The NBFS was modified through a dual process involving nanoscale transformation and hydration with water (20 wt.%) for 7 days, enhancing its surface area and reactivity. The hydrated NBFS was characterized using XRF, SEM, EDS, FTIR, and XRD techniques, revealing its amorphous to crystalline transformation and the presence of OH<sup>−</sup> as a functional group. Batch adsorption experiments were conducted to optimize the parameters of adsorbent dosage, pH, contact time, initial ion concentration, and temperature. The results demonstrated remarkable removal efficiencies of 99.4% for Fe, 96.2% for Cu, and 93.7% for Zn at an optimal pH of 6, a contact time of 90 min, and a temperature of 70 °C. The adsorption process followed pseudo-second-order kinetics and the Langmuir isotherm model, indicating a chemisorption mechanism with monolayer coverage. Thermodynamic studies confirmed that the adsorption process was spontaneous. Additionally, the hydrated NBFS exhibited excellent reusability, maintaining a high removal efficiency over five consecutive adsorption-desorption cycles.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 11","pages":"8534 - 8547"},"PeriodicalIF":2.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-025-07692-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data for training are generated through atomistic simulations. In ML models, each chemical composition is encoded as a five-dimensional numerical vector to facilitate the representation of features, which are then normalized to balance the input scales during model training. Although explicit inter-composition connections are not included, the models learn compositional trends through node features and internal attention mechanisms. Because the lattice parameter is a byproduct in calculating the USFE in atomistic simulations, we also build three models for the lattice parameters. All models achieve reasonable accuracy in predicting lattice parameters but show variability in USFE predictions. Among the three models, GAT achieves the highest accuracy with average errors of 0.68% for USFE and 0.09% for the lattice parameter, outperforming GNN (1.24%, 0.11%) and XGBoost (0.46%, 0.54%).

Efficient impurity removal with minimal losses of valuable metals is essential for effective PLS purification. This study investigates the effect of CaCO<sub>3</sub> particle size (− 400 mesh) on precipitation performance, revealing an 11% improvement in aluminum removal efficiency compared to coarser particles. A two-stage precipitation process was found to be optimal. In the first stage (80°C, pH 3.0, 2 h), 96% Fe, 92% Al, and 97% Cr were removed, with minimal co-precipitation of Ni (1.04%) and Co (2.05%). The second stage (70°C, pH 4.5, 1.5 h) achieved 99.9% removal of Fe, Al, and Cr, though with slightly higher Ni loss (3.95%). Morphological analysis revealed that CaCO<sub>3</sub> produced crystalline residues, facilitating improved solid-liquid separation compared to the amorphous residues formed using NaOH and MgO. The thermogravimetric analysis confirmed superior moisture control in CaCO<sub>3</sub>-derived residues, showing only 2.88% mass loss at 115°C, significantly lower than residues from MgO and NaOH. These results provide practical guidance for impurity removal in HPAL operations and highlight the effectiveness of CaCO<sub>3</sub> as a neutralizing agent.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 10","pages":"7461 - 7475"},"PeriodicalIF":2.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079002","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}

The study demonstrated that optimal welding parameters, including an interlayer thickness of 0.4 mm and a beam offset distance of 0.2 mm, resulted in joints with superior tensile strength and defect-free weld morphology. Adjustments to interlayer thickness and beam positioning effectively controlled the melting extent of the TZM base material, thereby regulating the Mo content within the weld and suppressing the formation of brittle intermetallic compounds. Detailed microstructural analysis revealed that fine eutectic structures within the reaction layer played a crucial role in improving the performance of the joints, while excessive interlayer thickness or improper beam offset compromised mechanical integrity.

However, forming processes significantly affect the material's microstructure, which in turn influences its corrosion behavior. Depending on the chemical composition and forming history, 316L tends to martensite formation during forming, which strongly impacts the corrosion behavior in narrow zones close to the surface. In forming processes with tool contact, local martensite formation occurs at least on the surface up to a few micrometers into the bulk of the material. The residual stress state, phase fractions, crystallite sizes and microstrain are experimentally determined by x-ray diffraction and numerically predicted. This paper introduces a numerical approach to predict corrosion rates of 316L after cold rolling. The method extends conventional forming simulations with empirically calibrated models that factor in the component surface and the near-surface microstructure. This approach facilitates the optimization of workpiece designs and forming processes and is also adaptable to other materials and forming operations.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 10","pages":"7529 - 7539"},"PeriodicalIF":2.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-025-07661-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
