However, the potential of additive manufacturing, specifically laser metal deposition (LMD), for producing complex components from titanium-microalloyed HSLA variants remains largely unexplored. This study addresses this research gap by investigating the manufacturing of Ti-doped FeC0.12Si0.25Mn1.3 via LMD for the first time. To comprehensively evaluate process-structure-property relationships under rapid solidification conditions, both elemental powder blends and gas-atomized prealloyed feedstocks were processed using varying shielding gas flow rates and thermal histories. Experimental results revealed that blended powders are highly susceptible to complex oxide formation, an issue significantly mitigated by increasing the shielding gas flow. Conversely, prealloyed powder demonstrated superior microstructural homogeneity in the as-built state. Subsequent postprocess annealing at 550°C successfully tempered local martensitic regions, effectively homogenizing the spatial hardness distribution across the build volume. With final hardness values reaching up to 284 HV1, the material exhibits mechanical performance competitive with conventional thermomechanically processed grades. While demonstrating the feasibility of this approach, the findings highlight the critical necessity of strict atmosphere control during LMD to minimize inclusions, suggesting future research on optimizing shielding strategies for large-scale deposition.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202502533","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696391","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 accumulation of these organisms, known as biofouling, on ship hulls can increase fuel consumption by up to 45%, causing higher emissions. Remedy is offered by nonbiocidal fouling-release (FR) coatings, which weaken the adhesion between organisms and surfaces, enabling removal by hydrodynamic forces or gravity. This study investigates the FR performance of biocide-free polyurethane, polyurea, and silicone-based systems in relation to their Young's modulus. The rationale is to better understand the influence of Young's modulus across different polymer classes. Within these classes, Young's modulus varies in a narrow range (0.2–2.2 MPa) to study its effect on FR behavior. In polyurethane and polyurea systems, modulus adjustments are made by altering resin-to-hardener ratios, affecting crosslink density. Coatings underwent static immersion in the North Sea, and FR performance is monitored monthly. After 15 weeks, samples are cleaned with a high-pressure water jet. Compared to a hard reference system, all soft coatings exhibit FR performance identical to Intersleek 1100 SR after full immersion period and cleaning, highlighting the importance of mechanical softness for effective fouling release.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202501661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696349","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}

Conventional SEM is a well-established and widely used technique to characterize material properties and surface structures in a variety of research fields. However, due to the high vacuum conditions used in conventional SEM, imaging delicate, nonconductive, and/or wet samples—which are particularly prevalent in life sciences—normally requires extensive sample preparation, such as critical point drying and sputter-coating, which can alter the sample properties. Here, ESEM offers a convenient solution, where nonconductive and wet biological samples can be imaged in their near-native state almost without sample preparation. The advantages of ESEM compared to conventional SEM for life sciences based on examples from literature and new application examples from biomaterials science and zoology are illustrated. Finally, recent advances in automated imaging and AI-based image processing are beginning to extend the current limits of resolution and sample stability in ESEM, potentially enabling more precise, real-time, and less damaging imaging of hydrated and beam-sensitive materials in future studies.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202502218","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686822","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}

For producing such MMC layers with high productivity, high-speed laser melt injection is developed. Since high laser intensities are required for reaching high process speeds, strong laser–powder interactions can occur resulting in undesired deformations and agglomerations of powder particles. Interactions can occur both during the particle transport from the nozzle to the melt pool and during the particle incorporation in the melt pool. This article focuses on the incorporation behavior of spherical fused tungsten carbide (SFTC) particles in the tool steel 1.2362. First, a simplified model is built in order to determine the factors affecting the incorporation. Second, the incorporation of SFTC particles is analyzed by high-speed imaging. It is found that the kinetic energy of the particles at the beginning of the incorporation has a decisive influence on the incorporation time. Whereas most particles are incorporated directly, 10% to 40% of the observed particles float on the melt pool surface before being incorporated.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696402","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}

Additive manufacturing enables creating customized orthopedic implants with complex geometries that combine mechanical stability with biological integration. The choice of biocompatible Ti-6Al-4V, together with the incorporation of lattice structures, offers improved mechanical performance, corrosion resistance, and bone ingrowth. A critical step toward the clinical adoption of such additively manufactured lattice structures is their thorough mechanical characterization, the central focus of this work. To this end, three test methods are employed to assess macroscopic mechanical response and damage tolerance: uniaxial compression, fourpoint bending and crack propagation tests. The results show that the mechanical properties depend on the lattice topology and surface finish. In particular, TPMS-based architectures (Triply Periodic Minimal Surfaces) exhibit superior fatigue crack propagation behavior, which is attributed to a more homogeneous stress distribution. In static testing, the SplitP TPMS (SPP) and Honeycomb (HCG) structures achieve the best balance of high stiffness (up to 27 GPa) and compressive strength (up to 249 MPa). These experimentally validated data form a crucial basis for subsequent artificial intelligence (AI)-based structural optimization to maximize the long-term mechanical reliability of implants under physiological loads.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202502233","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696325","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}

As aircraft maintenance plays a central role in the lifecycle of aviation components, optimizing these processes is essential for achieving long-term sustainability. Digitalization as a key enabler offers new ways to plan and execute repair processes more efficiently. A central element is the systematic collection and use of process data. In this research, detailed results from non-destructive testing such as visual inspections, and other diagnostic methods are captured in structured and standardized databases, organizations can create a digital memory of component conditions, defect histories, and repair outcomes. These databases allow for data-driven process planning, enabling maintenance teams to identify patterns, anticipate failure modes, and select repair strategies based on evidence rather than experience. Complementing this data-centric approach, simulation-based process planning is developed for virtual testing and optimization of repair procedures before carrying them out in practice. Through simulations, various repair scenarios can be evaluated in terms of time, cost, and environmental impact. This supports sustainable decision-making by minimizing waste, rework, and downtime. The effects of the proposed data-driven simulation models on sustainability are critically discussed.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202501718","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696318","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 work demonstrates the experimental realization of a serial snap-through system composed of monolithic, 3D-printed von Mises truss (VMT) units. The study examines how a small number of bistable elements, arranged in series, can function as a compact mechanical member with a controlled multistage response. Each unit is printed in a single operation with self-releasing hinges ensuring coaxial alignment, and incorporates a sliding support that may be locked or released to tune boundary stiffness and post-snap behavior. Chains of two to four VMTs display programmable responses with transitions and re-hardening stages governed by geometry, engagement gaps, and support constraints. A compact inverted-compliance model rationalizes these observations and extends them to cascades of arbitrary length. Expressing each unit through its nonlinear compliance δ(F) allows the model to recover measured behaviors and support analytical design of target sequences of elastic instabilities. The combination of an experimentally accessible serial architecture and a predictive model provides a practical route for achieving tailored responses in applications requiring staged energy absorption, force limitation, or controlled re-hardening.
