Static recrystallization of a high strain rate compressed Mg-1 Zn (wt.%) alloy was investigated using electron backscattered diffraction (EBSD). A novel 53°〈101¯0〉 structure observed in the as-deformed alloy, which showed {101¯2}-{101¯2} double twin relationship with matrix. When annealed at 200 °C, {101¯1} compression twins and {101¯1}-{101¯2} higher priority to recrystallize. In addition, coarse {101¯2} tension their inner were preferentially recrystallize, while lenticular had little impact on recrystallization. Therefore, obtaining more or instead can be an effective approach manipulate process deformed Mg alloys.
