Abstract
The preferential orientation of \( \left\langle {10\bar{1}0} \right\rangle \) axis along tensile direction in magnesium (Mg) sheet alloys is still controversial. By using a quasi-in situ electron backscatter diffraction (EBSD) method, the present study provides an interpretation about the origin of the \( \left\langle {10\bar{1}0} \right\rangle \) texture. It is found that a strong \( \left\langle {10\bar{1}0} \right\rangle \) texture is developed after tensile stretching in the Mg alloys with different compositions. The occurrence of the \( \left\langle {10\bar{1}0} \right\rangle \) texture is predominantly caused by the preferential formation and growth of twins, whose \( \left\langle {10\bar{1}0} \right\rangle \) axes are nearly parallel to the tensile direction. In contrast, the dislocation slip only leads to a small-scale change of grain orientations, and therefore is unlikely to result in the occurrence of \( \left\langle {10\bar{1}0} \right\rangle \) texture.
