Abstract

The orientation relationships between the compression twins and their matrices in magnesium were investigated using EBSD technique. Schmid factor analyses were applied to determine the orientation dependency of compression twins and the condition for double twinning. Results show that thin compression twin bands of {10\\bar11} type lose easily their exact twin relation of 56°⟨11\\bar20⟩ to ∼40°⟨11\\bar20⟩ due to the instability of twin orientation and immobility of twin boundaries. And the basal orientation with TD-rotation tends to induce tension twinning in compression twins.
