High-entropy alloys (HEAs) have attracted growing interest for biomedical use because they can combine high strength, ductility, corrosion resistance and promising biocompatibility. Their multi-principal-element compositions and associated core effects enable microstructure and property combinations that differ from those of conventional alloys. This review systematically summarizes key design concepts and processing strategies for biomedical high-entropy alloys (bio-HEAs). Furthermore, we evaluate advanced fabrication routes, such as additive manufacturing, to achieve properties tailored to specific clinical requirements. By introducing machine learning-assisted alloy design, we finally discuss the potential of bio-HEAs to overcome the current limitations of conventional implant materials and also survey in detail their emerging applications in orthopedic implants, dental restorations, and cardiovascular stents. Overall, this review offers insights into the structure–function interplay of bio-HEAs and provides critical guidance for their future clinical translation.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 19","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100486","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}

Ultrafast laser pulses offer a promising alternative for localized amorphization, but achieving uniform transformations on large areas by consecutive pulses remains challenging, particularly at near-infrared wavelengths where the fluence window for amorphization before material damage is relatively narrow. In this work, we investigate the use of deep-ultraviolet (DUV, 258 nm) femtosecond pulses for producing continuous, uniform amorphous layers on Si(100) and Si(111). Single- and multi-pulse threshold analyses reveal that DUV provides a fluence window for amorphization up to six times larger than at 1030 nm, enabling over 30 successive shots per site without the occurrence of ablation by incubation effects. Using appropriate fluence and overlap conditions, we achieve uniform amorphous lines and areas with thickness of 20–45 nm. Electron microcopy analyses confirm high uniformity and sharp amorphous/crystalline interfaces (<1.5 nm). Time-resolved reflectivity measurements reveal melting and resolidification dynamics, with melt durations up to 2.5 ns without evidence of a counter-propagating solidification front. These results establish DUV femtosecond processing as a scalable route for direct writing of ultra-thin amorphous structures, advancing fabrication techniques for microelectronics and silicon photonics.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 19","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.71140","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100446","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 results reveal that temperature nonlinearly governs interfacial evolution through a competitive mechanism involving recrystallization, diffusion, and intermetallic compound (IMC) growth. Below 450 °C, the recrystallization fraction in the Cu layer increases substantially, whereas the high-stacking-fault-energy Al layer undergoes primarily dynamic recovery. At the optimal temperature of 450 °C, a continuous and stable IMC layer (∼8.2 μm) forms, achieving a synergistic balance between Cu recrystallization and interfacial bonding. Beyond 475 °C, however, accelerated interfacial reactions lead to IMC coarsening, Kirkendall voiding, and thermal stress cracking, resulting in brittle interfacial failure. Theoretical analysis indicates that the pulse current exerts a synergistic Joule-heating and electron-wind effect, which promotes preferential atomic migration along close-packed planes and releases residual stresses, thereby facilitating an optimized interface with low dislocation density and high orientation stability. This study provides a novel strategy for achieving reliable bonding of heterogeneous materials in aerospace lightweighting and electronic packaging applications.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 19","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100689","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}

Although ultrasonic vibration machining is feasible, the influence of ultrasonic process parameters on the machining effectiveness of CF/EP composite material remains poorly understood. This study employs ultrasonic vibration-assisted milling to compare conventional milling (CM), longitudinal ultrasonic vibration milling (LUVM), and longitudinal-torsional ultrasonic vibration milling (LTUVM). Variations in milling force, processing temperature, top and bottom surface edge damage, and surface morphology are analyzed. The damage suppression mechanisms under LTUVM are investigated, including fiber–resin interface stress, fiber fracture modes, and thermo-mechanical coupling with multidirectional vibration effects on edge damage. Results show all ultrasonic-assisted conditions outperform CM. LTUVM reduces milling force and temperature by up to 23% and 18% compared to LUVM, effectively minimizing warpage, burr, and tear. Surface defects are significantly suppressed, with much lower roughness than the other two conditions. This research explores the mechanisms of damage suppression under LTUVM, providing a basis for high-quality machining of carbon fiber-reinforced polymer composites.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 19","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100511","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}

This review examines HEA coatings fabricated by LC against the background of two decades of HEA development, focusing on preparation strategies, microstructure regulation, service performance, and unresolved mechanisms. The review traces the evolution from the discovery of HEAs by Cantor and Yeh in 2004 to contemporary advances in 2025. We analyze four preparation strategies: direct deposition, in situ ceramic phase synthesis through doping, multilayer gradient structures, and high-entropy amorphous coatings. The review evaluates how elemental additions (Cr, Mo, Al, Ti, Nb, Si) enhance performance through passivation film formation, solid solution strengthening, and precipitation hardening. Furthermore, we identify three fundamental challenges constraining industrial application: unclear three-dimensional structural features of short-range order, unpredictable “cocktail effects” in multicomponent systems, and poorly understood stress generation mechanisms during processing. Finally, we propose future research emphasizing in situ characterization, cross-scale modeling, and intelligent process optimization to bridge the gap between promising service performance and unresolved underlying mechanisms, ultimately enabling reliable design of next-generation protective coatings for extreme environments.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 19","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100485","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}
