【 摘 要 】

Introducing {101¯2}<101¯1> extension twin and their variants in magnesium alloys is one of the cost-effective practical approaches for re-assigning the crystallographic axes distributions in wrought magnesium alloys. The twin lamellae and variants can significantly refine the grain size through twin boundaries. Besides, the synergetic effect of twin boundaries, twining morphology, twinning variants, and textural changes can considerably increase the formability, yielding behavior, and anisotropic mechanical behavior of the magnesium alloys. Therefore, this review article emphasized the different pre-straining techniques and the underlying mechanisms which were responsible for the changes in the crystallographic texture, enhancing the mechanical strength and exacerbation of anisotropic mechanical behavior. In the end, some scientific problems have been proposed for the further development of the magnesium alloys.
