The alloys are processed using one-stage and two-stage homogenization followed by high-temperature solution treatment and T6 aging. Mechanical properties, including hardness, tensile strength, and ductility, are evaluated. Quench sensitivity is assessed by measuring the loss of hardness at varying distances from the water-quenched end. The results indicate that alloy B (5.4) exhibits the highest quench sensitivity due to higher precipitation kinetics. Additionally, the study reveals that the alloy with a higher Zn/Mg ratio (5.4) displays better precipitation strengthening but shows a more significant loss in hardness during quenching. SCC resistance is evaluated in both air and NaCl solution environments, showing that the alloy with a lower Zn/Mg ratio demonstrated better SCC resistance. These findings provide insights into optimizing the mechanical properties and resistance to SCC of AA7095 alloys through homogenization and Zn/Mg ratio control.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909130","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}

A voxel-based approach is employed as a numerical homogenization method to calculate the mechanical and thermal properties of the structures. LCD 3D printing is employed for experimental validation which demonstrates close agreement with finite element analysis with ≈5% deviation in predicted elastic modulus. The proposed IP and iBP architectures exhibit up to 15% higher thermal conductivity compared to their base TPMS structures, while maintaining almost similar elastic modulus, with only a 4% deviation. Also, the directional elastic properties of the modified TPMS architectures have been examined by the Zener anisotropy index. Compared to the base structures, both architectures exhibit high anisotropy at volume fraction of 40%, but the anisotropy decreases drastically as volume fraction increases to 60%. Additionally, detailed geometrical analysis of these architectures indicates that they exhibit three void phases at specific TPMS parameters. The results demonstrate that the developed architectures have high potential to be employed in heat and mass transfer systems, including multifluid heat exchangers.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909339","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}

Routinely used as fillers in composite materials, the prospect of using chemical surface modification to improve the performance of milled carbon fibers carries appeal. This work describes the adaptation of conventional electrochemical reduction of aryl diazonium salts to recycled milled carbon fibers and explores the improvements in mechanical performance achieved therein in a simple epoxy resin system. Increasing fiber mass loadings are examined using conventional unmodified milled carbon fiber, and two species of chemically modified fibers, one featuring benzyl alcohol and the other nitrophenyl groups. At low loadings, milled carbon fibers with a surface featuring aryl alcohol functionality significantly improve the mechanical properties of epoxy specimens, increasing flexural strength by an average of 35% and tensile strength by 31.5%. Significant improvements are also seen at low loadings (<1% w/w) using aryl nitro-modified fibers. It is proposed that fibers modified with these functionalities promote hydrogen-bonding at the fiber–polymer interface and result in greater mechanical performance, and that this improvement is pronounced at ≤1 wt%.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402306","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908900","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}

This study presents a novel monitoring approach using acoustic and optical emissions to diagnose and correct these fluctuations during DLIP structure fabrication. Experiments are conducted using a nanosecond-pulsed IR laser to create 6 μm periodic microstructures on stainless steel. Significant laser power fluctuations are observed over time, resulting in noticeable surface texture inhomogeneity across larger areas. Acoustic and optical emissions, recorded via microphone and photodiodes respectively, are found to correlate well with local structure depth, surface roughness, and macroscopic appearance of the textured surface. A strategy for in-process correction is demonstrated using a PI controller to adjust laser power based on acoustic emission feedback in the 18–22 kHz range during processing. Implementing this closed-loop control system achieves a homogeneous texture with a consistent 2 μm structure depth, compared to significant variations between 0.8 and 2.4 μm without the controller. This monitoring and control approach offers a simple, cost-effective solution for ensuring quality and consistency in large-area DLIP fabrication processes, potentially improving the reliability and efficiency of surface texturing applications.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402505","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908901","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}

In lead-cooled fast reactors (LFRs), lead-bismuth eutectic (LBE) serves as the coolant due to its superior thermal conductivity, low melting point, high boiling point, excellent fluidity, and radiation resistance. During the operation of LFRs, the core materials are in direct contact with LBE, making the compatibility between LBE and these materials a critical concern. It has been established that LBE is highly corrosive to metallic materials, posing significant challenges to the long-term safety and operational reliability of LFRs. Consequently, researchers have focused on developing a range of corrosion-resistant materials, among which high-entropy alloys (HEAs) have gained considerable attention in recent years due to their exceptional resistance to high-temperature corrosion and radiation damage. This review summarizes the recent advance research on HEAs and their coatings on corrosion resistance in LBE environments. The article examines the effects of alloy composition, microstructure, oxygen concentration, corrosion exposure time, and temperature on the corrosion resistance of HEAs. The findings offer valuable insights into material selection and surface protection strategies for critical reactor components in advanced nuclear reactors.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908903","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}
