Abstract
The secondary solidification phase of icosahedral (I-) phase in rolled MgZnY alloy is replaced with I + Ca2Mg6Zn3 phases by addition of Ca. Addition of Ca in MgZnYalloy significantly accelerates dynamic and static recrystallization resulting in much fine grain size and more random texture. EBSD analysis indicates that the presence of Ca in the i-Mg solid solution matrix may play a role in weakening of basal texture rather than particle stimulation nucleation effect by the second solidification phases.
