Abstract
The structure and mechanical properties of copper condensates with a thickness of 0.8...2.0 mm, dispersion-strengthened with chromium, zirconium oxide and their mixture, obtained by simultaneous electron beam evaporation of the selected components with subsequent condensation of the vapor phase onto flat steel substrates, were investigated. It is shown that the characteristics of the structure and the level of strength of the composites depend on the volumetric content of the strengthening phase, its dispersion and total action of the dispersoids. 10 Ref., 12 Fig.
Keywords: electron beam vapour phase technology, thick vacuum condensates, copper, copper-chromium, copperoxide, copper-chromium-zirconium oxide systems, microstructure, hardness, strength, ductility
