Development of Texture During Tensile Test at Room Temperature

摘要: The preferential orientation of 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 texture. It is found that a strong texture is developed after tensile stretching in the Mg alloys with different compositions. The occurrence of the texture is predominantly caused by the preferential formation and growth of twins, whose 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 texture.
