Abstract
A comparative study of the evolution of dislocation structure accompanying deformation in the alloys Cu-Mn and Cu-Al for concentrations 0–19 at.% Mn and 0.5–14 at.% Al was performed by the method of transmission diffraction electron microscopy. It was determined that the concentration of the solid solution affects the character of the evolution and the parameters of the substructure. It was found that the type of observed substructures are virtually identical for the alloys of both systems, but in contrast to the alloys Cu-Al twinning does not occur in Cu-Mn. In the solid solution Cu-Mn the substructures are observed to change at higher concentrations than in the alloys Cu-Al. It was established that a decrease in the packing-defect energy affects the change in the substructure in the same direction as does an increase in solid solution hardening.
