Effect of calcium addition on microstructure and texture modification of Mg rolled sheets

The mechanical properties and texture of AM60 (Mg-6.0Al-0.3Mn, mass fraction %) and ZXM200 (Mg-1.6Zn-0.5Ca-0.2Mn) Mg alloys subjected to multi-pass hot rolling were investigated. The finer recrystallized grains usually exhibit particular preferred orientations and then alter the total texture feature of rolled sheets. Ca solid solution into Mg matrix serves to the formation of texture component with c-axis rotated away from normal direction towards transverse direction and then weakens the overall texture intensity, resulting in a similar anisotropic characteristic to RE-containing Mg alloys.
