Abstract
Owing to the hexagonal close-packed (HCP) crystal structure of magnesium alloys, they are characterized by poor plasticity at low temperatures (below recrystallization temperature), which limits their application. Texture control has been proven to be an effective way to enhance the ductility, formability, processability, and so on. Various technologies, which can be classified as alloying elements, induced shear deformation, pre-twins, and recrystallization, have been developed to modify the basal texture. Based on these results, the general mechanisms of texture control in various recent methods are summarized. In addition, applications of Mg products via texture weakening below recrystallization temperatures are also reviewed. Finally, the current problems and the potential research directions on texture control are suggested.
