Summary: Metal matrix composites reinforced with nanoparticles are becoming increasingly important in the automobile and aerospace industry due to their high performance, lightweight, and excellent mechanical strength. In this study, a nanocomposite with aluminum matrix reinforced with alumina and zirconia nanoparticles was fabricated using the stir-casting technique. The microstructural and mechanical properties of the nanocomposite were investigated and compared with those of pure rolled aluminum. The results showed that the addition of nanoparticles significantly improved the tensile strength and hardness of the nanocomposite, while slightly reducing its flexural strength.

Summary: To improve the toughness and strength of C/C-SiC composites, a carbon fiber reinforced carbon, silicon carbide, and copper alloy hybrid composite was designed and prepared via Cu-Si alloy melt infiltration at low temperature. The composite showed good mechanical properties, especially fracture toughness, due to the introduction of ductile Cu alloy in the matrix. The improved toughness was mainly attributed to the introduction of the soft Cu3Si phase.

Summary: In this study, aluminum phosphate framework (APF)/bismaleimide (BMI) hybrid composites with the double cross-linking hybrid (DCH) structures were successfully fabricated. The three-dimensional (3D) structures of APF played a critical role in enhancing the mechanical properties. The lamellar aluminum phosphate (LAP) particles were chosen to strengthen the APF/BMI composites, and it was found that they could enhance the mechanical properties and decrease the dielectric constant. This study provides helpful insights for designing higher performance inorganic/organic hybrid composites and expanding their applications.

Summary: The present study investigates the interfacial behaviors and mechanical properties of AlCoCrFeNi high-entropy alloy reinforced aluminum matrix composites (AMCs) through first-principles calculations. The stability of the HEA-reinforced AMCs is found to be strongly dependent on the chemical compositions in the interfacial regions. The interfacial energy of the Al(001)/Al20Co19Cr19Fe19Ni19(001) interfaces is calculated to vary, suggesting favorable formation of interfaces at the (100) atomic plane. Ni stabilizes the interface while Al deteriorates its stability. The HEA-reinforced AMCs show improved Young's modulus and meaningful plasticity under tension, which are related to the chemical compositions at the interfaces.

Summary: This study fabricated nano-yttrium oxyfluoride (YOF)-reinforced aluminum matrix composites (AMCs) using molten-salt-assisted stirring casting for the first time. The results showed that YOF significantly improved the mechanical properties of the Al matrix. However, with an increase in YOF content, the morphology and distribution of the Y-rich phase evolved, leading to the formation of casting defects that affected the strengthening effect of AMCs.

Summary: The presence of Ni in the Co-8Ti-11V-xNi alloys leads to a decrease in lattice misfit and changes in the size and elemental partition behavior of the gamma ' phase. Differential scanning calorimetry (DSC) was used to determine the solvus temperatures of the gamma ' phase in the different alloy compositions. Additionally, the mechanical properties, such as yield strength and ultimate strength, were found to be influenced by the Ni content, with the Co-8Ti-11V-10Ni alloy exhibiting the highest strength values.

Summary: In this study, the effects of aging treatment on the microstructure and mechanical properties of cryogenically-processed FeCoNi1.5CuB0.5Y0.2 HEAs were investigated. The results showed that increasing the aging temperature, extending the aging time, or increasing the number of aging cycles significantly improved the overall mechanical properties of the material. The optimized aging parameters resulted in a reduction in grain size, the formation of finely dispersed precipitates, and enhanced strength-ductility synergy.

Summary: Nitrogen-doped graphene quantum dots embedded in CuCo-LDH hierarchical hollow structure were synthesized to optimize the nanostructure of layered double hydroxide and alleviate agglomeration issues. The ordered multi-component structure effectively prevented aggregation and improved electron and ion transfer. The addition of nitrogen-doped graphene quantum dots further enhanced electron transmission rate and energy storage capacity, resulting in a specific capacity of 1009 F g-1 at 1 A g-1 and an energy density of 58.6 Wh kg-1 at 850 W kg-1 for the assembled CC@CuCo-LDH/NGQDs//AC device. These results demonstrate the effectiveness of the hierarchical structure and electrical conductivity in enhancing the electrochemical characteristics of asymmetric supercapacitors.

Summary: In this study, dual-phase solid solution structures with disordered and ordered FCC and BCC were achieved in Al15Fe20Co20Ni20Cr25-xNbx (x = 1, 1.5, 2, at.%) HEAs. The addition of Nb enhanced the strength of Al15Fe20Co20Ni20Cr25-xNbx HEAs and achieved a good balance between strength and strain. The Nb-containing alloys exhibited excellent oxidation resistance at temperatures of 750-1000 degrees C. The substitution of Cr by Nb improved the oxidation resistance without significantly affecting the mechanical properties, making Al15Fe20Co20Ni20Cr25-xNbx HEAs promising candidates for multi-component superalloys.
