Summary: This study investigated the mechanical and tribological properties of niobium-alumina composites obtained by spark plasma sintering. The addition of niobium improved fracture toughness and wear resistance, leading to higher wear resistance against steel counterbody. Furthermore, alumina exhibited higher wear rate when sliding against Al2O3 counterbody at higher loads. Wear regime maps allowed the visualization of improved wear resistance of niobium-alumina composites.

Summary: This study investigated the toughening mechanism of iPP/EPR/SiO2 composites at low temperatures. It was found that the synergistic regulation of T-bd by EPR and SiO2, as well as the increase in silica content, could effectively enhance the low-temperature toughness of the composites. Additionally, the proposed toughening mechanism involved the increased internal friction loss induced by the expanded phase interfacial area between EPR and iPP matrix, leading to high-elastic deformation and ductile fracture behavior in the composite at low temperatures.

Summary: In this study, WBx films were deposited at different substrate bias voltages to regulate their microstructure and optimize their mechanical and wear resistance properties. Increasing the bias voltage reduced the B content and improved hardness, while also increasing the relative content of the W2B toughening phase and enhancing toughness. The film grown at -120 V achieved dual optimization of hardness and toughness, resulting in super wear resistance.

Summary: Exploring routes for the effective use of recycled carbon fibres (rCFs) is critical to improve the fracture toughness of carbon fibre/epoxy composites. This study demonstrated the potential of using rCFs with PPS fibres for interlayer toughening, resulting in significant enhancements in the interlaminar fracture properties. The main toughening mechanisms were found to be fiber bridging for rCF/PPS mats.

Summary: Nanostructured W-Cu-Cr composites with exceptionally high hardness were fabricated in this study, showing nonmonotonic variation of wear resistance with hardness. The appropriate content of Cr facilitated the formation of a stable protective film, leading to higher microhardness at the worn surface and reduced wear rate. Excessive addition of Cr, however, may deteriorate wear resistance despite higher hardness.

Summary: In this work, dense and light B4C-(Ti0.9Cr0.1)B-2 composites with excellent mechanical properties were successfully designed and reactively densified from boron, TiC, and Cr3C2 powder mixtures by spark plasma sintering. The as-obtained B4C-(Ti0.9Cr0.1)B-2 composite exhibited enhanced hardness, specific hardness, flexural strength, and fracture toughness compared to the counterparts. The higher fracture toughness of the B4C-(Ti0.9Cr0.1)B-2 composite was mainly attributed to their larger initial fracture toughness and compressive stress toughening.

Summary: The study found that adding Cr/Mo significantly improved the corrosion resistance and wear resistance of Fe-Mn-Al-C lightweight steel. This improvement can be attributed to the formation of protective oxide film in the solution, reducing the generation of harmful oxides and increasing the compactness and charge transfer resistance of the material.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
