However, the important precursor, namely Cu_1/9Ni_2/9Fe_1/3Mn_1/3 (denoted as C1N2F3M3), for preparing NaC1N2F3M3 cathode materials is usually prepared through traditional one-step co-precipitation process in industry, which generally affords a low tap density (TD) C1N2F3M3 precursor, and the low TD of the precursor has adverse effects on the electrochemical performance of final cathode materials. In this study, a high TD precursor, C1N2F3M3-H, with a NiFeMn@Cu core–shell structure was prepared by a two-step synthetic procedure. The TD of C1N2F3M3-H is 1.86 g/cm³, which is enhanced by 75% compared with that of C1N2F3M3-L. Importantly, the NaC1N2F3M3-H cathode material prepared from C1N2F3M3-H displays an evidently improved electrochemical performance in the assembled sodium-ion battery compared to NaC1N2F3M3-L prepared from C1N2F3M3-L. The first discharge specific capacity and coulombic efficiency of NaC1N2F3M3-H are 135.34 mAh g⁻¹ and 98.7% in the voltage range of 2.50–4.05 V at 0.1 C. After 100 cycles at 1 C, the capacity retention rate is 89.88%, which is higher than 80.82% for NaC1N2F3M3-L. Moreover, the electrochemical dynamics analysis shows that the NaC1N2F3M3-H electrode has faster Na⁺ diffusivity and lower charge transfer resistance compared to the NaC1N2F3M3-L electrode, indicating that the NaC1N2F3M3-H has better rate performance and higher conductivity. This study develops a two-step method for preparing the high TD precursor containing quaternary metal-oxide components, from which high-performance cathode materials can be obtained.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 15","pages":"6642 - 6656"},"PeriodicalIF":3.5,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875413","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}

Heterogeneous intragranular deformation caused by the operation of octahedral and partial slip systems causes rapid grain fragmentation without significant change in aspect ratio. The grain size was reduced from nearly 26 μm, as measured by EBSD, to approximately 59 nm after five turns, as determined by TEM, accompanied by a significant increase in hardness after the first turn, with saturation observed up to five turns. Nanoindentation experiments indicated that the improvement in strength was accompanied with substantial plasticity indicated by the plasticity index <i>W</i>_p/<i>W</i>_t during nanoindentation unloading cycle. This is followed by a decrease in strain rate sensitivity and marginal decrease in activation volume till a shear strain of about <i>ε</i>_vm ≈ 29, after which both remain almost constant indicating a steady state of microstructural refinement. Microstructural analyses, including EBSD and TEM, confirmed that grain subdivision occurs through dislocation rearrangement, leading to the formation of low-angle grain boundaries that progressively transform to high-angle grain boundaries contributing to grain size refinement by grain subdivision with the increase in strain. The process of grain refinement does not involve nucleation of dislocation free grains as observed for classical discontinuous recrystallization and is attributed to continuous dynamic recrystallization (CDRX) or extended dynamic recovery. Thus, the FeMnNi medium entropy alloy exhibits scope for microstructural engineering in the ultrafine and nanocrystalline regime to achieve optimum combination of strength and ductility.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 15","pages":"6688 - 6714"},"PeriodicalIF":3.5,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875369","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 incorporation of thermoplastic polyimide (PI) into thermosetting resins is an effective strategy for enhancing toughness. The phase separation mechanisms of PI within the resin matrix have been extensively studied. However, the majority of studies have concentrated on epoxy, and research on BMI is limited. Moreover, compared with factors such as the content and structural composition of the modifier PI, the molecular weight is often overlooked. In this work, a tailored series of fluorine polyetherimides (abbreviated as PI-X) with weight-average molecular weights (<i>M</i>_w) ranging from 1.5 to 3.6 × 10⁴ were synthesized using an in situ prepolymerization method. In this method, the basic modifier of BMI, ortho-diallyl bisphenol A (DABPA) was used as a solvent to synthesize a PI-X solution; here, the process was simplified and met the requirement of green chemistry with no pollutant emissions. The novel PI-X contains fluorine elements, ether bonds and asymmetric structures; these bonds and structures are beneficial for synergistically improving toughness and high-temperature resistance. By maintaining a constant concentration of 4 wt% DABPA, the effects of the PI-X molecular weight on the phase separation and performance of the PI-X/BMI/DABPA system (BDP) were investigated in detail. Notably, the impact strength and flexural strength of the BDP resins showed significant improvements, reaching 30.1 kJ/m² and 157.7 MPa, respectively, which were 67.2% and 16.1% greater than those of pure BDP. Additionally, the thermal stability was enhanced, with a 9.8 °C increase in the <i>T</i>_g when the molecular weight of PI-X was approximately 2.5 × 10⁴. Based on Flory lattice model, the influence of BMI curing degree on PI-X compatibility and phase separation mechanism was explored. As the molecular weight increased, the compatibility between PI-X and BMI gradually deteriorated. This led to pronounced phase separation and the formation of spherical PI-X particles, which impacted the overall performance.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 15","pages":"6749 - 6768"},"PeriodicalIF":3.5,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875439","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}
