Texture modification by addition of ca in Mg-Zn-Y alloy

Abstract

The secondary solidification phase of icosahedral (I-) phase in rolled Mg-Zn-Y alloy is replaced with I + Ca 2Mg 6Zn 3 phases by addition of Ca. Addition of Ca in Mg-Zn-Y alloy 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 α-Mg solid solution matrix may play a role in weakening of basal texture rather than particle stimulation nucleation effect by the second solidification phases. © 2012 The Japan Institute of Metals.
