Abstract

The stress–strain curve for Ni single crystals with the [100] compression axis is investigated and the deformation relief and the dislocation structure are studied. It is established that the stages of strain hardening of the single crystals correspond to the formed deformation relief and to predominantly observed dislocation substructure.
