Effect of pre-straining on twinning, texture and mechanical behavior of magnesium alloys A-review

Introducing {10 (1) over bar2} < 1011 > 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 prestraining 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. (C) 2020 The Author(s). Published by Elsevier B.V.
