Abstract
The type of stressed state (compression, simple shear) is shown to effect the parameters of a work hardening curve for Mg single crystals under basic slip. The electron‐microscopic results for the dislocation structure are indicative of the fact that work hardening at stage A of the work hardening curve is connected with the basis‐basis dislocation interaction, while the to‐B‐stage transition and a rapid growth of strain stress are due to the interaction between basic dislocations and “forest” dislocations in the {1010} {1120} systems, the latter dislocations arising from the stress relaxation in the primary slip system.
