A high-strength Mg–Sn–Zn–Al alloy extruded at low temperature
TL;DR: In this paper, the extruded alloy consists of coarse and fine-grains with a basal texture, which gives rise to the high tension to compression ratio of 0.9, and the fine microstructure is attributed to the dynamic recrystallization and precipitation that occur during the extrusion.

Influence of extrusion parameters on microstructure and texture developments, and their effects on mechanical properties of the magnesium alloy AZ80
Muhammad Shahzad,Lothar Wagner +1 more
TL;DR: In this article, a DC-cast alloy AZ80 has been performed at three extrusion ratios (12, 22 and 44) in the temperature range 175°C, T Â ≥ 350 Â C. The activation of twinning at low extrusion temperatures promotes nucleation of recrystallized grains at the twin interfaces and refines the grains size.

Application of texture simulation to understanding mechanical behavior of Mg and solid solution alloys containing Li or Y
TL;DR: In this paper, the viscoplastic self-consistent model was used to interpret differences in the mechanical behavior of hexagonal close packed magnesium alloys, showing that the plane strain compression textures of the alloys showed an increasing tendency for the basal poles to rotate away from the normal direction towards the rolling direction.

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.

Improving the mechanical properties of magnesium and a magnesium alloy through severe plastic deformation
TL;DR: In this article, equal-channel angular pressing (ECAP) was used to improve the mechanical properties of pure Mg and an Mg-0.9% Al alloy at room temperature by subjecting these materials to severe plastic deformation through the procedure of ECAP.
