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.
