The initial seed particle formation and growth rate are harmonized to yield monodisperse silica particles up to 2 μm (and potentially beyond) in a single step. Therefore, a diluted TEOS solution is slowly added to the ethanolic aqueous ammonia solution at 0 °C in a first phase to build seed particles. After a waiting time, a systematic particle growth is achieved by dosing ethanolic TEOS at 40 °C. The particle diameter scales with the cubic root of the amount of added TEOS. A fast etching procedure (3.5 min at 95 °C) of the received Stöber particles using 0.025 M NaOH in water is developed. The progress of the etching is monitored by the time dependance of the pH value. Quenching of the hydrolytic etching in ethanol is allowed to isolate mesoporous, monodisperse micrometer-sized silica particles with a pore volume of 160 μL g−1 and a pore-size range between 100 and 4 nm (>200% enhancement over the parent particle).","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 14","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202500536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681073","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}

Due to the manufacturing process, the material properties are heterogeneous, therefore requiring characterization methods to quantify local coating layer thicknesses for both research and process scale-up. Compared to microscopy, remanent magnetic scanning enables shorter turnaround times for the estimation of coating thickness. This study aims to improve quantitative characterization with magnetic scanning measurements by proposing an equivalent model for open-cell hybrid foams. This model helps to identify possible sources of deviations in the thickness-magnetic correlation that can occur in hybrid foams. Simulations reveal that several geometrical features contribute ambiguously to the magnetic field. The level of influence on the magnetic signal varies depending on the feature under investigation and its proximity to the surface. High influence is observed for displaced cells in the depth and vertical struts at varying depths compared to adjacent cells on the surface. This should be considered when using remanent magnetic scanning for the quantitative estimation of local coating thickness. In the future, more experimental data may help to use this approach for quantitative characterization of layer thicknesses and reduce ambiguity of the measured data.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 12","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309007","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}

After solution treatment, the alloys are subjected to room-temperature tensile testing. Characterization methods such as optical microscopy, scanning electron microscopy, electron backscattering diffraction, and transmission electron microscopy are used to analyze the microstructure of solution treatment. The results indicate that the microstructures of all four alloys are composed of grains with a single BCC structure. The room-temperature tensile test results indicate that as x increases, the yield strength of the alloy gradually decreases, while the plasticity gradually increases. On the basis of this experiment and to find an acceptable strengthening model, three solid solution strengthening models are introduced in this article, which are used to calculate the yield strength of solid solution alloys. The tensile yield strength of alloys is compared with the calculated values, and the differences between the three models and the error between the calculated results and experimental results are discussed. The results show that all three models can predict the yield strength of alloys well with an error of less than 8%; compared to other models, these models have smaller computational errors, among which the Varvenne model has a relatively small error.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 12","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308961","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}

The customized structure, supported with similar mechanical strength and interconnected porosity, would facilitate improved interfacial crosstalk. Herein, a fugitive templating technique is explored for fabricating tailorable open porous Ti6Al4V. Ti6Al4V powder-loaded slurry compositions are used to infiltrate fugitive templates with characteristics of 40, 30, and 20 pores per inch (PPI). The fabricated Ti6Al4V foam has open porosity ranging 73.8–91.7%, similar to trabecular bone. Further, the mechanical properties of foam are found to be in close proximity to trabecular bone. The sample of 40 PPI characteristics with different slurry combinations shows promising results compared to other fugitive templates. The Weibull modulus of all samples prepared using 40 PPI templates is evaluated to range between 3.14 and 11.31. Moreover, pore size distribution of the samples ranges from 422 ± 32.3 to 1148 ± 208 μm, with a porosity ranging from 73.8 ± 2.2 to 86.1 ± 0.8%. In vitro and in vivo studies confirm suitability of the samples for biological systems.

By systematically altering the Al2O3 content from 0 to 20 wt%, the research uncovers critical insights into the material's evolution. A striking increase in grain size, from 4.2 to 5.7 μm, occurs as Al2O3 content rises, despite maintaining uniformity across different regions of the composites. Mechanical testing reveals an intriguing trend: the ultimate tensile strength peaks at 640.8 MPa with just 6 wt% Al2O3, while higher Al2O3 content results in a reduction in strength, down to 566.4 MPa at 20 wt%. A notable finding is the significant variation in elongation, with the highest (13.4%) in the pure AA7075 matrix, contrasting sharply with the lowest (4.9%) in the 20 wt% Al2O3 composite. Most remarkably, the AA7075-6 wt% Al2O3 composite not only demonstrates the highest tensile strength but also exhibits the lowest wear rate (4.5 μg m−1), offering an exciting glimpse into the material's potential for advanced applications. This study reveals the delicate balance between microstructure and mechanical properties, unlocking the pathway to more durable and high-performance composites.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 12","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308838","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}

Increasing layer thickness is an effective strategy to enhance productivity. This study investigated the effect of layer thickness under comparable volumetric energy density in LPBF-processed AISI 420 stainless steels. The results show that relative densities exceeding 99.8% are achieved in all the samples. A duplex microstructure comprising a martensitic matrix and retained austenite is observed in the as-built specimens, with the retained austenite content increasing from 17.6 to 30.9% as the layer thickness increased from 40 to 80 μm. Subsequent austenitizing and tempering heat treatments result in the complete transformation of retained austenite into tempered martensite. The specimen manufactured from 80 μm layer thickness exhibits an excellent ultimate tensile strength of 1437 MPa along with an outstanding elongation of 12% after heat treatment. The enhanced mechanical performance is attributed to the decomposition of retained austenite and the formation of finely tempered martensite during heat treatment. This work demonstrates that by optimizing process and post-processing parameters, both productivity and mechanical properties can be simultaneously improved in LPBF-fabricated AISI 420 stainless steels, providing a promising pathway toward high-performance and high-efficiency additive manufacturing.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 12","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308950","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}

The evolution of long period stacking ordered (LPSO) phases and their effects on microstructure and dynamic recrystallization (DRX) mechanisms are systematically explored. The results show that the flow behavior is strain-rate-sensitive, transitioning from dynamic recovery (<0.1 s−1) to DRX (>0.1 s−1). The LPSO phases flatten and fragment during deformation, with fragmentation increasing at higher strain rates (0.01 → 10 s−1), causing volume fraction to first decrease (12.5% → 8.6%) then rise (17.2%). At 1 s−1, higher temperatures (400 → 500 °C) lead to LPSO aggregation, with volume fraction peaking at 14.1%. LPSO phases promote DRX via particle-stimulated nucleation and kink-induced continuous DRX. Optimal grain uniformity (2.21 μm) occurs at 400 °C/1 s−1 with 8.6% LPSO.

Three alloy variants with distinct Zr contents (0.02, 0.08, and 0.22 wt%) are comprehensively analyzed using transmission electron microscopy, electron probe microanalysis, and scanning electron microscopy equipped with energy dispersive X-ray spectroscopy. The results show that Zr addition significantly widens the solidification temperature range ΔT (23, 26, and 36 °C), which aggravates interdendritic segregation of Zr, Mo, and Mn. Zr-rich MC carbides (0.036, 0.131, and 0.249 wt%) that precipitate at grain boundaries undergo progressive dissolution during homogenization at 1200 °C and are accompanied by an increase in the diffusion coefficients of elements (Cr: 4.99, 5.78, and 6.63 × 10−15 m2 s−1; Mo: 3.85, 5.31, and 6.55 × 10−15 m2 s−1). Consequently, an appropriate amount of Zr microalloying can facilitate elemental diffusion throughout the homogenization process. However, an excessive Zr addition will trigger severe elemental segregation during solidification, which has a detrimental impact on the hot workability of subsequent alloys. Finally, the synergistic effect is thoroughly discussed, and the optimal Zr content is determined.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 12","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308948","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}
