Role of {10–12} twinning characteristics in the deformation behavior of a polycrystalline magnesium alloy
TLDR
In this paper, the activation of specific twin variants depending on the strain path induced a significant difference in twinning characteristics, such as twin morphology, volume fraction of twins with strain, and twin texture, and consequently gave rise to a totally different effect on the deformation.About:

Influence of texture on Hall–Petch relationships in an Mg alloy
TL;DR: In this paper, the influence of changes in crystallographic texture on the Hall-Petch (H-P) relationship for an Mg alloy was investigated, and the texture variations were facilitated by changing the uniaxial tensile loading orientation with respect to the normal direction of the rolled Mg plate.

Plastic anisotropy and the role of non-basal slip in magnesium alloy AZ31B
Sean R. Agnew,Ozgur Duygulu +1 more
TL;DR: In this paper, a combination of experimental and simulation techniques were used to investigate the plastic behavior of wrought magnesium alloy and found that an increased activity of non-basal dislocations provides a self-consistent explanation for the observed changes in the anisotropy with increasing temperature.
