Summary: The study systematically investigated the localized corrosion behavior and microstructure of an Al-2.23Cu-0.96Li (wt%) alloy using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It was found that the GPB zones in the alloy do not significantly affect the overall propagation direction of crystallographic corrosion, but are closely related to the formation of nanoscale localized corrosion morphology in the crystallographic corrosion.

Summary: The research focused on the design and corrosion resistance of five single-phase Ni-Fe-Cr-Mo-W-X multi principal element alloys, which were heat treated at 800 degrees C to increase hardness and strength through the precipitation of secondary phases. After aging, the MPEA with Al showed the most significant increase in hardness, about 90%. Electron microscopy revealed the presence of multiple phases in the aged MPEAs that differed from those predicted at thermodynamic equilibrium.

Summary: Only a few high strength aluminum alloys can be processed using Laser Powder Bed Fusion due to the occurrence of hot cracks during solidification. The addition of zirconium and scandium in aluminum-magnesium alloys has been proven effective in suppressing solidification cracking and improving strength. Therefore, it is necessary to focus on novel aluminum alloys with enhanced processability and low scandium content.

Summary: The effects of annealing on the microstructure of pure Ni fabricated by laser powder bed fusion (LPBF) were studied using Gaussian and flat-top beam profiles. The initial as-fabricated samples had a predominantly arrangement of statistically stored dislocations. The as-annealed specimens showed minimal static recrystallization, despite the high dislocation density in the as-fabricated samples. However, both types of specimens showed static recovery, with the Gaussian-LPBF-derived specimens exhibiting more prominent misorientation of dislocation boundaries.

Summary: Developing technologies for efficient, safe, and economical hydrogen storage is crucial for the application of hydrogen. V-based body-centered cubic (BCC) alloys are a promising material with high theoretical storage capacity, but their practical applications are hindered by the high cost of V. In this work, a novel V alloy with only 5 at% V was developed using suction casting method, achieving a dehydriding capacity of up to 2.9 wt% H. The microstructural control and de-/hydrogenation mechanism of the developed alloys were systematically investigated. The work provides a significant guide for designing new-generation hydrogen storage alloys with low cost and excellent hydrogen storage performance.

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.
