Summary: This review investigates the influence of extrusion parameters on the bio-corrosion performance of magnesium alloys. Dynamic recrystallization and grain refinement during extrusion can improve the mechanical properties and corrosion resistance of magnesium alloys. Increasing the extrusion ratio and decreasing the extrusion temperature can further enhance the bio-corrosion resistance of magnesium alloys.

Summary: A high-strength magnesium-lithium alloy was successfully fabricated via cold rotary swaging, resulting in the formation of nanograins with high-angle grain boundaries in the central region, leading to higher mechanical properties compared to the edge region. The nanocrystallization process in the central region involved massive twinning and subsequent refinement of twin/matrix lamellae through the formation of dislocation arrays, while the edge region exhibited lower twinning activity and difficulty in forming dislocation arrays.

Summary: This study investigated the superplastic behavior at intermediate temperatures of a commercial ZK60 magnesium alloy processed by indirect extrusion, showing a refined and homogeneous microstructure and achieving a very high ductility at 250 degrees C and 10(-4) s(-1). Grain boundary sliding (GBS) was concluded to be the dominant deformation mechanism based on calculations of the activation energy and interpretation of the deformation mechanism map for magnesium alloys.

Summary: This study developed novel Al clad Mg composites through continuous extrusion method, showing good metallurgical bonding between the Al shell and Mg core even without preheating of the Mg alloy. The fine-grained microstructure contributed to a significant enhancement in ultimate flexural strength (UFS) to 452 MPa. Preheating of the Mg alloy resulted in complete dynamic recrystallization (DRX) and modified texture of the Mg alloy, leading to a significant improvement in the bendability of the Al/Mg composite.

Summary: This study discusses the effect of extrusion temperatures on the microstructure, second phases particle, texture, and mechanical properties of the Mg-5Sn -1Si-0.6Ca alloy. The results show that decreasing the extrusion temperature benefits dynamic precipitation and grain refinement. The strength and plasticity of the alloy are simultaneously improved by the method of solid solution + lowtemperature extrusion.

Summary: The aim of this study is to investigate the impact of Ti on the corrosion and wear properties of Mg-5Sn-xTi (x = 0, 0.15, 0.75, 1.5 wt.%) alloys. The results showed that the wear rate decreased with an increase in Ti content, while the coefficient of friction increased with higher Ti contents. The sample with 0.75 wt.% Ti exhibited superior wear properties at lower normal forces, while the sample with 0.15 wt.% Ti showed better wear resistance at higher forces. Additionally, Ti deteriorated the corrosion features of the Mg-5Sn alloy.

Summary: Three combined extrusion techniques were used to fabricate three typical {0002} basal textures in fine-grained ZK61 magnesium alloy, and their influence on tension-compression asymmetry was evaluated. The study showed that basal texture dispersion decreased tension-compression asymmetry and achieved high-strength symmetrical ZK61 magnesium alloy successfully.

Summary: A study was conducted on the effect of rotary swaging (RS) on the microstructure and properties of a Cu-0.5%Cr-0.08%Zr alloy that was pre-extruded and pre-quenched. RS resulted in the formation of an ultrafine-grained (UFG) microstructure. This UFG structure increased the ultimate tensile strength (UTS) to 443 +/- 5 MPa and 597 +/- 9 MPa for the pre-quenched and pre-extruded alloys, respectively. Ductility was reduced after RS.

Summary: The synergistic effects of partial replacement of Al with Ca, homogenization heat treatment, and hot extrusion on the microstructure and mechanical properties of Mg-(7-x)Al-xCa magnesium alloys were studied. Homogenization resulted in eutectic constituents spheroidization and tensile ductility improvement, while hot extrusion led to fragmentation and dispersion of particles, formation of fine microstructures, and profound enhancements of tensile properties. The extruded AX43 alloy showed significantly better product of strength and ductility compared to the as-cast counterpart.

Summary: The study found that adding 0.1 wt% Ca significantly enhanced the ultimate tensile strength and elongation of the as-cast alloy. The size of DRXed grains decreased with the increase of Ca, and the best result was obtained for the Mg-5Zn-0.1Ca sample, with an ultimate tensile strength of 351 MPa and an elongation percentage of 24% for the extruded alloy.

Summary: An investigation was conducted on the effects of microstructural evolutions in the HCP a matrix (aMg) and the long-period stacking ordered phase (LPSO) of Mg97Zn1Y2 alloy on its mechanical properties. It was found that aMg acted as the soft phase and LPSO as the hard phase, and hot-extrusion improved the strength of both. With varying the extrusion ratio (R), different microstructural changes were observed, such as dynamic recrystallization and grain growth in aMg, and the development of kink bands and texture in LPSO. The strength improvement of LPSO compensated for the strength decrease of aMg at high R values, maintaining the high ultimate tensile strength of the alloy.

Summary: Transient liquid phase bonding of ZK60 magnesium alloy was conducted using aluminium foil as an interlayer, with or without graphene nanoplatelets. The addition of aluminium foil alone increased shear strength compared to adding graphene nanoplatelets with aluminium foil. The fractured surfaces showed a mixed-mode fracture and an increase in hardness due to the formation of Al12Mg17 intermetallic compound in the bonded region.
