Abstract
The hot and cold rolled microstructures of a Mg-2.9Y alloy were examined by means of metallography, X-ray texture measurement and EBSD technique. It is found that Y in solid solution suppresses dynamic recrystallization even at 450 °C. After rolling, a heterogeneous microstructure containing twins and bands is obtained. The bands were found to originate form double and compression twins, and are locations of high-stored energy. The bulk texture of the rolled material consists of the typical basal component, and also a component from the ND towards the TD. The latter component results from the presence of parent grains with c-axis along the TD. The strain is accommodated in such parent grains by extension twinning and possibly prismatic slip.
