Comparative study of extrudability, microstructure, and mechanical properties of AZ80 and BA53 alloys

Sang-Cheol Jin et al.

Summary: In this study, the extrudability, microstructural characteristics, and tensile properties of Mg-5Bi-3Al (BA53) alloy were compared with those of the commercial Mg-8Al-0.5 Zn (AZ80) alloy. BA53 exhibited better extrudability without surface cracking compared to AZ80. Both alloys exhibited recrystallized microstructures with a basal texture when extruded at different speeds, but BA53 had a coarser grain structure due to grain growth promoted by high temperature. The presence of Mg3Bi2 particles contributed to the high tensile yield strength of BA53.

Influence of extrusion conditions on microstructure and mechanical properties of Mg-2Gd-0.3Zr magnesium alloy

Tianshuo Zhao et al.

Summary: Different extrusion conditions can affect the microstructure and mechanical properties of magnesium alloys. Increasing extrusion speed and annealing time can accelerate the growth of recrystallized grains and increase elongation. Large pre-forging deformation can refine the grains and increase the strength of the alloy. Decreasing extrusion ratio or increasing cooling rate will introduce coarse un-DRXed grains and transform the texture. Rapid cooling also has an obvious effect on refining recrystallized grains.

Evading strength-corrosion tradeoff in Mg alloys via dense ultrafine twins

Changjian Yan et al.

Summary: The study demonstrates that ultrafine grained Mg alloys with dense twins exhibit high strength and reduced corrosion rate compared to conventional ultrafine grains, achieved through a carefully designed multi-directional compression treatment refining grain size down to 300nm. This technique not only decreases micro-galvanic corrosion tendency, but also completely suppresses severe localized corrosion.
