Summary: This study reports the fabrication of Mg-3Y-xSiCp (x = 0, 1, 3, 5 wt%) composites by stir casting with ultrasonic vibration followed by extrusion. The addition of SiCp promotes grain refinement and inhibits dynamic recrystallization, resulting in smaller grain size and decreased recrystallization proportion. The composites exhibit higher ultimate tensile strength and yield strength due to the combination of grain refinement and dislocation strengthening.

Summary: The effects of bimodal microstructure on the tensile properties and fracture toughness of Mg-9Gd-4Y-0.5Zr alloys were investigated. The results showed that the bimodal grain structure exhibited better yield strength and plane strain fracture toughness compared to the fully dynamic recrystallized (DRXed) microstructure. The bimodal grain structure had a higher tensile strength due to hetero-deformation induced (HDI) strengthening effect and strong basal texture. In addition, it had a stronger strain hardening capacity and larger hardened region, leading to improved fracture toughness.

Summary: This study investigated the effect of Mg2Si amount on the properties of Al-Mg2Si as-cast composites. Composites with different amounts of Mg2Si were fabricated and analyzed for fluidity, viscosity, porosity formation, and tensile properties. The results showed that increasing the amount of Mg2Si led to irregular morphology and increased size of primary Mg2Si, decreased fluidity, increased viscosity, and increased porosity. The composite with 15% Mg2Si exhibited better tensile properties and higher quality index compared to the others, and the fracture surface of composites with lower Mg2Si amount showed more ductile mode.

Summary: This work focuses on improving the strength, ductility, and elastic modulus of magnesium matrix composites (MMCs) by reinforcing Mg-3Al-1Zn composites with micron-sized Ti particles through powder metallurgy. The addition of Ti particles increases the yield strength, elongation, and elastic modulus. The formation of TiAl phase and MgO layer at the interface enhances the interfacial bonding between Ti particles and the Mg matrix. The composite with 9Ti/Mg-3Al-1Zn composition exhibits the best mechanical properties with high strength and improved ductility due to grain refinement and collaborative deformation of Ti particles.

Summary: The oxidation kinetics and microstructural evolution of Cf/ZrB2-SiC composites are studied, and an empirical model is established for predicting the oxidation behavior. Three oxidation mechanisms of carbon phase controlled by reaction and diffusion kinetics, categorized as uniform, non-uniform, and superficial oxidation, are identified based on morphology observations and in-situ tensile responses. The relationship between fracture modes and internal fiber microstructures suggests that the toughening mechanism transition induced by oxidative damage is the structural origin of the fracture mode transition.

Summary: This study aims to analyze the effects of temperature and strain rate on the tensile properties of long glass fiber-reinforced polypropylene composites. The experimental results show that both tensile strength and tensile fracture stress increase significantly at a temperature of 25°C and strain rates of 10(-4), 10(-3), 10(-2), and 10(-1) s(-1). On the other hand, these properties decrease significantly when the strain rate is fixed at 10(-4) while temperatures range from -25°C to 75°C. Cracks appear on the fracture surface at lower temperatures, while matrix softening occurs at higher temperatures. These findings emphasize the significant influence of both strain rate and temperature on high fiber content long glass fiber-reinforced polypropylene composites.

Summary: TiP/VW94 composites were prepared using semi-solid stirring assisted ultrasonic vibration followed by hot extrusion. The addition of Ti particles promoted the precipitation of lamellar long period stacking ordered structure (LPSO) and inhibited the precipitation of block-shaped LPSO during heat treatment. The tensile properties of TiP/VW94 composites were enhanced by load transfer, grain refinement, dislocation strengthening, and the presence of appropriate content and size of lamellar LPSO and RE-rich phase.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
