Summary: The study found that non-inert casting atmospheres can significantly improve the glass forming ability of P-containing Fe-based BMGs, while not affecting their thermal and magnetic properties. The surface composition of the BMGs varied greatly with different casting atmospheres, while the bulk composition remained unchanged. The enhancement of GFA by non-inert casting atmospheres was mainly attributed to the increased surface tension resulting from the elimination of oxygen element and the alloying effect of nitrogen element in the casting atmospheres.

Summary: In this study, a simple method was used to quantify the castability and glass-forming ability (GFA) of two SIM card slots with different designs, as well as at different casting temperatures. It was found that the Zr55Cu30Ni5Al10 (Zr55) alloy has a wider optimal casting temperature range compared to the Zr52.5Cu25Ni9.5Al7Ti6 (Zr52.5) alloy, indicating better GFA of Zr55. However, within the optimal casting temperature range, the castability of Zr52.5 was significantly better than that of Zr55 due to its lower melting point, poorer wettability to the copper mold, and higher optimal casting temperature. These findings provide guidance for the production of Zr-based bulk metallic glass components.

Summary: In the design and development of next-generation Ni-based superalloys, the addition of refractory impurity elements such as X = Mo or W atoms has been found to enhance bonding strengthening and structural stability of gamma and gamma ' phases. The study also suggests that larger atomic size X = W impurities may increase the precipitate volume fraction, leading to improved mechanical strength, while X = Mo atoms contribute to relatively strong bonding interactions within both gamma and gamma ' phases. Additionally, the slow-diffusing X = W atoms exhibit better bonding stability in the gamma matrix and at the gamma/gamma ' interface, resulting in a significant delay in precipitate coarsening.

Summary: The atomic size of alloying elements is the primary factor affecting the strengthening of Ni-based superalloys. This study investigates the influence of Hf element addition and its co-additions with Mo(W) elements on the microstructural and mechanical properties of model Ni80Al15Hf5 and Ni80Al15Hf2.5Mo(W)2.5 superalloys. It is concluded that replacing a portion of Hf addition with Mo(W) can reduce the participation tendency of Hf and Mo(W) elements, and the co-addition of Hf and W leads to better mechanical strength.

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: 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.
