Abstract
Recrystallization texture evolution in a high stain rate compressed Mg-1Zn alloy was investigated using electron backscattered diffraction (EBSD). Besides of the 101¯2 tension twins (T), 101¯1 compression twins (C) and 101¯1-101¯2 double twins (CT), the 53°101¯0 tension-tension double twins (TT) and deviated 75°112¯0 tension twin boundaries (T′) were observed in the as-deformed sample. When annealed, twinning-induced recrystallization occurred in C and CT twins at the very beginning, which was proved to strongly weaken the basal texture due to a strong orientation scattering by the recrystallized grains. In contrast, the recrystallization of TT twins weakened the basal texture insignificantly. In addition, the lenticular T twins tended to de-twin rather than recrystallize, which remained after 24 h annealing.
