process.…”

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.

“…The nanostructured composites can be prepared in one step, i.e., without preliminary synthesis of the hardening additive. For this purpose, mechanoactivation of metal powders and a solid, liquid or gaseous source of C, O, N, B or P is used [1][2][3][4][5][6][7][8]. The most effective and practically the only way to obtain copper nanocomposites with low amounts of reinforcing components is mechanosynthesis (MS) using a liquid phase (water, liquid hydrocarbons, organic acids, etc.)…”

Copper-chromium carbide composites containing a carbide phase of 20-30 vol% were obtained with the use of solid-and liquid-phase mechanosyntheses, followed by magnetic pulse compaction (MPC) and spark plasma sintering. The morphology, structural-phase composition, density, hardness and electrical conductivity of the composites were investigated. The structure of composites obtained by MPC represents regions of copper matrix hardened by superfine carbide precipitates surrounded by a layer of chromium carbide. In the composites obtained by spark plasma sintering, the copper matrix hardened by superfine carbide precipitates was divided into areas surrounded by a copper-chromium layer. A composite obtained by the MPC of the powders synthesized using solid-phase mechanosynthesis (MS) (copper, chromium and graphite) had the highest values of Vickers microhardness (4.6 GPa) and Rockwell hardness (HRA 69). The best value of electrical conductivity (36% IACS) was achieved using liquid-phase MS (copper, chromium and xylene) and spark plasma sintering. Liquid-phase MS is the only way to synthesize the powder with a small amount of the carbide phase and without contamination.
