Still, the resulting mechanical properties are intrinsically lower than selective laser melting and electron beam melting ones and, in some cases, are also lower than metal injection molding (MIM). The optimization of the printing parameters is fundamental to level off this issue and to ensure mechanical performance competitive with MIM ones. In light of this, the present work focuses, for the first time, on the optimization of the printing parameters for a Ti6Al4V alloy. The effect of three fundamental parameters, that is, layer thickness, nozzle temperature, and printing speed, is investigated, and the 3D printing process is optimized by exploiting the design of experiment and the surface response analysis techniques. The results are extremely auspicious, considering that the optimum configurations display a tensile strength of 915 MPa, which is perfectly comparable with MIM components. The statistical analysis demonstrates that nozzle temperature, printing speed, and their interaction are the most relevant parameters and the 3D printing optimum is achieved with a nozzle temperature of 160 °C and a printing speed of 15 mm s−1.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the mechanical performance and coefficient of thermal expansion (CTE) of steel–steel (S-S) CMFs at temperatures up to 1000 °C. CTE measurements indicate reduced expansion relative to bulk 316L stainless steel, with stable values between 100 and 400 °C, followed by a linear increase up to 1000 °C, indicating S-S CMF's enhanced thermal stability compared to bulk 316L stainless steel. Quasi-static compression tests show that S-S CMFs maintain excellent mechanical performance up to 600 °C, beyond which strength degradation accelerates due to thermal softening, oxidation, and plastic buckling. At 800 °C, the structural integrity of S-S CMF is significantly compromised, with lateral expansion and energy absorption capacity reduced by over 80%. Scanning electron microscopy (SEM) links the mechanical changes to microstructural evolution, including grain boundary void formation and oxidation at high temperatures. These findings provide the first comprehensive assessment of the thermomechanical behavior of S-S CMFs, bridging a critical knowledge gap and establishing their operational limits for high-temperature structural applications.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 12","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402871","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ductility and toughness, however, remain intrinsically limited because of the restricted slip systems. The slip of <c + a> dislocations, a critical <c>-axis deformation mode, can provide sufficient <c>-axis strain but needs high critical resolved shear stress to operate. This perspective highlights the nature of <c + a> dislocation—a typical limp dislocation—that leads to the difficulty in self-multiplication and relies on the existing dislocation source to proliferation. Owing to the marked difference in mobility between edge and screw components, the limp <c + a> dislocations have poor self-multiplication ability, which can be resolved by directly incorporating a high density of interfacial dislocation sources. For example, twin boundaries or phase interfaces are unique interface structures that can readily nucleate <c + a> dislocations to mediate <c>-axis plasticity.

At the same time, the nano-SiO2 generated by hydrolysis further improves the interfacial stress transfer of the composites through the interlocking mechanism. The surface roughness, O/C ratio, and compatibility with the resin matrix of the CF after sizing are significantly improved, and the interlaminar shear strength and flexural strength of the corresponding composites are increased by 53.06 and 50.89%, respectively.

To achieve the multifunctions of simultaneously programmable Poisson's ratio (PR) and coefficient of thermal expansion (CTE) in multidirections, this study proposes 3D multidirectional anisotropic metastructure (MAM) with programmable CET, PR, and Young's modulus based on the re-entrant structures and bimaterial trapezoid. The intrinsic mechanism of adjustable CTE and PR in bimaterial re-entrant structures is analyzed from the mechanical perspective. The theoretical method for Young's modulus in the y-direction is established based on Moor's theorem, and the accuracy of both the theoretical method and finite element analysis (FEA) results is verified through uniaxial compression tests. Then, the FEA results demonstrate that MAM can achieve directionally anisotropic adjustable CTE, PR, and Young's modulus by modifying the geometric parameters and material combinations. Furthermore, the mechanical responses of MAM under the thermomechanical load are investigated, achieving tunability of PR from positive to negative. This study offers a reliable reference for the design and optimization of engine components subjected to thermomechanical loads.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their outstanding electrical conductivity, conventional metal thin films often suffer from limited elasticity, typically less than 1%. Conversely, amorphous alloys offer exceptional elasticity, but their electrical resistivities do not meet industrial requirements. In this work, metallic nanolaminates composed of alternately stacked Al-based amorphous alloys and nanocrystalline Al layers as a novel kind of electrode material suitable for stretchable displays are proposed. These materials are designed to synergistically combine the mechanical properties of amorphous alloys with the electrical properties of crystalline Al and can be synthesized using currently available mass production fabrication facilities. Through in situ nanotension experiments, it is demonstrated the nanolaminates achieve a unique combination of a high elastic limit approaching 3%, large tensile elongation exceeding 17%, and excellent electrical resistivity lower than 10 μΩ cm. Deformation mechanisms in nanolaminates are further elucidated through molecular dynamics simulations.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their complexity makes utilizing them challenging and computationally intensive. Homogenization, a common method for simplifying these structures, replaces heterogeneous media with a material possessing equivalent effective properties. Despite its utility, homogenization introduces challenges, particularly the significant influence of lattice geometry on the method's accuracy and the performance of final optimized designs, which is often overlooked. This study evaluates the efficacy of biologically inspired sheet-based triply-periodic minimal surface (TPMS) lattices in homogenization-based stiffness optimization and benchmarks them against other lattice types. Using tailored probe-based metrics introduced in this study, which measure key relevant attributes such as subtopological homogeneity, load path alignment, resilience to edge effects, and achievable channel clearance, TPMS lattices like gyroids outperform strut-based lattices across all criteria. This results in significantly enhanced end-properties of 3D models optimized through numerical homogenization workflows. The findings emphasize the importance of lattice geometry in homogenization-based optimization and highlight the benefits of TPMS structures in delivering predictable performance with minimal design constraints. Additionally, the metrics developed provide a robust framework for evaluating cellular solid designs, enabling engineers to make more informed lattice design choices in comparable optimization scenarios.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402105","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These provide a greater degree of control over membrane thickness and a reduction in voltage spread between electrodes, which are evaluated in batches using a multichannel analyzer. γ-ray ionization of the pH electrodes introduces a predictable voltage drift that follows a log decay function on the day timescale; the voltage decay rate correlates with membrane thickness and can be modeled as a parallel diode–capacitor circuit. Batches of radiation-sterilized pH electrodes are tested in cell culture media and yield mean pH values within 0.05 units relative to a commercial meter (ground truth) following a single-point calibration protocol.
