Summary: The study shows that low stacking fault energy alloys processed by ECAP can achieve unexpected mechanical properties, with high ductility reaching up to -80% while maintaining good tensile strength. The investigation of alloy microstructure reveals a combination of deformation mechanisms, including slip and twinning, accompanied by grain boundary serration and grain fragmentation. These deformation modes trigger the unexpected mechanical properties in this alloy.

Summary: Severe warm-rolling can influence the microstructure and texture development in FCC equiatomic CoCrFeMnNi HEA, resulting in a coarser microstructure compared to cold-rolled HEA. The warm-rolled HEA exhibited a pure metal texture instead of a predominantly brass type texture, attributed to increased SFE promoting more homogeneous deformation. Additionally, warm-rolling led to a lower stored energy and coarser deformation structure, resulting in a higher recrystallization temperature and larger recrystallized grain size than cold-rolled HEA.

Summary: This study investigated the hot deformation behavior of a heat-treated Mg-12Y-1Al alloy containing long-period stacking ordered (LPSO) phase through uniaxial compression experiments. The flow stress decreased with increasing temperature and decreasing strain rate. Dynamic recrystallization (DRX) was promoted by higher temperatures. The main DRX mechanism observed was discontinuous dynamic recrystallization (DDRX), while the dense lamellar LPSO at the grain boundary hindered DDRX. The deformed microstructure showed a typical [0001]//CD texture, and its intensity decreased with increasing temperature due to multiple slip systems activation and increased DRX fraction.

Summary: The dynamic recrystallization behavior of FeCrCuMnNi high entropy alloy was investigated, and it was found that dDRX mechanism was the dominant mechanism during hot deformation, bulging was an effective mechanism for inducing new recrystallized nuclei, and grain growth was slower compared to conventional alloys. This behavior was attributed to continuous nucleation, slow diffusion, high solution hardening characteristics of high entropy alloys, and the presence of multiple phases.

Summary: Uniaxial compression experiments were conducted on as-extruded AZ31 Mg alloy at different temperatures, revealing the significant influence of temperature on grain size, proportion of DRXed grains, and texture formation. The appearance of abundant twins at 250°C promoted the formation of strong CD texture, while the transformation of DRX types from continuous to discontinuous with increasing temperature affected the texture evolution of the material.

Summary: The superplastic microstructure evolution and deformation behavior of rolled near-alpha TA32 titanium alloy were investigated. The alloy exhibited exceptional superplastic deformability with maximum elongation near 900% and flow stress sensitivity to temperature and strain rate. The flow softening process was mainly controlled by continuous dynamic recrystallization (CDRX) and dynamic recovery (DRV) mechanisms. The main deformation mechanism was the relative sliding of grains along high-angle grain boundaries (HAGBs) coordinated by dislocation motion, grain rotation, and dynamic recrystallization (DRX).

Summary: The dynamic recrystallization behavior, grain orientation, and texture formation of magnesium alloy under different deformation conditions were investigated in a thermal compression experiment. The results indicate that higher deformation temperatures lead to more complete recrystallization and uniform grain structures, while greater deformation degrees or lower strain rates result in increased recrystallization. The deformation temperature was found to be the most important factor influencing the dynamic recrystallization mechanism. Different recrystallization behaviors were observed at different temperatures, with characteristics of continuous dynamic recrystallization and rotational dynamic recrystallization.

Summary: Tantalum samples were dynamically deformed at liquid nitrogen temperature to obtain different pass samples, and comparisons were made with samples dynamically loaded at room temperature. Results showed that the LN-DPD-3pass sample had more severe fragmentation and higher proportion of random texture compared to the other samples. The uniform deformation structure and similar stored energy in the deformed grains contributed to the formation of excellent microstructure in the annealed LN-DPD-3pass samples.

Summary: Eleven-layered AZ31/AA1050 composite plates were fabricated using explosive welding. The microstructural evolution of the interfacial layers and its correlation with mechanical properties were investigated. It was found that local melting and rapid solidification resulted in the formation of reaction regions with different phases and structures. The high-hardness phases grew rapidly during annealing, and pre-existing reaction regions transformed into a specific phase. Applying pressure prevented clad delamination but not the formation of linear cracks in a specific phase.

Summary: Shear punch deformation was used to investigate the shear deformation behavior and microstructural evolution of a Mg-Y-Nd-Zr alloy at various temperatures. It was found that metastable phases may precipitate dynamically during deformation, and flow softening behavior was observed at different temperatures. The deformation mode promoted extension twinning, and twinning was observed even at high temperatures. Dynamic recrystallization occurred at 450 and 500 degrees C, with progressive lattice rotation as the mechanism. Shear flow stress was successfully modeled using constitutive equations. The rate-controlling mechanisms were determined to be dislocation glide controlled by rare earth diffusion at 25-400 degrees C and grain boundary sliding controlled by lattice diffusion at 450-500 degrees C.

Summary: The unique properties of tantalum make it highly desirable in demanding industries. Its limited availability necessitates efficient use. High efficiency can be achieved by producing layerwise heterostructured plates with a tantalum layer. This study investigates the fatigue behavior of an explosively manufactured composite with an outer tantalum layer under cyclic loading. Microcracks along the slip lines in the tantalum layer are identified as the initial damage mechanisms leading to cyclic creep. The composite plates exhibit superior fatigue strength compared to homogeneous tantalum plates.

Summary: An ultrafine-grained AZ31 Mg alloy processed through multipass equal channel angular pressing (ECAP) achieved mean grain sizes of 5 and 0.9 μm after two and four passes, respectively. Tensile testing at high temperatures revealed that the four-pass-processed alloy exhibited a superplastic elongation of 410% at 250 degrees C. The deformation behavior was studied using the Haehner criterion, showing that grain boundary sliding was the rate-controlling mechanism with a strain rate sensitivity of 0.38. The contribution of slip system to superplasticity was discussed using Schmid factors, which showed that slip activity prevalence at high strains induced texture-strengthening effect and low-angle grain boundary formation.

Summary: This study aimed to develop Fe/Al multilayered metallic/intermetallic composites produced by hot pressing under an air atmosphere. Analyses were carried out on the composite plates made up of alternatively situated sheets of AA1050 aluminum alloy and DN04 low carbon steel, which were annealed at 903 K for 2, 5, and 10 h. The samples were examined using X-Ray diffraction and scanning and transmission electron microscope equipped with an energy-dispersive X-Ray spectrometer. To correlate the structural changes with mechanical properties, microhardness measurements in near-the-interface layers were performed. All the reaction layers grew with parabolic kinetics with ii-Al5Fe2 intermetallic phase as the dominant component. After annealing for 5 and 10 hours, a thin sublayer of Theta-Al13Fe4 phase was also detected.

Summary: In this study, the authors investigated the microstructural and texture changes in CuZn30 alloy, copper, and AA1050 aluminium alloy to understand the crystal lattice rotation during shear band formation. The hat-shaped specimens were deformed at a strain rate of 560 s(-1) using a drop-hammer. The results showed a gradual shear banding process with nucleation and successive growth, rather than a sudden instability. Regardless of the initial grain orientation, a clear tendency of crystal lattice rotation was observed, leading to the formation of specific texture components. The rotation mechanism allowed slip propagation without changing the shear direction.

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: 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.
