After heat treatment at 750 °C, TiNi and Ti2AlN MAX phase crystal structures are obtained in these films. The effects of different layer numbers on the structural, mechanical, tribological, adhesion, and fatigue properties of TiNi/Ti2AlN multilayer films are investigated. All films’ thickness is measured to be ≈2 μm. The 20 layers film deposited on Inconel 718 exhibited the best mechanical properties, with a hardness of 30.6 GPa and an elastic modulus of 407 GPa. A significant improvement in the tribological performance of the films is observed with an increasing number of layers. The lowest wear rate, calculated as 1.96 × 10−5 (mm3 (N·m)−1), is observed for the 20 layers film deposited on Inconel 718 at room temperature. At high temperatures, the friction coefficients of the 16 and 20 layers films deposited on Inconel 718 decreased to 0.25. In terms of adhesion properties, the 10 layers films deposited on AISI M2 steel demonstrated the best performance with a critical load value of 45 N. The results of the multipass scratch test clearly showed that the 20 layers film deposited on Inconel 718 exhibited the best fatigue behavior among all films.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801759","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 the production of a large number of such recycled magnets, these are installed in the demonstrators. Measurements on various test benches show that the demonstrators with recycled or reused magnets exhibit across the entire rotation speed range a similar or higher electromotive force or induced voltage as compared to their counterparts with primary magnets. While the e-Scooter motor achieves almost the same induced voltage (–0.7%) by using recycled magnets, the Hoverboard motor shows even an increased voltage of 6.7%. In the case of the Pedelec motor, the reuse of EoL-magnets leads to a voltage increase of 0.9% compared to the use of primary magnets.

This study investigates the effects of varying anodization parameters on TiO2 nanotubes, nanograss, and nanolace formation. Field-emission scanning electron microscopy is employed to analyze these nanostructures’ morphology and growth rates. The structural characteristics of the resulting nanostructures are precisely controlled by adjusting temperature, water content, duration, and applied potential during the anodization process. Nanotube length and diameter are influenced by ethylene glycol (EG) concentration, applied voltage, and temperature. The quantity of nanograss is determined by the anodization temperature. Nanolace formation is affected by hydrofluoric acid (HF) pretreatment of titanium foil. The results demonstrate that higher EG concentrations and applied potentials produce longer nanotubes, whereas lower EG concentrations with higher potentials result in larger nanotube diameters. Temperature variations control the amount of nanograss. HF pretreatment facilitates the formation of a hexagonal nanolace network on the surface. By tailoring synthesis conditions, this study provides a method for controlling the morphology of TiO2 nanostructures. These findings have implications for optimizing TiO2 nanostructures in sensors, photocatalysis, and other areas of nanotechnology, where specific structural properties are crucial for enhanced performance.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402227","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801502","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}

Despite efforts made to recycle the waste materials by secondary synthesis, the synthesized materials are limited by downgrade use due to the lower properties compared to that of the primary ones. Herein, a sustainable strategy for developing strong and multifunctional green multicomponent alloys (MCAs) using cheap scrap materials without the targeted functions is introduced. Assisted by thermodynamic calculations, the green MCAs with thermally stable ordered multicomponent B2 nanoparticles embedded in disordered multicomponent body-centered cubic matrix with high interfacial coherency have been designed and synthesized using scrapped aluminum alloys and stainless steels as the feedstocks. The multicomponent disordered–ordered structures enable a joint regulation of dislocation behavior, scattering of conduction electrons, and motion of magnetic domain walls, leading to high strength and deformability, high and stable resistivity below 923 K, low coercivities, and moderate saturation induction. These properties render the low-cost and green MCAs to be promising candidate materials in future sustainable high-precision electronic instruments and high-frequency magnetic components, even under harsh mechanical loads.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402307","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801508","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 straight, curved zigzag and their symmetrical counterparts serve as inspiration for the design of a novel biomimetic tube. To enhance the mechanical performance of these tubes, circumferential stiffeners are incorporated, varying in both quantity and arrangement. Various samples are fabricated using additive manufacturing, and experimental testing combined with finite-element analysis is employed to assess deformation behavior, energy absorption (EA), specific EA (SEA), and effective Young's modulus (Eeff). Results demonstrate that the addition of stiffeners significantly enhances the EA capacity and deformation behavior by varying the overall Poisson's ratio and enhancing stiffness. Straight zigzag tubes exhibit the highest stiffness, while symmetric curved zigzag tubes show up to a 33% improvement in effective modulus with stiffener integration. Nonsymmetric configurations enhanced by stiffener integration demonstrate superior EA up to 52%. Stiffeners enhance SEA by up to 42% in curved zigzag tubes. The parametric study further emphasizes the critical role of geometric parameters in optimizing mechanical performance.

Conductive polymer composites have gained increasing attention as strain sensors owing to their potential advantages. In this study, the effect of different polymer matrices and varying carbon nanotube (CNT) loadings by fabricating sandwich-structured polydimethylsiloxane (PDMS)/CNT and thermoplastic polyurethane (TPU)/CNT strain sensors is investigated using a solution mixing process. The uniform dispersion of CNTs in both PDMS/CNT and TPU/CNT nanocomposites facilitates proper electrical conductivity. PDMS/CNT6% and TPU/CNT6% strain sensors demonstrate higher linear performance under monotonic strains up to 20% compared to other samples. In cyclic stress–strain tests, PDMS/CNT strain sensors perform more efficiently and have an immediate response compared to TPU/CNT strain sensors, which exhibit the shoulder peak phenomenon. This phenomenon occurs due to the mechanical properties and hysteresis of TPU matrices. In these findings, it is revealed that the relative standard deviation % (RSD%) values of PDMS/CNT strain sensors are smaller than TPU/CNT, which confirms the considerable repeatability of PDMS/CNT strain sensors. Furthermore, PDMS/CNT6% offers effective detection of human body motion, such as finger joint movements with different bending angles and wrist joint bending at various bending rates. In the present study, a guideline is provided for material selection for fabricating flexible strain sensors.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801509","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}
