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: We investigated the microstructure, mechanical, and corrosion properties of an AZ61 alloy extruded using the KoBo method. The KoBo method enables extrusion of AZ61 without preheating and results in significant microstructure refinement. However, this study found that it did not enhance the strength or corrosion resistance of the AZ61 alloy. The continuously precipitated Mg17Al12 phase along the grain boundaries was identified as the main factor affecting the alloy's properties.

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 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: The corrosion behaviors and mechanism of Mg-xZn-0.5Er (x = 0.5, 2.0, 3.0 and 4.0, in wt.%) alloys were investigated. The potential difference between the second phase and matrix was determined by the type and size of the second phases. The dominated nano-scale W-phase on the matrix induced sharp local pitting corrosion, while an increase in the volume fraction of the coarse W-phase or I-phase resulted in preferential corrosion around them, leading to obvious uniform corrosion and an accelerated corrosion rate.

Summary: This study investigated the effect of varying Zn additions on the corrosion resistance of wrought Mg-5Al alloys, identifying three secondary phases that contribute to changes in the corrosion behavior. While short periods of immersion are characterized by pitting corrosion, long periods lead to the formation of a protective layer and filiform corrosion in alloys with higher Zn content. The micro-galvanic effects continue to play a crucial role in deteriorating corrosion resistance in alloys with relatively high Zn content, depending on the behavior of the cathodic particles and their total number on the alloy's surface.

Summary: A Mg-3Y-2Gd-1Nd-0.4Zr alloy with low rare earth content was developed and prepared by sand casting with a differential pressure casting system. The aged alloy exhibited excellent comprehensive mechanical properties due to the formation of fine dense plate-shaped beta' precipitates during aging. This new developed alloy showed better properties compared to commercial WE43 alloy for fabricating large complex thin-walled components.

Summary: In this study, the texture evolution of two Mg materials during tension is investigated. It is found that pure Mg and Mg-15Gd alloy exhibit different deformation modes, with pure Mg showing a dominant prismatic slip and Mg-15Gd alloy showing a complex behavior of twinning and multiple slips. The critical resolved shear stress ratios between non-basal slip and basal slip are lower for Mg-15Gd alloy compared to pure Mg.

Summary: The effects of adding different amounts of AlN nanoparticles on the microstructural evolution and strengthening mechanisms of Mg-3Sn-1Ca based alloys were investigated. It was observed that increasing the amount of AlN nanoparticles led to a significant decrease in grain size. The presence of AlN nanoparticles refined the primary crystal phases and provided more nucleation sites for the formation of magnesium. Additionally, the nanoparticles restricted grain growth during solidification. The addition of AlN nanoparticles resulted in improved tensile properties and hardness at both room temperature and high temperature.

Summary: The influence of different Al contents on the microstructural evolution and creep resistance of Mg2.85Nd-0.92Gd-0.41Zr-0.29Zn alloy was investigated. It was found that the additions of 0.5 wt% and 1 wt% Al significantly decreased the creep rate, while the addition of 2 wt% Al led to decreased creep properties. Microstructural analysis revealed changes in grain coarsening or refinement and phase transformation with different Al contents. Creep resistance was enhanced by the additions of 0.5 wt% and 1 wt% Al, but deteriorated by the addition of 2 wt% Al due to the detrimental microstructure.

Summary: This study focuses on DieMag633, a cast Mg-Al-Ba-Ca alloy. Brittle interdendritic phases strongly affect crack initiation and propagation under quasi-static and fatigue loading. The material has low failure resistance under tensile loading. Selected fatigue loading sequences were used to investigate crack propagation. DieMag633 in this study contains significant shrinkage cavities and pores that have irregular distribution. The cracking is mainly influenced by Ba- and Ca-rich phases, rather than the Mg-matrix. Transgranular cracking is observed mainly in the compact Ba-rich phase and the lamellar Ca-rich phase.

Summary: The application of magnesium flat products is affected by the limited formability at room temperature and the anisotropy of the mechanical properties, which is mainly caused by the underlying hexagonal crystal structure of magnesium and the development of strong crystallographic textures during massive forming processes. This study focuses on the influence of the manufacturing process on the microstructure and texture evolution of flat products made of conventional magnesium alloy AZ31, and discusses the effects on mechanical properties and formability.

Summary: This study further improved the mechanical properties and thermal conductivity of Mg-Zn-La/Ce alloys through aging treatment, achieving good comprehensive performance. The addition of La/Ce forms a ternary tau 1 phase that reduces the supersaturation of the Mg matrix and has a positive effect on thermal conductivity. Precipitation has two opposite effects on thermal conductivity, reducing supersaturation but hindering the free movement of electrons and phonons.

Summary: Heterogeneous TiC/AZ61 nanocomposites were fabricated to enhance both the strength and ductility of Mg matrix composites. The proportion of TiC-rich fine grain (FG) zones and TiC-rare coarse grain (CG) bands could be adjusted by changing the mechanical ball milling time. The composites achieved excellent mechanical properties with a volume fraction of 25% CG bands after 20 h of ball milling, which was attributed to the presence of geometrically necessary dislocations (GNDs) in the CG bands.

Summary: This study investigates the creep behavior and microstructural evolution of sand-cast Mg-14Gd-0.4Zr alloy using compressive creep tests. The results show that the coherent distribution of beta' and beta' (F) phases effectively impedes dislocation movement and enhances creep resistance. However, with increasing creep time, the fine precipitate chains coarsen and transform into different phases, leading to stress concentration and increased creep strain.
