Summary: Low-cost Mg-1Mn-0.5Al (MA10) alloys with good comprehensive strength and ductility have been developed as potential substitutes for commercial AZ31 alloys. The rollability of MA10 alloy sheets in terms of edge cracking behavior was improved by multi-pass online heating rolling at different temperatures. The improvement can be attributed to the more uniform microstructure, higher degree of recrystallization, more homogeneous strain distribution, and increased activation of non-basal slips at the edge.

Summary: This paper investigates the corrosion behavior of Mg-5.7Gd-1.9Ag alloy sheets in a salt solution. The results show that the rolled sheets exhibit better corrosion resistance compared to the as-cast sheets. Aging treatment decreases corrosion resistance, but it still remains higher than that of the as-cast sheets. The migration of corrosion is mainly influenced by the evolution of second phases rather than grain size and texture.

Summary: In this study, the edge cracking behavior of the Mg-2Zn-1.5Mn alloy and the initiation and propagation of cracks were investigated through hot-rolling and in-situ tensile tests. The results reveal that the edge cracks are most likely to occur in the rolling direction and normal direction planes, and they become more severe with increasing reduction. The cracks mainly originate in the fine recrystallized grain areas and the junction of recrystallized grains and sub-grains with hard orientation.

Summary: The microstructure and texture development of Al-Cu-Mg alloy with a high Cu/Mg ratio were studied during homogenisation and hot rolling. It was found that large particles inhibited the activation of certain slip systems, resulting in a decrease in texture intensity. With an increase in reduction, different slip systems were activated and different slip traces appeared. The decrease in the spacing of slip traces helped enhance the intensities of specific texture types.

Summary: The thermal effect has a negative impact on the strength and fracture properties of rocks. Under conventional heating paths, the P-wave velocity, peak load, and fracture toughness of rocks decrease with increasing temperature. Under complex heating paths, maintaining a constant temperature of 200 degrees C does not weaken the mechanical properties of the rocks, while maintaining a constant temperature of 400 degrees C results in significant reduction.

Summary: We report the formation of an unusual texture on the sheet-surface of a rolled Mg-3Al-0.4Mn alloy, where a typical basal texture is formed at the center of the sheet and an unusual texture with vertical tiling is observed at the sheet-surface. The surface promotes prismatic slips and dynamic recrystallization, leading to a high fraction of fine basal-textured grains and a small fraction of off-basal-textured grains. In contrast, the center preserves a relatively high fraction of deformed grains, promoting the growth of basal-textured grains and the formation of the typical basal texture.

Summary: This paper investigates the effect of artificial aging on the mechanical properties and microstructures of cryogenic rolled Al-Mg-Si sheet. It was found that while the hardness and yield strength of cryogenic rolled alloys decrease at the early aging stage, those of room temperature rolled alloys increase. Additionally, cryogenic rolled alloys exhibit substructures and lower degree of recrystallization compared to room temperature rolled alloys. A proposed precipitation mechanism and model explain the difference in strength and precipitation strengthening between cryogenic rolled alloys and room temperature rolled alloys.

Summary: Especially in the automotive sector, high-strength sheet materials often exhibit sensitivity to edge cracks during the manufacturing process. Various edge crack testing methods have been developed to assess this sensitivity under different stress conditions. Only the hole expansion test according to ISO 16630 has been standardized, but there are some gaps in the process description and modifications may be required. Additionally, the results of the test can be influenced by the machine operator.

Summary: This paper reports the application of cold-sample rolling (CSR) processing in a Mg-6Al-1Zn alloy sheet, which resulted in a high fraction of double twins and a substantial texture-weakening effect. Compared to high-temperature rolling (HTR) processing, CSR processing induced a relatively higher texture-weakening effect. The results indicate that twinning-mediated static recrystallization is essential for texture weakening in Al-concentrated Mg-alloy sheets.

Summary: The thermal conductivity of magnesium alloys deteriorates with the improvement of mechanical properties such as grain refinement and alloying. However, a novel low-alloy Mg-2Ga-0.6Ca-0.6Ce alloy shows a surprisingly good combination of high strength and high thermal conductivity compared to other samples. The addition of Ca and Ce significantly improves both tensile properties and thermal conductivity by reducing solute Ga atoms in alpha-Mg and strengthening the alloy through grain boundary and dislocation strengthening.

Summary: The microstructure, texture, and mechanical behavior of ZK60 magnesium alloys were investigated through hot rolling and sheet extrusion techniques. It was found that the extrusion process improved tensile properties, but did not affect deformability in shear punch test (SPT). This was attributed to the hindering effect of Mg4Zn7 particles on the glide of pyramidal dislocations in SPT, despite the positive effect of grain refinement on ductility.

Summary: The MgAl Layered double hydroxides (LDHs)/graphene oxide (GO) composite film was synthesized in situ on the micro-arc oxidation (MAO) film of AZ31 magnesium alloy using hydrothermal chemical conversion method. The growth behavior and corrosion properties of the composite film were investigated. The results showed that the composition and morphology of the composite film changed gradually with the extended hydrothermal treatment time, utilizing the self-dissolved cation in the MAO film as the LDHs source. The MAO/LG-12 h coating exhibited higher corrosion resistance (1.28 x 10-9 A/cm2) compared to the MAO coating (8.49 x 10-6 A/cm2), thanks to the synergistic effect of GO and LDHs.

Summary: In this study, rutile-type molybdenum dioxide (R-MoO2) was synthesized and used as the cathode materials in both Mg-ion batteries (MIBs) and hybrid Mg/Li-ion batteries (MLIBs). The electrochemical performance of MLIBs was greatly enhanced compared to MIBs, and the energy storage mechanism involved Mg2+ intercalation in MIBs and Mg2+/Li+ co-intercalation in MLIBs. This research further explores the energy storage mechanism of MLIBs and lays the theoretical foundation for the development of high-performance cathode materials.

Summary: The low specific capacity and Mg non-affinity of graphite limit the energy density of ion rechargeable batteries. In this study, we identify that the monolayer C12-3-3 in sp2-sp3 carbon hybridization with high Li/Mg affinity is a suitable anode material for Li-ion batteries and Mg-ion batteries. The monolayer C12-3-3 exhibits high specific capacities for Li and Mg, surpassing most previous anodes. The 2D carbon material of C12-3-3 also demonstrates rapid diffusion kinetics, making it a promising choice for high-capacity and high-rate performance batteries.

Summary: A highly homogeneous fine-grained Mg-3Al-1Zn (AZ31) alloy was successfully fabricated using a simple extrusion method called pre-die forging extrusion (PFE). The strain induced by the pre-forging process led to crystal defects and a higher driving force for dynamic recrystallization. By using PFE for 60 s at 300 degrees C (300-60 s), the grain size of the AZ31 alloy was significantly refined to 1.74 mu m. The 300-60 s samples exhibited excellent mechanical properties with a tensile yield strength of 305 MPa and an elongation of 27%. The improvement in the mechanical properties of the PFE samples is mainly attributed to the grain refinement mechanism. This study provides an experimental basis for determining the appropriate temperature to refine the grains during extrusion.

Summary: In the pursuit of high-energy-density lithium-ion batteries, the safety issues of batteries have become apparent. To address this, a new flame-retardant separator has been developed to enhance the safety performance of lithium-ion batteries. The flame-retardant separator utilizes nitrogen-phosphorus synergistic effect to dilute noncombustible gas and rapidly suppress thermal runaway. Experimental results show that the developed separator exhibits negligible shrinkage at 200 degrees C and extinguishes flames in just 0.54 seconds, surpassing commercial separators. Moreover, pouch cells have been assembled to validate the safety performance of PVDF-HFP/MPP separators.

Summary: The study investigates the influence of Ca on the thermal expansion and mechanical properties of Mg. It is found that alloying Ca can significantly decrease the coefficient of thermal expansion (CTE) and increase the strength of Mg. The low CTE and high compressive yield strength achieved in Mg-Ca alloys are closely related to the increased precipitation of Mg2Ca phase, which has high melting point, elastic/shear moduli and low CTE. The increased fraction of the eutectic lamellar structure consisting of Mg2Ca and a-Mg also contributes to the noticeable increase of strength in the as-cast Mg-Ca alloys.

Summary: This study aims to explore the relationship between the texture and tensile properties of the AZ31 Mg alloy using machine learning. Texture characteristic parameters such as maximum pole intensity (Imax), texture dispersion (D), and texture directivities along the longitudinal direction (PLD) and transverse direction (PTD) are extracted from the (0002) pole figures. An artificial neural network (ANN) model is constructed and trained using data from literature to describe the relationship between texture characteristics and tensile properties. The ANN model shows good predictive performance in yield strength and elongation of the AZ31 Mg alloy when applied to new cases. The correlations between texture characteristics and tensile properties are analyzed based on the ANN-predicted results.

Summary: Due to their high safety, low cost, and environmental friendliness, aqueous rechargeable Mg-ion batteries (ARMIBs) have attracted extensive attention as future energy storage systems. However, the poor migration kinetics of Mg2+ during intercalation/extraction still limits the development of suitable cathode materials. In this study, a layered buserite Mg-Mn oxide (MMO) with a large interlayer space and low-crystalline structure was found to enhance the Mg2+ migration kinetics. The MMO cathode exhibited high Mg storage capacity, excellent rate capability, and fast Mg2+ migration in the aqueous electrolyte.
