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.
