Herein, we demonstrate that, in 1 M Zn(CF<sub>3</sub>SO<sub>3</sub>)<sub>2</sub>/DMF (N, N-dimethylformamide) electrolyte, confining oxygen in carbon cathode materials via high-energy ball milling can synergistically introduce additional pseudocapacitance on the cathode side while suppressing the dendrite growth on Zn anode side, which jointly lead to high energy density (94 Wh kg<sup>−1</sup> at 448 W kg<sup>−1</sup>) and long cycle stability of ZICs.

Prussian blue analogues (PBAs) are considered as the highly promising cathode materials for AZIBs because of their low cost and high voltage potential. Its excellent electrochemical performance and sustainable energy storage capability provide a new direction and opportunity for the development of AZIBs technology. The practical application of PBAs in AZIBs, however, is restrained by its unstable cycle life deriving from PBAs’ inherent structure deficiencies and its dissolution in aqueous electrolyte. Based on the summary of series of literature, we will comprehensively introduce the PBAs as cathodes for AZIBs in this review. Firstly, some basic knowledge of PBAs is introduced, including structural characteristics, advantages and issues. Secondly, several commonly used modification methods to improve the properties of PBAs, as well as electrolytes to stabilize PBAs, are presented. Finally, the future research directions and commercial prospects of PBAs in AZIBs are proposed to encourage further exploration and promote technological innovation.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"81 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142449849","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}

This integration was accomplished using a combined chemical co-deposition method and redox reaction. Furthermore, a uniform and controllable Se/β-CS coating was applied to the K-wire's surface using the Langmuir-Blodgett technique.

This study utilized focused ion beam and digital image correlation (FIB-DIC) techniques to assess residual stress within the dendrite stem and arm of nickel-based single-crystal superalloys. The influence of hot isostatic pressing (HIP) on the microstructure and residual stress was also elucidated. Our results revealed that the residual stresses in the dendrite stem and arm regions manifest as tensile stress along the <em>x</em>-axis and compressive stress along the <em>y</em>-axis, with a range of -720 MPa to 680 MPa. HIP treatment effectively improved microstructure and regulated residual stress in nickel-based single-crystal superalloys, leading to a rapid reduction in residual stress levels. The present study lays a solid theoretical groundwork for optimizing processing strategies to regulate residual stress and enhance mechanical properties in next-generation single-crystal superalloys.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"107 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142450295","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}

However, the complex relationship between precipitates and two-stage aging process presents a significant challenge for the optimization of process parameters. In this study, machine learning models were established based on orthogonal experiment to mine the relationship between two-stage aging parameters and properties of Cu-5.3Ni-1.3Si-0.12Nb alloy with preferred formation of DPs. Two-stage aging parameters of 400 °C/75 min + 400 °C/30 min were then obtained by multi-objective optimization combined with an experimental iteration strategy, resulting in a tensile strength of 875 MPa and a conductivity of 41.43 %IACS, respectively. Such an excellent comprehensive performance of the alloy is attributed to the combined precipitation of DPs and CPs (with a total volume fraction of 5.4% and a volume ratio of CPs to DPs of 6.7).

It is a need to explore more efficient and expedited methods to design magnesium alloys with high modulus and ductility. In this study, machine learning (ML) and assisted microstructure control methods are used to design high modulus magnesium alloys. Six key features that influence stiffness and ductility have been extracted in this ML model based on abundant data from literature sources. As a result, predictive models for Young's modulus and elongation are established, with errors less than 2.4% and 4.5% through XGBoost machine learning model, respectively. Within the given range of six features, the magnesium alloys can be fabricated with the Young's modulus exceeding 50 GPa and an elongation surpassing 6%. As a validation, Mg-Al-Y alloys were experimentally prepared to meet the criteria of six features, achieving Young's modulus of 51.5 GPa, and the elongation of 7%. Moreover, the SHapley Additive exPlanation (SHAP) is introduced to boost the model interpretability. This indicates that balancing the volume fraction of reinforcement, the most important feature, is key to achieve Mg-Al-Y alloys with high Young's modulus and favorable elongation through the two models. Enhancing reinforcement dispersion and reducing the size of reinforcement and grain can further improve the elongation of high-stiffness Mg alloy.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"7 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142449852","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 series of novel high-entropy alloys (HEAs) (FeCoCrNiMo<em>_x</em>Nb<em>_x</em>) with exceptional corrosion resistance were designed. The phase composition, corrosion resistance, and passive film properties were determined through micro-characterization and electrochemical tests. First-principles calculations were further performed to unveil the corrosion resistance mechanism at the atomic level, especially the influence of elements on the corrosion resistance. It is found that the appropriate increase in the contents of Mo/Nb elements leads to the increased Laves phase in the HEAs and enhances the corrosion resistance of the HEAs. However, the excessive addition of Mo/Nb elements will cause more severe microgalvanic corrosion between FCC and Laves phases, resulting in a decrease in corrosion resistance. Theoretical calculations demonstrate that the Laves phase is more resistant to the attack of corrosive species. Additionally, the presences of Mo, Nb, and Cr elements in the HEAs facilitate the adsorption of H₂O/O on the HEAs surface, which promotes the formation of a protective passive film, and then provides better protection for the HEAs.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"1 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448425","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}
