Anisotropy of strengthening by solid solution and precipitation in concentrated Mg-Al and Mg-Zn alloys. The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys.

The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys. Easier prismatic slip lowers the strain hardening rate and increases the ductility of polycrystalline alloys in comparison with pure Mg. Despite their obvious significance, these effects have not been studied in single crystals of concentrated alloys. This is the main object of this project.Read moreRead less
