Study on nanocrystalline bulk copper preapred by selective dissolving

Popis výsledku v původním jazyce

Metallic nanoparticles and bulk nanocrystalline materials became very popular recently. The nanomaterials can be utilized in wide spectrum of possible applications. It is due to their good mechanical properties such as high hardness and strength of the bulk materials and high specific surface or catalytic activity of nanoparticles. There are various methods how the nanocrystalline metals can be produced e.g. precipitation from liquids, rapid solidification or vapor deposition techniques. In this work, copper nanoparticles were prepared by selective dissolving of the aluminium matrix from rapidly solidified AlCu40 (wt. %) alloy in the sodium hydroxide solution. The prepared copper powder was characterized by various analytical techniques (e. g. electronmicroscopy and X-ray diffraction) and consequently uni-axially compacted. Mechanical properties of bulk samples were examined by microhardness testing.
