Accelerated precipitation behavior of cast Mg-Al-Zn alloy by grain refinement
TL;DR: This paper showed that the precipitation behavior of β-Mg 17 Al 12 phase during aging and the resultant variation in hardness and mechanical properties of cast Mg-Al-Zn alloy are strongly dependent on initial grain size.
Journal ArticleDOI
Influence of Bi addition on dynamic recrystallization and precipitation behaviors during hot extrusion of pure Mg
TL;DR: In this paper, the effects of Bi addition on the dynamic recrystallization (DRX) and dynamic precipitation behaviors during hot extrusion of a pure Mg and the resultant microstructure and mechanical properties of the extruded materials were investigated.
Journal ArticleDOI
Dynamic recrystallization behavior and microstructural evolution of Mg alloy AZ31 through high-speed rolling
TL;DR: In this article, the authors investigated dynamic recrystallization (DRX) behavior and microstructural and textural variations of Mg alloy AZ31 during a high-speed rolling (HSR) process.
Journal ArticleDOI
Improvement in extrudability and mechanical properties of AZ91 alloy through extrusion with artificial cooling
TL;DR: In this article, the authors demonstrate that the application of artificial water cooling during extrusion effectively increases the extrudability of the AZ91 alloy and significantly improves the mechanical properties of the extruded Mg alloy.
Journal ArticleDOI
