TLDR
In this paper, friction stir processing was applied to a magnesium alloy to generate various grain sizes with the same intense basal texture, and subsequent tensile deformation along two orthogonal directions by easy activation or inhibition of basal slip followed the Hall-Petch relationship between yield stress and grain size in both directions.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.

Regulating electrodeposition morphology of lithium: towards commercially relevant secondary Li metal batteries
TL;DR: Considering the large number of physical and chemical factors involved in achieving fine control of Li electrodeposition, it is believed that achievement of the remaining ∼0.5% in anode reversibility will require fresh approaches, perhaps borrowed from other fields.

Elastic and tensile behavior of nanocrystalline copper and palladium
TL;DR: The elastic and tensile behavior of high-density, high-purity nanocrystalline Cu and Pd was determined in this paper, showing that porosity increases with decreasing porosity, and may be significantly affected by a few large processing flaws.

Influence of texture and grain size on work hardening and ductility in magnesium-based alloys processed by ECAP and rolling
TL;DR: In this article, the influence of texture and grain size on work hardening behavior and dynamic recovery of magnesium alloys was studied, in addition to the direct effect of texture through the change in the orientation factor for basal and prismatic slip, effects were found on dynamic recovery and the appearance of stage II of workhardening.
