Abstract ：
3D-Kagome lattice sandwich panels are mainly composed of upper and lower panels and a series of symmetrically and periodically arranged lattices, known for their excellent high specific stiffness, high specific strength, and energy absorption capacity. The inherent geometrical symmetry of the 3D-Kagome lattice plays a crucial role in achieving superior mechanical stability and load distribution efficiency. This structural symmetry enhances the uniformity of stress distribution, making it highly suitable for automotive vibration suppression, such as battery protection for electric vehicles. In this study, a polyurethane foam-filled, symmetry-enhanced 3D-Kagome sandwich panel is designed following an optimization of the lattice structure. A novel fabrication method combining precision wire-cutting, interlocking core assembly, and in situ foam filling is employed to ensure a high degree of integration and manufacturability of the composite structure. Its mechanical properties and energy absorption characteristics are systematically evaluated through a series of experimental tests, including quasi-static compression, three-point bending, and low-speed impact. The study analyzes the effects of core height on the structural stiffness, strength, and energy absorption capacity under varying loads, elucidating the failure mechanisms inherent to the symmetrical lattice sandwich configurations. The results show that the foam-filled sandwich panels exhibit significant improvements in mechanical performance compared to the unfilled ones. Specifically, the panels with core heights of 15 mm, 20 mm, and 25 mm demonstrate increases in bending stiffness of 47.3%, 53.5%, and 51.3%, respectively, along with corresponding increases in bending strength of 45.5%, 53.1%, and 50.9%. The experimental findings provide a fundamental understanding of foam-filled lattice sandwich structures, offering insights into their structural optimization for lightweight energy-absorbing applications. This study establishes a foundation for the development of advanced crash-resistant materials for automotive, aerospace, and protective engineering applications. This work highlights the structural advantages and crashworthiness potential of foam-filled Kagome sandwich panels, providing a promising foundation for their application in electric vehicle battery enclosures, aerospace impact shields, and advanced protective systems.

Abstract ：
Left ventricular assist devices (LVADs) provide an effective artificial support treatment for patients with advanced-stage heart failure. To enhance the LVAD performance and optimize its internal flow field, different blade trailing edge treatment techniques are employed. This study mainly investigates the effects of two methods: bladelet and blade trimming. The effectiveness of these two techniques in LVADs has not been thoroughly evaluated in previous research. The flow field distribution and hydraulic performance of different impellers are obtained by computational fluid dynamics (CFD) simulations. The results reveal that bladelets can significantly weaken the hydraulic performance of LVADs. However, the appropriate bladelet parameters can reduce the hemolysis value and improve hemocompatibility. Similarly, suitable blade trimming parameters can optimize the hemocompatibility of LVADs. Nevertheless, excessive blade trimming can increase hemolysis. Lastly, blade trimming has minimal impact on the hydraulic performance of LVADs. © 2025 The Author(s)

Abstract ：
Rapid and safe vascular anastomosis can improve the success rate of surgical procedures and further promote wound healing in patients. Vascular anastomosis connectors (VACs) hold significant potential for facilitating rapid and safe anastomosis. In this study, polylactic acid (PLA) and polycarbonate (PC-ISO) are selected as the materials to prepare VACs. The biomedical properties of the two materials are evaluated, and based on these results, conical thread snap-type VACs are designed. The anastomotic performance of the VACs is assessed using an extracorporeal mock circulation system (MCS). The results show that both PLA and PC-ISO degrade slowly in a simulated body fluid environment, with the sample weight change remaining within 0.37 wt%. Moreover, both materials exhibit good blood compatibility, showing no potential cytotoxicity. In addition, cells adhere well to their surfaces for proliferation, indicating strong biocompatibility. The in vitro MCS simulation tests reveal that both types of VACs can achieve rapid vascular anastomosis, meeting the performance requirements for tensile strength and leak resistance.

Abstract ：
This study addresses the enhancement of thermal stability of zinc alloys, which commonly experience reduced mechanical performance beyond 100 degrees C. The 304 stainless steel wires (SSWs) were utilized to fabricate a 3D porous metal rubber (MR) skeleton, facilitating the infusion of molten zinc alloys (ZA8) via squeeze casting to prepare MR/ZA8 composites. The impact of varying SSW volume fractions on the static compression creep (SCC) behavior of the MR/ZA8 composites at 250 degrees C was investigated, while exploring their SCC failure mechanisms. Energy dispersive spectrometer was used to analyze the MR/ZA8 composites both before and after the creep experiments. Findings revealed that in comparison to ZA8, MR/ZA8 composites exhibited notably lower SCC strain, diminishing with the increased SSW volume fraction. Under the applied stresses of 12 MPa, 17 MPa and 20.4 MPa, the steady-state SCC rate of MR/ZA8 composites experienced a reduction of 1 order of magnitude compared to ZA8. The apparent stress exponent n value ranged from 3.37 to 4.84, indicating a SCC mechanism dominated by dislocation climb within the two materials. The elemental composition of the MR/ZA8 composites remained largely unchanged, and the MR skeleton in the MR/ZA8 did not undergo oxidation.

Abstract ：
K417G superalloy is widely applied in gas turbine components such as blades, vanes, and nozzles. In this work, the oxidation behavior and mechanism of K417G alloy prepared by wide-gap brazing were investigated in air at 800, 900, 1000, and 1100 °C. Microstructures of the bonded joints differ in the wide-gap braze region (WGBR) and base metal (BM). The surface and cross-sectional morphology, composition, and structure of specimens were analyzed by XRD, SEM, and EDS after oxidation tests. The experimental data demonstrate that the WGBR (wide-gap brazed region) exhibits markedly superior oxidation resistance compared to the BM (base material) under elevated-temperature conditions exceeding 1000 °C. This performance disparity is quantitatively validated by oxidation kinetics analysis, where the weight gain curve of the WGBR demonstrates parabolic oxidation kinetics, as evidenced by its significantly lower parabolic rate constant relative to the BM. The oxide layers of the BM and WGBR are similar after oxidation at high temperatures of 800–900 °C, and they consist of an outermost layer of NiO, a middle mixed layer of Cr2O3, and an innermost layer of dendritic Al2O3. However, when the temperature is between 1000 and 1100 °C, the NiO on the surface of the BM spalls of due to thermal expansion coefficient mismatch in coarse-grained regions, resulting in oxidation mainly divided into outer layer Cr2O3 and inner layer Al2O3 and TiO2. Under high-temperature oxidation conditions (1000–1100 °C), a structural transition occurs in the oxide scale of the BM, with the underlying mechanism attributable to grain-coarsening-induced oxide scale destabilization. Specifically, the coarse-grained structure of the BM (characteristic grain size exceeding 50 μm) is exhibited. Therefore, the WGBR demonstrates outstanding oxidation resistance, as evidenced by the formation of a continuous Al2O3 scale with parabolic rate constants of about 1.38 × 10−3 mg2·cm−4·min−1 at 1100 °C. © 2025 by the authors.

Abstract ：
This study presents a new surface strengthening technique (cold upsetting manufacturing process) for engine valve seating face (VSF). The properties of the Ni30 superalloy VSF were characterized before and after cold upsetting. Compared to the solution-aging treatment (SAT) valve, the solution-cold upsetting-aging treatment (SCUAT) valve hardness was increased by 60 HV0.2. SCUAT valves exhibited higher internal dislocation degrees and local misorientation than SAT valves. Bench-top wear tests at 650 degrees C and 750 degrees C were conducted. The valve wear loss at 650 degrees C was higher than that at 750 degrees C. SCUAT valves show better wear resistance, with a total wear loss reduction up to 26.76 %. The SCUAT valve-seat insert contact pair wear mechanisms are adhesive and fatigue wear.

Abstract ：
Textured surfaces have been widely applied in the field of engineering for friction reduction, but research on the effects of different texture design parameters on the wear and fatigue resistance of bearing steel remains insufficiently explored. In order to improve the anti-wear and anti-fatigue performance and prolong the service life of bearing steel, surface texturing technology was applied to fabricate textured GCr15 bearing steel materials. In this work, micro-groove surface texture was designed by hydrodynamic theory, then, it was fabricated on the GCr15 bearing steel surface using nanosecond laser processing. The depths (15 mu m, 30 mu m), spacing (100 mu m, 200 mu m, 300 mu m), and friction angles (30 degrees, 60 degrees, 90 degrees) of micro groove were selected as the primary parameters for micro groove fabrication. The friction and wear tests and rolling contact fatigue (RCF) tests were conducted to investigate the lubrication tribological properties. The results indicated that micro-groove spacing of 300 mu m significantly reduces the coefficient of friction (CoF), depth of 30 mu m produces a higher hydrodynamic pressure, and friction angle of 60 degrees has a lower CoF value. Compared to the untextured samples, the RCF life of micro-groove surface texture sample is improved, and the median RCF life is increased by 36.5%. And it could be attributed to the dispersion effect of micro-groove surface texture on stress concentration. The findings indicate that a well-designed micro-groove structure can enhance the fluid dynamic pressure lubrication effect to a certain degree. In comparison to smooth surface specimens, those with micro-grooves exhibit reduced friction.

Abstract ：
As a nickel -based alloy, GH4169 has the properties of excellent corrosion resistance, high temperature oxidation resistance and high creep resistance. In this paper, the compression creep behaviors of cylinder entangled wire materials (CEWMs) made from metal wires (GH4169 nickel -based alloy, 304 stainless steel) were investigated at elevated temperatures (from 400 degrees C to 500 degrees C). The performance degradation of the two materials was evaluated by the variation amplitude of four mechanical properties parameters and material characterization methods. The results indicated that both of 304 CEWMs and GH4169 CEWMs suffered a significant performance degradation at elevated temperatures, and both of the two CEWMs showed a much serious performance degradation above 450 degrees C (tempering temperature). Compared to the 304 CEWMs at the tested temperatures, the GH4169 CEWMs obtained better creep resistance. It is therefore concluded that the GH4169 CEWM is an excellent material that can replace the commonly used 304 CEWM at elevated temperature work conditions.
