Silica-reinforced Cu matrix composites were fabricated using flake graphite, Cu-coated flake graphite, and Cu-coated expandable flake graphite (denoted as FG, FG-Cu, and EFG-Cu) via powder metallurgy. The microstructure, density, hardness, and compressive strength of the composites were characterized. Their tribological behavior was evaluated using a pin-on-disk tribometer. The results indicate that the copper coating was deposited not only on the surface but also between the layers of the expandable flake graphite, creating an interdigitated structure within the composite. This unique structure significantly enhances interfacial bonding. Consequently, the EFG-Cu composite demonstrated superior properties: Its Brinell hardness (35.8 HBW) and compressive strength (129.33 MPa) were approximately 15 and 29% higher, respectively, than those of the baseline FG composite (31.2 HBW, 100.35 MPa). Furthermore, at a sliding speed of 6 m/s, the EFG-Cu composite exhibited a higher friction coefficient (approximately 0.45) and a substantially lower wear rate (reduced by about 30-40%) compared to the FG and FG-Cu composites.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 25","pages":"25207 - 25215"},"PeriodicalIF":2.6,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148532261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the steel with higher Mn content, the formation of MnO destroys the integrity of Cr₂O₃, and the weakened passive film amplifies the effect of the microstructure. At lower deformation (≤ 30% strain), the increase in low angle and low coincidence site lattice grain boundaries improves the corrosion resistance. The high-density dislocation regions introduce additional active sites, increases the O²⁻/OH⁻ ratio, promotes the formation of a passive film. At higher deformation (50% strain), a large amount of stress concentration and lattice distortion accelerate anodic dissolution and weaken corrosion resistance.

Rietveld refinement demonstrated that Mg inclusion causes a reduction in average crystallite size and nonmonotonically changes in lattice parameters. Also, the average bond length of the [MnO₆] octahedra increased while that of [WO₆] remains almost constant, and the distortion index of both octahedra was reduced. Optically, magnesium doping reduced the band gap nonmonotonically, from 2.83 eV to 2.68 and 2.78 eV for <i>x</i> = 0.05 and 0.1, respectively. The photoluminescence (PL) spectrum manifested a broad emission band in the deep blue–green region (400-520 nm) intensity and the PL intensity obviously dimensioned indicating improved charge carrier separation advantageous for photocatalytic applications. The gamma-ray and neutron shielding efficacy of Mg-doped MnWO₄ was thoroughly assessed for the first time. The doped samples demonstrated increased mass attenuation coefficients (MAC) and linear attenuation coefficients (LAC), with peak values recorded at 15 keV. The radiation protection efficiency (RPE) attained approximately 98.6% at a thickness of 5 cm for the doped samples, surpassing that of regular concrete and commercial glass.

Cold metal transfer (CMT) cladding offers an effective repair method, yet the influence of cladding path strategies on thermal control, residual stress, and deformation remains unclear. This study develops and validates a novel pulsed Gaussian heat source model to capture CMT’s wire feed–retraction characteristics, achieving higher temperature field prediction accuracy than conventional arc models through experimental verification. Four paths—sequential co-direction, cross co-direction, sequential reverse, and cross reverse—are comparatively analyzed via coupled thermal–mechanical simulations and experiments. Cross paths reduce substrate temperatures by ~ 30 °C and residual stresses by 22.0 MPa versus sequential paths. The cross-reverse path yields the lowest deformation, 0.18 mm less than sequential reverse, by alternating deposition directions to limit heat accumulation. X-ray diffraction stress measurements confirm the model’s reliability. Findings provide a validated framework and demonstrate that cross-reverse cladding optimally balances thermal control, stress reduction, and dimensional stability, guiding CMT path optimization for durable boiler tube repair.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 29","pages":"29830 - 29838"},"PeriodicalIF":2.6,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An economic dropwise gelation method, combined with glutaraldehyde crosslinking and freeze-drying, was used to achieve a stable, uniformly dispersed structure. Comprehensive characterization using BET, FTIR, SEM, XRD, and VSM techniques revealed a remarkably high specific surface area of 212 m²/g, a rich presence of –NH₂, –OH, and thiol functional groups with saturation magnetization of 28 emu/g. Batch adsorption experiments revealed maximum adsorption capacities of 598 mg/g for Pb²⁺ and 432 mg/g for Cd²⁺, as determined from Langmuir isotherm fitting (R² &gt; 0.99). Kinetic analysis showed rapid uptake, achieving 90 % of equilibrium capacity within 45 min and fitting a pseudo-second-order model (k₂ = 0.0076 g mg⁻¹ min⁻¹). Thermodynamic analysis confirmed that adsorption was spontaneous (ΔG° &lt; 0) and endothermic (ΔH° &gt; 0), with enhanced randomness at the solid–liquid interface. The beads retained remarkable stability, maintaining 92% (Pb²⁺) and 89% (Cd²⁺) of their initial capacity even after five regeneration cycles. Furthermore, they exhibited excellent operational practicality, achieving over 99% magnetic separation efficiency within only 60 seconds under a 0.5 T external field, underscoring their high recyclability, rapid recovery, and suitability for large-scale, sustainable water treatment applications. In comparison with conventional chitosan–Fe₃O₄ hydrogels (HHBFe), (Pb²⁺: 18.3 mg/g;Cr⁶⁺:3.5 mg/g), the hybrid beads demonstrated an exceptional more than 30-fold enhancement in Pb²⁺ uptake, underscoring the synergistic advantages conferred by the integration of chalcogel. Sustainability evaluation using the Need–Quality–Sustainability (NQS) index revealed superior greenness, blueness, and whiteness scores compared with conventional hybrid beads.
