However, hot cracks are prone to occur during welding nickel-based superalloys, which can seriously damage the structural integrity, load-bearing capacity, fatigue life, and overall safety of welded components. Therefore, this article systematically reviews the composition classification system of nickel-based superalloys and the current application of welding techniques such as fusion welding, solid phase welding, and brazing in nickel-based superalloys. It also provides an in-depth analysis of common hot cracking issues during nickel-based superalloy welding. This analysis includes the formation mechanisms of solidification cracking, liquation cracking, and ductility-dip cracking, as well as the influence of important factors such as element segregation, thermal stress concentration, and grain boundary weakening on hot cracking. In addition, this paper also sorts out the susceptibility test methods of hot cracking in nickel-based superalloys. This review provides a solid theoretical basis and technical support for the development of new nickel-based superalloy welding technology, hot cracking susceptibility test methods, and the exploration of more effective hot cracking suppression strategies.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 42","pages":"20216 - 20266"},"PeriodicalIF":3.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341358","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}

This study addresses these challenges by exploring the potential of sulfur-doped biomass carbon as a promising anode material for SIBs. Using a molten salt method with a Na₂SO₃@LiCl/KCl system, sulfur was introduced into biomass carbon to significantly improve its electrochemical properties. The sulfur doping enhanced the material’s conductivity, created additional active sites, and facilitated sodium-sulfur (Na–S) reactions, which contributed to superior electrochemical performance. The high sulfur doped hard carbon (HS-HC) electrode exhibited exceptional rate capability, retaining high specific capacity at elevated current densities, and demonstrated remarkable cycling stability with a capacity retention of 95% after 3100 cycles. These findings not only highlight the potential of sulfur-doped biomass carbon for improving the performance of SIBs but also offer a sustainable and cost-effective solution for next-generation energy storage systems.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 41","pages":"19883 - 19895"},"PeriodicalIF":3.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315796","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 membrane, denoted as PU–PVDF/TiO₂, incorporates polyvinylidene fluoride (PVDF) as in situ polarization adsorption with PU as enhancement of mechanical strength and titanium dioxide (TiO₂) as a photocatalyst for antimicrobial functionality. The electret filtration performance, mechanical properties, and antibacterial activity of the membrane were systematically characterized using SEM, XRD, FTIR, filtration tests, and density functional theory (DFT) simulations. Novelly, DFT modeling was employed to elucidate the mechanisms of the self-polarization effect and the reinforcement role of PU. Results indicate that the addition of PU significantly improves the mechanical performance of the PVDF membrane, achieving a tensile strength of 6.59 MPa and a 27.2% increase in elongation at break, with only a minor rise in air resistance. Meanwhile, TiO₂ not only provides photocatalytic antibacterial activity but also facilitates the β-phase crystal transformation in PVDF, thereby enhancing filtration efficiency and reducing pressure drop—resulting in 97.3% efficiency for PM_1.0 and a low resistance of 31.8 Pa. Additionally, the incorporation of TiO₂ contributed to a reduction in average fiber diameter from 366 to 258 nm. The membrane exhibited an antibacterial efficiency of 99.9% against <i>Staphylococcus aureus</i>.
