Microstructure and Texture of Magnesium Single Crystals Processed by ECAP

摘要：

Equal channel angular pressing (ECAP) is a promising severe plastic deformation technique for production of ultrafine-grained bulk metals with face centered cubic (fee) structure. However, the process is often complicated in hexagonal close packed (hep) metals such as magnesium due to its low forming capability. In this contribution, magnesium single crystals were processed by ECAP through a single pass in order to reveal processes taking place in hep lattice during severe plastic deformation. The microstructure and texture were investigated by SEMEBSD. The deformed microstructure contains shear bands, recrystallized regions and mechanical twins. Activity of twinning systems and texture formation are discussed regarding different initial orientation of the single crystals.
