Al-Si alloys are commonly used in the automotive and aircraft industry because of their excellent strength-to-weight ratio. Due to the laser powder bed fusion manufacturing process, inhomogeneous cooling affects the microstructure as well as defect distributions. Within this paper, the uniform fatigue damage tolerance assessment was further qualified for (miniature) bending specimens with different loaded volumes based on the concepts according to Murakami (√area) and Shiozawa for an initial defect-based model. These approaches were used to calculate defect-related fatigue life curves, in which the cyclic stress intensity factor (ΔK) at the initiating defect (√area) was used to represent local stress concentration at the crack tip instead of nominal stress-based S-N curves. Results of S-N curves did not allow a precise lifetime prediction due to increasing effect of manufacturing-related defect distributions, while fracture mechanical approaches enable a uniform fatigue lifetime description of different testing volumes. The calculated fatigue limit and short crack threshold value suggested by Noguchi based on the extended approach of Murakami need to be compared and validated experimentally. Furthermore, the effects of miniaturization and crack propagation have been identified and considered. Uniform fatigue life predictions and efficient materials testing have been combined and show potential for future research.

由于铝硅合金具有出色的强度重量比，因此常用于汽车和飞机工业。由于采用激光粉末熔床制造工艺，不均匀冷却会影响微观结构和缺陷分布。本文根据 Murakami (√area) 和 Shiozawa 对基于缺陷的初始模型的概念，对具有不同加载体积的（微型）弯曲试样的均匀疲劳损伤容限评估进行了进一步鉴定。这些方法被用于计算与缺陷相关的疲劳寿命曲线，其中起始缺陷 (√area) 处的循环应力强度因子 (ΔK) 被用来表示裂纹尖端的局部应力集中，而不是基于名义应力的 S-N 曲线。由于与制造有关的缺陷分布的影响越来越大，S-N 曲线的结果无法精确预测寿命，而断裂力学方法可以对不同的测试体积进行统一的疲劳寿命描述。Noguchi 根据 Murakami 的扩展方法计算出的疲劳极限和短裂纹阈值需要进行比较和实验验证。此外，还确定并考虑了微型化和裂纹扩展的影响。统一的疲劳寿命预测与高效的材料测试相结合，显示了未来研究的潜力。

With the rapid growth of information flux, integrating more channels in limited spaces has been a critical requirement for highly-integrated long-range parallel transmissions. Although meta-waveguides, such as spoof surface plasmon polariton (SSPP) waveguides, can suppress crosstalk between adjacent channels, it is still urgent to seek new methods to further increase the number of channels without occupying additional space. Here, we propose a reconfigurable dual-mode meta-waveguide (RDMMW) by integrating diodes into meta-units, which supports two independent channels using two orthogonal modes. The RDMMW can be switched among dual-mode, even-mode, odd-mode and cutoff states by controlling the diodes, which provides more freedom to manipulate the channel features. The RDMMW possess two outstanding merits in highly-integrated long-range parallel transmissions, including lower coupling between two channels than conventional single-mode waveguides and constant mode coupling in longer waveguides. Thus the proposed RDMMW has advantages of multi-mode, reconfiguration, low coupling and high integration density, providing a new avenue to realize highly-integrated multi-functional systems.

随着信息流量的快速增长，在有限空间内集成更多信道已成为高度集成远距离并行传输的关键要求。尽管元波导（如欺骗性表面等离子体极化子（SSPP）波导）可以抑制相邻信道之间的串扰，但在不占用额外空间的情况下进一步增加信道数量仍然迫切需要寻求新的方法。在此，我们提出了一种可重新配置的双模元波导（RDMMW），它将二极管集成到元单元中，利用两种正交模式支持两个独立的信道。通过控制二极管，RDMMW 可以在双模、偶模、奇模和截止状态之间切换，从而为操纵信道特性提供了更大的自由度。与传统单模波导相比，RDMMW 在高度集成的长距离并行传输中具有两个突出优点，包括双通道之间的耦合更低，以及在较长的波导中具有恒定的模式耦合。因此，所提出的 RDMMW 具有多模、可重构、低耦合和高集成度等优点，为实现高度集成的多功能系统提供了一条新途径。

A design strategy for 3D layer-to-layer angle interlock woven composites has been established by employing a set of three key properties of the weave (KPoWs): the global fibre volume fraction, the interlocking angle and the ratio of the weft tow volume to the warp tow volume. Using analytically derived expressions of the KPoWs, their variation trends relative to the manufacturing parameters have been revealed. At the same time, via a range of systematic computational material characterisation exercises, the KPoWs were shown to be sufficient for representing the woven reinforcement as far as the elastic behaviour predictions are concerned, because the effective elastic properties were found to follow consistent variation trends with the KPoWs. As a result, through use of KPoWs, manufacturing parameters have been associated with the effective elastic properties in a systematic manner. This offer means for obtaining a desirable elastic behaviour of 3D woven composites via variation of their internal architecture. The design method developed is the alternative to trial-and-error-based selection method conventionally adopted for this type of materials. As an example of application of the proposed method, a woven composite with balanced weft and warp properties has been designed.

通过使用编织物的三个关键属性（KPoWs）：全纤维体积分数、互锁角度和纬纱束体积与经纱束体积之比，建立了三维层对层角度互锁编织复合材料的设计策略。通过分析得出的 KPoWs 表达式，揭示了它们相对于制造参数的变化趋势。同时，通过一系列系统计算材料特性的练习，KPoWs 被证明足以代表编织加固材料的弹性行为预测，因为有效弹性特性与 KPoWs 的变化趋势一致。因此，通过使用 KPoWs，可以系统地将制造参数与有效弹性特性联系起来。这为通过改变三维编织复合材料的内部结构获得理想的弹性性能提供了方法。所开发的设计方法可替代此类材料通常采用的基于试错的选择方法。作为应用所提方法的一个实例，我们设计了一种经纬性能平衡的编织复合材料。

Owing to their disadvantages of broadband discontinuity, infinite value, or incapability of distinguishing cross-polarization conversions from co-polarization conversions, the traditional linear polarization discrimination methods relating to the phase difference Δφ, the ellipticity angle β, or the axial ratio are inapplicable to the software-based optimal design of broadband cross-polarization conversion metasurfaces (CPMs) consisting of subblocks. Therefore, we introduce the pseudo ellipticity angle β' to characterize the cross-polarization conversion. And based upon the coding metasurfaces and β', this work first employs the Python-programmed binary particle swarm optimization algorithm to accomplish the optimal design of reflective broadband CPMs. Then, the obtained CPM is further simplified by reprocessing the relatively isolated subblocks, which results in the final CPM. The simulated results show that the final CPM realizes the broadband cross-polarization conversion with β' ≥ 0.4π and a relative bandwidth of 36.1 % from 11.66 GHz to 16.79 GHz. Moreover, the measured results are in excellent agreements with the simulated ones, which validates the proposed design method. It advances the broadband CPMs design from manual to automated method.

传统的线性极化鉴别方法包括相位差Δφ、椭圆度角β或轴向比，由于这些方法存在宽带不连续性、数值无穷大或无法区分交叉极化转换和共极化转换等缺点，因此不适用于由子块组成的宽带交叉极化转换元表面（CPM）的软件优化设计。因此，我们引入了伪椭圆度角 β' 来表征跨极化转换。基于编码元曲面和 β'，本研究首先采用 Python 编程的二元粒子群优化算法来完成反射式宽带 CPM 的优化设计。然后，通过对相对孤立的子块进行再处理，进一步简化得到的 CPM，从而得到最终的 CPM。仿真结果表明，最终的 CPM 实现了宽带跨极化转换，β'≥ 0.4π，相对带宽从 11.66 GHz 到 16.79 GHz 为 36.1%。此外，测量结果与模拟结果非常吻合，验证了所提出的设计方法。它将宽带 CPM 设计从手工方法推进到了自动化方法。

Crystal plasticity models are powerful tools for predicting the deformation behaviour of polycrystalline materials accounting for underlying grain morphology and texture. These models typically have a large number of parameters, an understanding of which is required to effectively calibrate and apply the model. This study presents a structured framework for the global sensitivity analysis of the effect of crystal plasticity parameters on model outputs. Due to the computational cost of evaluating crystal plasticity models multiple times within a finite element framework, a Gaussian process regression surrogate was constructed and used to conduct the sensitivity analysis. Influential parameters from the sensitivity analysis were carried forward for calibration using both a local Nelder-Mead and global differential evolution optimisation algorithm. The results show that the surrogate based global sensitivity analysis is able to efficiently identify influential crystal plasticity parameters and parameter combinations. Comparison of the Nelder-Mead and differential evolution algorithms demonstrated that only the differential evolution algorithm was able to reliably find the global optimum due to the presence of local minima in the calibration objective function. However, the performance of the differential evolution algorithm was dependent on the optimisation hyperparameters selected.

晶体塑性模型是预测多晶材料变形行为的强大工具，它考虑了潜在的晶粒形态和纹理。这些模型通常有大量参数，需要了解这些参数才能有效地校准和应用模型。本研究为晶体塑性参数对模型输出影响的全局敏感性分析提供了一个结构化框架。由于在有限元框架内对晶体塑性模型进行多次评估的计算成本较高，因此构建了一个高斯过程回归替代模型，并用于进行敏感性分析。使用局部 Nelder-Mead 和全局微分进化优化算法对敏感性分析中的影响参数进行校准。结果表明，基于代理的全局灵敏度分析能够有效地确定有影响的晶体塑性参数和参数组合。对 Nelder-Mead 算法和微分进化算法的比较表明，由于校准目标函数中存在局部最小值，只有微分进化算法能够可靠地找到全局最优值。不过，微分进化算法的性能取决于所选的优化超参数。

This research aimed to enhance the strength and ductility of spray formed (SFed) 7050 aluminum (Al) alloy through hot extrusion and subsequent heat treatment. Microstructure and mechanical properties evolution during these processes were investigated. It was found that the low densification of the SFed 7050 Al alloy due to various defects such as pores, with an average size of 7.6 μm and an area fraction of 3.7 % could be notably enhanced by hot extrusion, even achieving a level close to theoretical density. This process led to a transformation of grains from equiaxed to elongated shapes along extrusion direction and significant grain refinement, exhibiting a strong fiber texture. While the employed extrusion ratio exceeds 16 with proper heat treatment, the SFed 7050 Al alloys achieves superior strength-ductility combination compared with reported Al alloys. The achieved high performance should be attributed to the grain refinement, strong texture and high densification that suppress defect-induced plastic instability. Furthermore, the combination of hot extrusion and heat treatment, provides an effective way to enhance strength and ductility for SFed 7050 Al alloy.

本研究旨在通过热挤压和后续热处理提高喷射成形（SFed）7050 铝合金的强度和延展性。研究了这些过程中的微观结构和机械性能演变。研究发现，SFed 7050 铝合金因各种缺陷（如平均尺寸为 7.6 μm、面积分数为 3.7 % 的气孔）而导致的低致密性可以通过热挤压得到显著提高，甚至达到接近理论密度的水平。在这一过程中，晶粒沿挤压方向由等轴形转变为细长形，晶粒明显细化，呈现出强烈的纤维纹理。与已报道的铝合金相比，SFed 7050 铝合金在适当热处理后的挤压比超过了 16，实现了更优越的强度-电导率组合。所取得的高性能应归功于晶粒细化、质地坚固和高致密性，它们抑制了缺陷引起的塑性不稳定性。此外，热挤压和热处理的结合为提高 SFed 7050 Al 合金的强度和延展性提供了有效途径。

Precision machining operations often lead to the failure of protective coatings on cutting tools due to common issues such as cracking, delamination, and peeling from cyclic impacts. While material selection and structural design are crucial for enhancing impact resistance, they primarily focus on static performance with limited consideration from the dynamic sights. This paper presents a novel dynamic design method for coatings, viewed through the lens of stress waves. We investigate the propagation behavior of stress waves in TaN/TiN and CrN/TiN coatings with layered structures. Our findings indicate that the attenuation of stress waves is dominated by the physical properties on both sides of the interface and the stride length. For interfaces with similar physical properties, the attenuation of stress waves is insensitive to the stride length, while for interfaces with different physical properties, the attenuation is regulated by the ratio of single-layer thickness to the full width at half maximum of the stress wave. These insights offer a strategy for extending the life of coatings and improving process safety under dynamic shocks.

精密加工操作通常会导致切削工具上的保护涂层失效，常见的问题包括循环冲击造成的开裂、分层和剥落。虽然材料选择和结构设计对提高抗冲击性至关重要，但它们主要关注静态性能，对动态视角的考虑有限。本文从应力波的角度出发，介绍了一种新颖的涂层动态设计方法。我们研究了应力波在具有层状结构的 TaN/TiN 和 CrN/TiN 涂层中的传播行为。我们的研究结果表明，应力波的衰减受界面两侧的物理性质和跨距长度的影响。对于具有相似物理特性的界面，应力波的衰减对跨距长度不敏感，而对于具有不同物理特性的界面，应力波的衰减受单层厚度与应力波半最大全宽之比的调节。这些见解为延长涂层寿命和提高动态冲击下的工艺安全性提供了策略。

These insights offer a strategy for extending the life of coatings and improving process safety under dynamic shocks.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"247 ","pages":"Article 113441"},"PeriodicalIF":7.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cesium lead bromide (CsPbBr₃) perovskite nanoparticles (NPs) are widely recognized for their high potential for next-generation optoelectronic devices. However, these NPs’ conventional surface-capped organic ligands with high fluidity are frequently shed from particles during separation and purification steps, significantly reducing their stability. Therefore, a simple method to improve the strength of perovskite NPs is essential. Here, we utilized salicylic acid (SA), which acts as a ligand and protective coating of luminescent NPs, to create CsPbBr₃@SA crystals using a straightforward standing technique. The CsPbBr₃ NPs were perfectly encapsulated and size-limited in the SA hollow space needle-shaped crystals that retain their significant optical intensity. The fluorescence emission intensity of CsPbBr₃@SA crystals without additional treatment can be maintained for six weeks under normal ambient conditions, demonstrating the SA ligand’s ability to protect CsPbBr₃ NPs better. Furthermore, the green emission CsPbBr₃@SA crystals are combined with K₂SiF₆ red phosphor and packed with a commercially available blue light emitting diode (LED) chip to fabricate a high gamut area white LED device. The highly straightforward standing method successfully enables the high-potential preparation of perovskite nanoparticles for future practical applications.

溴化铯铅（CsPbBr3）包晶纳米粒子（NPs）因其在下一代光电设备中的巨大潜力而得到广泛认可。然而，这些 NPs 具有高流动性的传统表面封端有机配体在分离和纯化步骤中经常从颗粒中脱落，大大降低了其稳定性。因此，必须采用一种简单的方法来提高过氧化物氮氧化物的强度。在这里，我们利用水杨酸（SA）作为配体和发光 NPs 的保护层，通过直接的静置技术制造出 CsPbBr3@SA 晶体。CsPbBr3 NPs 被完美地封装在 SA 中空针状晶体中，且尺寸受限，保持了显著的光学强度。在正常环境条件下，CsPbBr3@SA 晶体无需额外处理，其荧光发射强度可维持六周，这表明 SA 配体能更好地保护 CsPbBr3 NPs。此外，绿色发射的 CsPbBr3@SA 晶体与 K2SiF6 红色荧光粉相结合，并与市售的蓝色发光二极管（LED）芯片封装在一起，制成了高色域面积的白色 LED 器件。这种非常简单的制备方法成功地制备出了极具潜力的包光体纳米粒子，可用于未来的实际应用。

The solute diffusion zone plays a critical role in determining nucleation efficiency during heterogeneous nucleation. In this study, in-situ synchrotron X-radiography and numerical modeling were employed to investigate the Solute Suppressed Nucleation Zone (SSNZ) surrounding growing equiaxed grains in Al-13Cu alloys. Quantitative analysis of SSNZ and constitutional undercooling was conducted using image processing techniques. Solute concentration and SSNZ length in the <110> direction exceed those in the <100> direction, suggesting higher solute enrichment in dendrite centers. This causes greater undercooling in the dendrite growth direction (<100>) with faster dendrite growth rates. As equiaxed dendrites grow, SSNZ length in the <100> direction decreases while increasing significantly in the <110> direction. Utilizing data obtained from numerical simulations, we refined the analytical equation governing solute distribution preceding the solid–liquid interface under three-dimensional conditions, and the computational equation determining the SSNZ length. The SSNZ lengths derived from the optimized equation along the <100> and <110> directions demonstrate more agreement with both experimental observations and numerical simulation outcomes. Higher growth rates rapidly increase undercooling, limiting the development of nucleation-free zone. Additionally, SSNZ area growth slows at higher cooling rate, correlating with increased solute concentration and reduced area in SSNZ.

在异质成核过程中，溶质扩散区对成核效率起着至关重要的作用。本研究采用原位同步辐射 X 射线成像和数值建模方法，研究了 Al-13Cu 合金中生长的等轴晶粒周围的溶质抑制成核区（SSNZ）。利用图像处理技术对 SSNZ 和组织过冷进行了定量分析。在<110>方向上的溶质浓度和 SSNZ 长度超过了<100>方向上的溶质浓度和 SSNZ 长度，这表明树枝状晶中心的溶质富集程度较高。这导致树枝状突起生长方向（<100>）的过冷度更高，树枝状突起生长速度更快。随着等轴枝晶的生长，<100>方向上的 SSNZ 长度会减少，而<110>方向上的 SSNZ 长度则会显著增加。利用数值模拟获得的数据，我们完善了三维条件下固液界面前溶质分布的解析方程，以及确定 SSNZ 长度的计算方程。根据优化方程得出的 SSNZ 长度沿 <100> 和 <110>方向与实验观察和数值模拟结果更加吻合。较高的生长率会迅速增加过冷度，从而限制无核区的发展。此外，冷却速率越高，无核区面积增长越慢，这与溶质浓度增加和无核区面积减少有关。

Nowadays, packaging technologies have been extensively developed, including active and intelligent packages able to promote quality, safety, and the product shelf life. At this purpose, the aim of the study was focused on the design and development of polyvinyl alcohol-based nanofibers doped with two natural clays, montmorillonite or clinoptilolite, and loaded with chlorogenic acid, as nanofibrous membranes to control microbial contamination and oxidative state upon direct contact. The results showed that the 1 % w/w clay doping was the optimal concentration to obtain continuous and uniform nanofibers. In addition, chlorogenic acid loading (5 % w/w) into the nanofibers did not change the systems morphology, resulting in a chlorogenic acid sustained release, achieving 100 % within 24 h for all the systems with enhanced antioxidant and antimicrobial activities. Depending on their structure, the presence of the clays mineral was able to affect the aqueous vapor permeability. These results suggested the promising applications of the clay doped polyvinyl alcohol-based nanofibrous membranes as smart advanced material able to control microbial contamination and oxidative degradation to be used in biomedical field or as active packaging.

如今，包装技术得到了广泛的发展，其中包括能够提高质量、安全性和产品保质期的活性智能包装。为此，本研究旨在设计和开发掺杂了蒙脱石或绿原酸两种天然粘土的聚乙烯醇基纳米纤维，作为纳米纤维膜来控制微生物污染和直接接触时的氧化状态。结果表明，1% w/w 粘土掺杂是获得连续均匀纳米纤维的最佳浓度。此外，在纳米纤维中添加绿原酸（5% w/w）不会改变系统的形态，从而实现了绿原酸的持续释放，在所有系统中，绿原酸在 24 小时内的释放量都达到了 100%，并增强了抗氧化和抗菌活性。根据其结构的不同，粘土矿物的存在会影响水蒸气的渗透性。这些结果表明，掺杂粘土的聚乙烯醇基纳米纤维膜作为智能先进材料具有广阔的应用前景，能够控制微生物污染和氧化降解，可用于生物医学领域或活性包装。
