Magnesium and its alloys applications in automotive industry. The effort on the study of magnesium single crystal in the present work contributes to further polycrystalline analysis. Basal slip is found to be easily activated due to a slight deviation, while a slight deviation in the twin-favored case could result in a significant difference in the mechanical behavior after the reorientation. Furthermore, the effect of an initial deviation angle on the mechanical responses was evaluated, which is proved to be also orientation-dependent. It is also found in the simulation that basal slip in the twinned region is active even before the saturation of twin activity in a twin-favored case. The predicted macro-and microscopic responses, along with the experimental results, show strong orientation-dependent properties. Related material parameters were calibrated at first according to the classical channel-die tests. The proposed model was then applied to the simulation of plane-strain compression deformation for different orientations. Twin-induced lattice reorientation was also incorporated in the model. Four deformation mechanisms (including basal 〈 a〉, prismatic 〈 a〉, pyramidal 〈 c + a〉 slip and tension twin) and their interactions were considered. A phenomenological crystal plasticity constitutive model for magnesium single crystal was presented.
