Študij notranje oksidacije v naogljičenih hitrostrjenih trakovih Cu = The study of the internal oxidation in internally carbonised Cu ribbonsRudolf, Rebeka ...In this paper we present a composite with fine dispersion of nano-sized bubbles, which can be formed by internal oxidation of fine dispersed graphite particles. For this purpose the initial pure Cu ... ribbons were internally carbonised to obtain very fine, some 100 nm-sized graphite particles homogeneously distributed in the Cu matrix. By the internal oxidation process the reaction of dissolved oxygen with graphite yields the gas products (CO, CO2) which cannot be dissolved in the crystal lattice of the metal. The gas products are meshed in the space previously occupied by graphite and they have a greater specific volume than the solid graphite, thus establishing the compressive stresses in the metalic matrix and consequently causing the strengthening offect. On the other hand, such stress fields can react with sliding dislocation, whereby they impede the dislocation motion and consequently we would expect that the composite mechanical properties would be improved.Source: Materiali in tehnologije = Materials and technology. - ISSN 1580-2949 (Letn. 41, št. 1, jan.-feb. 2007, str. 53-58)Type of material - article, component partPublish date - 2007Language - slovenianCOBISS.SI-ID - 11119894
