Summary: The addition of Ce element can significantly improve the microstructure of ZK60 alloy, reducing grain size and increasing the total fraction of precipitates, thereby enhancing the mechanical properties of the alloy. Ce element can also improve the wear resistance of the alloy, enhancing wear resistance under low load conditions and providing a protective oxide layer under high load conditions. However, under severe oxidation conditions, the microstructural evolutions caused by Ce addition do not contribute to the enhancement of wear resistance.

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: Rotating backward extrusion (RBE) is a severe plastic deformation (SPD) method used to produce cylindrical components with very large strain by a single pass. The cup-shaped sample formed by RBE exhibited a typical gradient microstructure, with the average grain size decreasing along the radial direction due to different strains and strain rates in different regions. The center region showed the highest deformation and the edge region exhibited the lowest deformation in the RBEed sample.

Summary: Mg-Zn-Zr (ZK) alloys have high mechanical strength, but are susceptible to hot cracking due to the formation of low melting point precipitates. Adding rare earths can improve the alloy's performance. Ce-base mischmetal addition can enhance hot rolling behavior, refine grain size, and improve mechanical properties of ZK60 alloy.

Summary: This study develops a new criterion to predict the solid-state welding quality of magnesium alloy during porthole die extrusion. The criterion considers the mechanism of interfacial void shrinkage, including plastic deformation and atomic diffusion. The criterion is validated through experiments and numerical simulations, showing that the bonding strength increases with higher billet temperature and lower extrusion speed. The developed criterion is more reliable compared to existing criteria in predicting magnesium alloy extrusion-welding quality.

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.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
