Abstract

The change in microstructure during tensile deformation of magnesium single crystals by basal slip was studied with electron backscatter diffraction in the scanning electron microscope. Two samples were plastically deformed up to shear strains of 0.37 and 1.28 belonging to work‐hardening stages A and B, respectively. The results show that the local misorientations resulting from rotations around the <10$ \bar 1 $0> axis strongly increase the work‐hardening coefficient in stage B. The mechanism of work‐hardening in stage B is discussed with respect to subgrain formation. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Tensile tests on homogenized single crystals of Mg-Sn alloys were performed at room temperature. The hardening, i.e. the increase in critical resolved shear stress (orss) per at.% solute, can be partially explained by short range order (sro). If the part due to sro is subtracted from the overall har

## 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 wor
