Substructural transformations in Cu - 12 at.% Al single crystals with [001] deformation axis
A detailed study of the relationship of the deformation substructures with the stages of plastic deformation of Cu - 12 at.% Al single crystals with [001] orientation of the compression axis at room temperature is presented. The panoramic electron microscopic images of the defect microstructures formed at different stages of deformation have been obtained. The stages of stress-strain curve are associated with the types of dislocation substructures formed during deformation. A diagram of substructures fracture depending on the degree of strain is given. A characteristic feature of the alloy is a micro-twin substructure that appears in the third stage of deformation.
