Annotation The structure of 50 microns thick separated from the nonorienting substrate Cu(Ta) vacuum condensates is studied. It is found that Cu(Ta) condensates, obtained at the substrate temperature of 100 °C have a <111> type texture perpendicular to their surface. The degree and nature of the texturing of the grain structure of the copper matrix, which depend on the concentration of tantalum and the substrate temperature is maintained during subsequent annealing. The regularities studied are explained by the formation by tantalum atoms of segregation at the grain boundaries of the copper matrix during the condensation of two-component vapor.
