The as-cast TNTZS alloy was solution-treated and aged at 450°C (HT450) and 550°C (HT550). Microstructural characterization revealed significant changes in the phase proportion (in vol%), which transformed from 64% β, 19% α, and 17% α″ in as-cast condition to 54% β, 13% α, and 33% α″ for HT450 and 55% β, 25% α, and 20% α″ for HT550, respectively. The tensile strength and yield strength increased from 608 and 424 MPa in as-cast condition to 1192 and 1180 MPa for HT450 and 921 and 819 MPa for HT550, respectively. The strengthening effect is mainly attributed to the increase in martensite α″ phase after aging treatment. HT550 exhibited excellent corrosion resistance, with a reduced corrosion current density and increased passive film resistance. The improved corrosion resistance is owing to the denser lattice structure of β and the formation of a thicker and denser passivation film with smaller interatomic spacing.

By coupling geometrical topology with intrinsic material behavior, we demonstrate how anisotropic microstructural response can inform the design of optimized lattice structures.

These alloys exhibit markedly different mechanical responses under multiaxial loading in “fully dense” solid form. The strut-level stress analysis of these alloys reveals how specific microstructural characteristics can guide the selection of appropriate lattice topologies. Two representative lattice configurations, one stretching-dominated and one bending-dominated, are evaluated under identical loading conditions to explore how microstructure-driven design can lead to topology choices that are better suited to accommodate shear or other critical local stress states, thereby enhancing mechanical performance. A strut-level mechanics-based analysis is performed to evaluate shear stress distribution and highlight the role of topology-microstructure synergy and compatibility in determining overall lattice behavior. The findings emphasize the importance of designing structures that are both load-aware and microstructure-responsive, enabling more effective material utilization in advanced engineering applications.</p>","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 13","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534211","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}

How the cooling rate specifically controls PDC microstructural evolution to enhance performance remains unclear. his study systematically investigates the effect of cooling rate after high-temperature treatment on PDC microstructure and performance. The slower cooling rate preserves diamond–diamond bonding, inhibits graphitization, and promotes a more uniform cobalt distribution along diamond grain boundaries. Nanohardness increases from 76 to 85 GPa; interfacial shear strength increases from 985 to 1009 MPa; wear resistance improves by approximately 33%; and impact resistance also increases.

This makes them a critical material choice for applications in aerospace, automotive, and transport sectors where reducing the mass without compromising mechanical integrity is essential. Recently, additive manufacturing has been adopted as an advanced manufacturing technique to precisely place continuous fibre reinforcements within polymeric matrices. These additive manufacturing techniques increased freedom in the design and fabrication of polymeric composites by allowing control of fibre density and orientation and as a result tailoring material behaviour at the local material points. This capability also allows engineers to design and manufacture complex geometries with CFRP composites that were not achievable through traditional composite fabrication methods. This review first highlights the state-of-the-art in additive manufacturing of continuous fibre-reinforced polymer composites and then focusses on different aspects of the domain, including discussions on conventional and novel additive manufacturing techniques, mechanical characterisation and testing methods, numerical and computational modelling approaches, various functional applications, and sustainability of additive manufacturing polymeric composites. This review also aims to provide insight into the current body of work, existing limitations, and emerging research frontiers related to the advantages of reinforcing composites with fibres through the additive manufacturing process.

However, its susceptibility to biofouling and corrosion significantly limits its application, leading to substantial economic losses. Although laser texturing, fluorinated modification, and electrochemical evaluation of copper have been studied separately, the combined application of picosecond laser treatment and fluoroalkylsilane (FAS) modification, together with biologically conditioned electrochemical evaluation, remains insufficiently explored. This study develops a superhydrophobic protective layer on copper surfaces using a composite modification technique that integrates picosecond laser treatment with FAS. The wetting behavior, adhesion characteristics, and corrosion resistance of the modified surfaces under biofouling conditions were systematically evaluated. The resulting surface exhibited a static contact angle (CA) of 156° ± 0.47° and a low rolling angle of 6° ± 0.5°. Corrosion resistance was evaluated through potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). Electrochemical tests confirmed the modified layer effectively mitigated electrochemical corrosion of copper in bacterial suspensions, as evidenced by a reduced corrosion current, a positive shift in corrosion potential, and an increased polarization resistance. The results indicate that the picosecond laser–FAS composite treatment significantly enhances the antimicrobial adhesion resistance and corrosion resistance of copper surfaces, supporting potential applications in infrastructure, marine engineering, and healthcare.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394464","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}

The setup enables experiments under air, argon, and argon–silane atmospheres, allowing targeted investigation of oxygen-related effects on material removal. High-speed imaging captures chip formation and chip-grain interactions during the process, while scanning electron microscopy and metallographic analysis provide complementary information on grain condition and material adhesion. Validation experiments demonstrate reliable and repeatable scratching under oxygen-reduced and oxygen-free conditions. Within the investigated parameter range, the measured normal and tangential forces show no clearly distinguishable systematic dependence on atmosphere, although potential effects may be masked by variations in grain geometry and effective depth of cut. In contrast, pronounced differences in chip adhesion behavior are observed. In ambient air, rapid chip detachment is promoted, associated with formation of a thin passivating titanium oxide layer. Under oxygen-reduced conditions, suppressed oxidation leads to increased adhesion and local material accumulation on the grain.

In this article, the surface tension of Ti-6Al-4V is derived from the oscillation of falling droplets using Rayleigh's formula. Conventional levitating droplet techniques for reactive materials require complex evaluation algorithms and specialized hardware to maintain microgravity conditions. In contrast, the presented approach employs only a single high-speed camera for simultaneous temperature and droplet oscillation measurements, enabling flexible and cost-effective integration into various technical systems.
