Effects of static recrystallization on texture evolution and formability in Mg-Al-Zn (AZ) and Mg-Li-Zn (LZ) alloys have been investigated. The effect of static recrystallization appears in an opposite way in AZ and LZ alloys, i.e., the basal texture becomes stronger in AZ alloys, while it becomes weaker in LZ alloys. Since LZ alloys have lower c/a ratio than AZ alloys, compression or double twin forms more abundantly in LZ alloys. The accelerated static recrystallization in the compression or double twinned region leads to a weaker basal texture evolution in LZ alloys. Double basal peak intensity maxima in as-rolled state changed into weaker single intensity maximum due to the effect of static recrystallization during post-annealing. As a result, LZ alloys exhibit much enhanced formability than AZ alloys.
