Herein, we delicately constructed a coaxial nanocable-like structure containing Cu foam-supported CuO NWs as core and Ni(OH)₂@FeOOH heterogeneous nanosheets as a porous sheath (<em>i.e.</em>, CuO@Ni(OH)₂@FeOOH NWs/CF). The particular architecture with 1D nanoarray frameworks <em>in-situ</em> grown on 3D conductive substrate and hierarchical microstructure ensures the adequate exposure of the active sites, facilitative electron/mass transfer, and high structural stability. Combined experimentation and DFT calculation demonstrate that Ni(OH)₂ and CuO in the hybrid served as active metal ions and scaffold for providing a fast electron conducting path, respectively. Meanwhile, FeOOH acted as an inductive agent to attract charge reorganization of adjacent Ni sites, thus modulating the electron structure and optimizing the <em>d</em>-band centers. Strengthened by the above desirable characteristics, CuO@Ni(OH)₂@FeOOH NWs/CF exhibited superior electrocatalytic activities towards both OER and UOR with a small overpotential of 310 mV and low potential of 1.37 V at 100 mA cm⁻², respectively, as well as the expected electrocatalytic stability. This work affords a way to design highly active catalysts <em>via</em> constructing heterojunctions for various applications.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"20 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The microstructure evolution along the depth direction varies in a nanocrystalline, equiaxial dendrites, columnar dendrites gradient, respectively. Noticeably, amorphous grain boundaries and carbide nanoprecipitates could be identified within the topmost surface nanocrystalline layer owing to the extremely high cooling rate during remelting, which exhibits the highest hardness and wear resistance (microhardness of ∼1136 HV, and wear rate of 4.36 × 10⁻⁶ mm³/(m N)). The superior wear resistance is mainly attributed to the synergistic nanocrystalline–amorphous deformation and gradient refinement effects. Meanwhile, multi-scale carbides effectively impede dislocation motion and further improve strength and wear resistance at different depths. This gradient structure provides promising insights into the design of high-performance wear-resistant alloys.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"119 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, traditional regeneration techniques are usually too complicated and difficult to industrialize, especially no longer applicable to severely degraded LFP cathodes. Herein, we report a novel physically confined-domain pressure sintering method for large-scale direct regeneration of severely degraded spent LFP cathodes (less than 20% residual capacity). By constructing physically confined domains, the interface interaction between lithium ions (Li⁺) and the cathode is enhanced and the potential barrier during relithiation is thus decreased, facilitating the insertion of Li⁺ into vacancies. The internal residual conductive carbon builds a reduced circumstance to promote the conversion of the Fe (III) to Fe (II) phase and reduce the Li-Fe anti-site (Fe_Li) defects. The broken small particles (heterogeneous phase) are in-situ re-synthesized into complete olivine structures driven by external pressures. The capacity retention of the regenerated LFP cathodes was 88.8% after 1500 cycles at 5 C. This work provides one-step, highly efficient, and scalable technology for direct regeneration of severely degraded LFP into high-performance cathode materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"23 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Process parameter optimization resulted in near-fully dense samples (&lt; 0.1% porosity) under optimal conditions. The microstructure and mechanical properties of TNZF alloy were then tailored using two chessboard scanning strategies and a simple scanning strategy. Samples fabricated using the chessboard scanning strategy (CS-TNZF) benefited from a lower thermal gradient, the high growth restriction factor associated with the addition of Fe, and constitutional supercooling around residual Nb particles, resulting in a near-equiaxed grain structure (average aspect ratio: 2.0) compared to the AS-TNZF (fabricated using the simple scanning strategy). The microstructure consisted of a β-Ti matrix with 2–5 nm sized ω precipitates. Due to the addition of Zr, the transition from β to ω was suppressed during thermal cycling associated with LPBF, resulting in the presence of a partially collapsed ω phase. Without post-processing heat treatments, the AS-TNZF condition exhibited a yield strength (YS) of 1091 MPa, an elastic modulus (E) of 68 GPa, and an elongation (EL) of 16.8%, while the CS-TNZF counterpart achieved a higher YS of 1147 MPa and E of 71 GPa, but a lower EL of 10.8% due to a higher volume fraction of ω phase. Both AS-TNZF and CS-TNZF demonstrated high elastic admissible strain values (YS/E ratio) of 1.60 and 1.62, respectively, achieving high strength, low modulus, and good ductility, which indicates their suitability for biomedical implant materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"64 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systematical characterizations on the microstructure and hardening along depth reveal that the tool tip pressing alone induces no apparent surface deformation and hardening. However, aiding with ultrasound and/or electropulsing achieves a thick deformation layer (&gt;700 μm), significant grain refinement below 7 nm and hardening above 6 GPa. Ultrasound adds extra stress (∼70 MPa) and electropulsing decreases the critical resolved shear stress for generating dislocations and twins, benefiting plastic deformation and grain refinement. Ultrasound and electropulsing allows significant grain refinement without sacrificing surface quality. Additionally, ultrasound and electropulsing promote deformation-induced martensitic transformation. The wide tuning of the deformation and the grain refinement in terms of stress open a window to fabrication of high performance fine-grained materials and surfaces, showing potential scientific and technological importance.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"81 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a novel class of magnetic CoFe/C@bamboo-like carbon nanotubes (BLCNTs) core@shell nanocomposites (CSNCs) were efficiently produced through a simple catalytic decomposition of dicyandiamide (DCD) using CoFe-nitrilotriacetic acid chelate as catalyst precursor. By controlling the amount of DCD, CoFe/C@BLCNTs CSNCs with different BLCNTs contents could be selectively synthesized. The generation of BLCNTs greatly improved the electromagnetic (EM) and EM wave absorption properties (EMWAPs) of CoFe/C. Furthermore, the EM and EMWAPs could be further improved by controlling the pyrolysis temperature. Especially, the optimized CoFe/C@BLCNTs CSNCs exhibited a minimum reflection loss of −21.96 dB at 1.91 mm and an effective absorption bandwidth of 6.80 GHz at 2.27 mm. The acquired results demonstrated that the designed CoFe/C@BLCNTs CSNCs exhibited low density, broadband absorption bandwidth, strong EM attenuation ability, and excellent corrosion resistance, which originated from the excellent magnetic-dielectric synergic, interfacial effect, and generation of BLCNTs.

The results demonstrated that both solid solution treatment and aging treatment improved the mechanical properties of the alloy, while the corrosion resistance of the solid solution-treated alloy was significantly enhanced. The solid solution treatment (340°C) dissolved the fine needle-like α-Mg and AlLi phases, and the Li₂MgAl phase precipitates were dispersed. The ultimate tensile strength of the solution-treated alloy increased significantly from 144 ± 6.2 MPa to 299 ± 1.2 MPa, an increase of almost 107.6%. The high-temperature (225°C) aging treatment made the alloy grain distribution more uniform, caused the AlLi phase particles to gradually coarsen, and transformed the Li₂MgAl phase into a substantial quantity of fine AlLi phase particles. The yield strength increased from 100 ± 5.0 MPa to a maximum of 182 ± 2.6 MPa, representing an approximately 82% increase, while the maximum elongation reached 24.1% ± 2.0%. The electrochemical test results showed that the fine equiaxed grains and uniformly distributed fine needle-like α-Mg phase in the As-built sample reduced micro galvanic corrosion sensitivity and enhanced corrosion resistance compared to the rolled sample. The AlLi phase particles in the solid solution-treated sample were nearly completely dissolved, leading to a significant reduction in micro-galvanic corrosion between the secondary phases and the matrix. Corrosion primarily occurred along the interface between the α-Mg and β-Li phases, exhibiting filamentary corrosion, and the sample showed the highest corrosion resistance. In contrast, the samples subjected to direct high-temperature aging and solution treatment followed by aging exhibited exacerbated local corrosion due to the coarsening of the AlLi phase and the increased amount of precipitation.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"110 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143926608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
