TL;DR: In this paper, the evolution of twinning and texture in two Mg-based (+Al, Mn, Zn) alloys was investigated using uniaxial tension, unioxial compression and ring hoop tension testing at temperatures from ambient to 250°C and a strain rate of 0.1 s−1.

TL;DR: In this article, the authors investigated the nucleation and propagation of tensile twins in magnesium alloy AZ31 using high-resolution electron backscatter diffraction (HREBSD) techniques.

TL;DR: In this paper, a fine-grained single-phase Mg-Zn-Al alloy (AZ31) was shown to have superplastic behavior with an elongation to failure ratio of 475% at 1 × 10−4 s−1 and non-superplastic behaviour with a deformation ratio of 160%, and the corresponding strain rate sensitivities were 0.5 and 0.2, respectively.

TL;DR: In this paper, an analysis of flow stress and work hardening behavior has been carried out in series of Al-Mg solid solutions between 4-K and 298-K. The results reveal that the yield stress decreases linearly with the temperature and increases approximately linear with the Mg content in the solution.

TL;DR: In this article, a small addition of zinc (about 2%) can significantly improve the strength of the Mg-0.2% Ce alloy and increase the ductility by providing a random texture in the extrusion.
