In this work, the 2 wt.% Ti particle reinforced Mg-6 Zn alloy composites with different contents (0, 0.5, 1, 1.5, 2 wt.%) of Mn were prepared using semi-solid stirring assisted ultrasonic treatment followed by hot extrusion. With the increment of Mn element, the characteristics of mixed-grain structure became obvious and the DRX was inhibited. Meanwhile, the interfacial product gradually changed from MgZn₂ to Mn₂Ti. The tensile test demonstrated that the 2Ti/Mg-6Zn-1.5Mn composite exhibited an excellent strength-ductility synergy, achieving the highest yield stress (YS), ultimate tensile stress (UTS) of 239 MPa, 366 MPa, respectively, along with a notable elongation (El.) of 20.6%. The increased strength is mainly due to the grain refinement, the precipitation strengthening, the HDI strengthening and the strong interfacial bonding including the tightly Ti/Mn₂Ti bonding and the Mn₂Ti/Mg coherent orientation relationship. The ideal El. is the result of fine/coarse bimodal structure and the proper interfacial reaction, which can reduce the occurrence of cracks.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"60 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143878023","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}

A dual-strategy approach integrating in-situ host–guest nanoconfinement and surface self-assembly was devised to fabricate 8HQ@ZIF-8/PDA smart nanocontainers. The guest 8-hydroxyquinoline (8HQ) was encapsulated within the zeolitic imidazolate framework-8 (ZIF-8) host, leveraging nanoconfinement effects. A bioinspired polydopamine (PDA) layer was then self-assembled on the 8HQ@ZIF-8 surface through dopamine oxidative self-polymerization, resulting in a robust nanocontainer architecture. Density functional theory (DFT) calculations verify that the molecular interactions between the PDA and the ZIF-8 surface was the chemical adsorption. The resultant 8HQ@ZIF-8/PDA retained the rhombic dodecahedral morphology and crystallinity of ZIF-8, demonstrating controlled pH-responsive release behavior. When incorporated into an epoxy (EP) resin matrix on magnesium alloy, the 8HQ@ZIF-8/PDA/EP smart composite coatings exhibited outstanding interfacial compatibility and long-term stability, achieving a low-frequency impedance (|<em>Z</em>|₀.₀₁_Hz) of 2.49 × 10⁷ Ω cm², a maximum phase angle of 82.8°, and a breakpoint frequency (<em>f</em>_b) of 63.34 Hz after 50 days of immersion in a 3.5 wt% NaCl solution.

However, Mg metal anodes face several challenges, notably the natively existence of an inactive oxide layer on their surfaces, which reduces their effectiveness. Additionally, interactions of Mg electrodes with electrolyte solutions’ components can lead to the formation of insulating surface layers, that can fully block them for ions transport. This review addresses these issues by focusing on surface treatments strategies to enhance electrochemical performance of Mg anodes. It highlights chemical and physical modification techniques to prevent oxidation and inactive-layers formation, as well as their practical implications for MIBs. We also examined the impact of Mg anodes’ surface engineering on their electrochemical reversibility and cycling efficiency. Finally, future research directions to improve the performance and commercial viability of magnesium anodes and advance development of high-capacity, safe, and cost-effective energy storage systems based on magnesium electrochemistry are discussed.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"17 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876465","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}

FSP induced complete dissolution of the coarse Mg5(Gd,Y) eutectic network (initial size: 3.3 ± 0.5 µm) and triggered dynamic recrystallization, achieving a 69.5% grain refinement from 16.4 µm (WAAMed) to 5.0 µm (FSPed). This microstructural transformation enhanced ultimate tensile strength (UTS) by 32% (217 ± 3 MPa → 286 ± 2 MPa), yield strength (YS) by 46% (124 ± 2 MPa → 182 ± 7 MPa), and elongation (EL) by 35% (9.7 ± 1.1% → 13.1 ± 1.4%). Quantitative analysis via Hall-Petch relationship confirmed that grain refinement contributed ∼50 MPa (79%) of the total YS increment, while nano-precipitation (β′′/β′ phases &lt;20 nm) effects accounted for the remaining ∼13 MPa. The simultaneous strength-ductility enhancement originates from FSP-induced defect elimination (porosity reduction: 1.75% → 0.18%) and dual-phase grain boundary pinning by Zr particles and β-Mg₅(Gd,Y) precipitates.

Atomic-scale modeling, typically using ab-initio or semi-empirical approaches, has mainly focused on GB segregation at highly symmetric GBs in Mg alloys, often failing to capture the diversity of local atomic environments and segregation energies, resulting in inaccurate structure-property predictions. This study employs atomistic simulations and machine learning models to systematically investigate the segregation behavior of common solute elements in polycrystalline Mg at both 0 K and finite temperatures. The machine learning models accurately predict segregation thermodynamics by incorporating energetic and structural descriptors. We found that segregation energy and vibrational free energy follow skew-normal distributions, with hydrostatic stress, an indicator of excess free volume, emerging as an important factor influencing segregation tendency. The local atomic environment’s flexibility, quantified by flexibility volume, is also crucial in predicting GB segregation. Comparing the grain boundary solute concentrations calculated via the Langmuir-McLean isotherm with experimental data, we identified a pronounced segregation tendency for Nd, highlighting its potential for GB engineering in Mg alloys. This work demonstrates the powerful synergy of atomistic simulations and machine learning, paving the way for designing advanced lightweight Mg alloys with tailored properties.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"4 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866199","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}

Magnesium alloys with varying compositions of aluminum (Al), tin (Sn), Zn, and Na were prepared and aged at 453 K. Microstructural analyses were conducted using transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), and atom probe tomography (APT). Trace additions of Na significantly enhanced the precipitation responses of both Mg₁₇Al₁₂ and Mg₂Sn phases. When Zn was co-added with Na, as in the ATZ641N3 alloy (Mg–6Al–4Sn–1Zn–0.3Na), there was a pronounced refinement in precipitate morphology and acceleration of precipitation kinetics. The ATZ641N3 alloy achieved a peak hardness of 103 Hv at 36 hours, compared to 91 Hv at 72 hours for the ATZ641 alloy without Na. The simultaneous addition of Zn and Na led to the formation of Sn–Na–Zn particles that acted as effective nucleation sites for Mg₂Sn, promoting aluminum partitioning and accelerating the precipitation of Mg₁₇Al₁₂ through Al-rich regions. Additionally, Zn and Na co-segregated within the Mg₁₇Al₁₂ phase, reducing misfit strain caused by Zn substitution and improving precipitate stability and refinement. These findings highlight Zn's critical role, alongside trace Na additions, in refining and accelerating the precipitation of Mg₁₇Al₁₂ and Mg₂Sn phases, thereby enhancing the age-hardening response of magnesium alloys.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"7 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862278","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}

The initial microstructure of the precursor significantly influences dealloying kinetics and phase transitions. The single-phase Ti₅₀Cu₅₀ precursor exhibits a faster initial dealloying rate due to its homogeneous structure, yet complete dealloying requires 90 min. In contrast, the dual-phase Ti₃₀Cu₇₀ precursor achieves complete dealloying in 30 min, demonstrating the impact of a higher Cu concentration on accelerating the process kinetics. Additionally, the study explores the coarsening behavior and hardness variations during the LMD process, along with the microstructural characteristics of Mg-Ti composites fabricated from these two precursors.
