AB  - This paper presents the production of sintered materials from nano-composite powders obtained by a novel synthesis method, which represents a combination of thermochemical synthesis and mechanical alloying. Produced powders were characterized by an average individual particle size of 30nm, with the presence of a small number of aggregates with a size of 150nm. The positive effect on dispersion strengthening of the copper matrix occurred up to 1 wt.% Al2O3, whereas a further increase of the Al2O3 content showed a negative effect on hardness. The new synthesis method is more suiTab. for composite materials containing maximum 1wt.% Al2O3. By this novel method it is possible to produce composites possessing a good combination of hardness and electrical conductivity.
AB  - U ovom radu je predstavljena proizvodnja sinterovanih materijala iz nano kompozita dobijenih novom metodom sinteze, koja predstavlja kombinaciju termo-hemijske sinteze i mehaničkog legiranja. Proizvedeni prahovi se karakterišu srednjom veličinom pojedinačnih čestica od 30nm, sa malim prisustvom aglomerata srednje veličine od 150nm. Pozitivni efekti disperznog ojačavanja se postižu dodatkom do 1 tež.% Al2O3, gde se sa daljim porastom sadržaja Al2O3 uočavaju negativni efekti na tvrdoću materijala. Nova metoda sinteze je pogodna za proizvodnju materijala koji maksimalno sadrže 1 tež.% Al2O3. Ovom metodom sinteze je moguće proizvesti kompozite sa dobrom kombinacijom tvrdoće i električne provodljivosti.

AB  - By hydrometallurgy and powder metallurgy along with prognosis of physical-chemical properties, a synthesis of new improved materials can be successfully performed with in advance pre-set properties which is conditioned by a quality of starting powders i.e. by improving their structure. In accordance with that, this paper presents synthesis of the nanocomposite Cu-Al2O3 powder by thermochemical method and sintering with a comparative analysis of the mechanical and electrical properties of obtained solid samples. Nanocrystaline Cu-Al2O3 powders were produced by thermochemical method through following stages: spray-drying, oxidation of precursor powder, reduction by hydrogen and homogenisation. Characterization of powders included differential-thermal and thermo-gravimetric analysis (DTA-TGA), X-ray-diffraction (XRD) and analytical electron microscopy (AEM) coupled with energetic dispersive spectroscopy (EDS). Size of produced powders was 20-50nm with noticeable presence of agglomerates. Composite powders are characterized with A12O3 homogenous distribution in copper matrix. Powders were cold pressed with pressure of 500 MPa and sintered. Sintering of the obtained samples was performed in the hydrogen atmosphere in isothermal conditions at temperature range from 800 to 900°C and time up to 120 minutes. Characterization of Cu-Al2O3 sintered system included examination of density, relative volume change, electrical and mechanical properties, examination of microstructure by SEM analysis, as well as by EDS. The obtained nanocomposite, which structure is with certain changes preserved in final structure, has provided sintered material with homogenous distribution of dispersive in copper matrix, with exceptional effects of reinforcing and excellent combination of mechanical and electrical properties.

AB  - Contemporary materials with predetermined properties can be successfully synthesized by utilizing the principles of hydrometallurgy and powder metallurgy. The results of developing a new procedure for the synthesis of ultrafine and nanocomposite powders based on copper, silver and alumina are presented in this paper. A two-component nanocomposite powder, Cu-Al2O3, was synthesized by a thermochemical procedure, by deposition from an aqueous solution of soluble metal salts, Cu(NO3)(2) and Al(NO3)(3). A three-component Cu-Ag-Al2O3 powder was produced by mechanically alloying nanocomposite Cu-Al2O3 powder and Cu-Ag powder, synthesized by the thermochemical procedure. The produced powders were characterized by determining the particle specific area, pouring density and fluidness, differential thermal and thermogravimetric analysis (DTA-TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM).
