Abstract
Abstract
The paper describes the results of experimental studies of the superplasticity of ultrafine-grained (UFG) high-purity copper, as well as UFG copper alloys Cu-Ag and Cu-Cr. The study shows that the introduction of small (up to 0.1 wt.%) additives of alloying elements leads to an increase in the ductility of UFG copper at elevated temperatures. An increase in the concentration of alloying elements complicates the process of plastic flow of UFG copper at elevated temperatures due to the difficulty in grain-boundary sliding.
