Hall-Petch relationship in Mg alloys: A review
TL;DR: In this paper, a review and comments of the past work on the factors influencing k in Mg alloys are presented, and the reason for texture effect on k is analyzed based on the mechanism of Hall-Petch relationship.
Journal ArticleDOI
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.

Guang-Ling Song,Zhenqing Xu +1 more
TL;DR: The crystallographic basal plane dominated rolling surface (RS) of AZ31 Mg alloy has higher corrosion resistance in a chloride containing solution than its prismatic plane dominated cross-section surface (CS) as discussed by the authors.

The onset of twinning in metals: a constitutive description
TL;DR: In this article, a constitutive expression for the twinning stress in BCC metals is developed using dislocation emission from a source and the formation of pile-ups, as rate-controlling mechanism.

Influence of grain size on the compressive deformation of wrought Mg-3Al-1Zn
TL;DR: The influence of the grain size on the flow stress of extruded Mg-3Al-1Zn tested in compression is examined in this paper, where samples with grain sizes varying between 3 and 23 μm were prepared by altering the extrusion conditions.

Mechanical properties and microstructures of an AZ61 Mg Alloy produced by equal channel angular pressing
TL;DR: In this article, the negative slope of yield stress versus d−1/2 in ECAPed AZ61 alloys can be explained by the gradual transition of the texture during repetitive equal channel angular pressing (ECAP) to control the grain size.
