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.
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.
