The structure of copper with a various content of impurities (0.01, 0.03, and 0.1 wt %) is studied after high pressure torsion at room temperature. It is shown that the content of impurities does not affect the true strain (e = 2) required for the onset of dynamic recrystallization (DR). It has been revealed that the temperature–strain-rate conditions (lnZ), which were the same for copper of various purity, are responsible for the degree of the dynamic recrystallization completeness and the respective type of the formed structure. The correspondence between the range of lnZ and the structure type formed during deformation has been established. Impurity dragging prevents grain growth upon postdynamic recrystallization and ensures the formation of a more dimensionally uniform structure at the stage of partial DR. At the stage of developed DR, the content of impurities in copper does not affect the grain size.

Keywords: severe plastic deformation, copper, temperature-compensated strain rate, dynamic recrystallization, postdynamic recrystallization, structure
