Influence of thickness ratios on the coordinated deformability of heterogeneous metals and interface toughness under the action of temperature gradient and shear force was investigated. Results show that the relative deformation rates of matrix and composite materials converge gradually under the influence of work hardening of Mg/Al layer. The Mg layer is mainly DRXed grains and texture intensity gradually weakens with increasing thickness ratio. The Al layer is mostly dominated by subgrains and deformed grains, which have a strong correlation with thickness ratio. Strength and plasticity of composites first increase and then decrease with increasing thickness ratio. Fracture of composite plate occurs in intermetallic compounds (IMCs). Thickness of IMCs has a strong positive correlation with thickness ratio. When the thickness ratio of AZ31B/Al6061 for 5, the relative thickness of IMCs is the largest and the relative bonding strength is the smallest.

The active prismatic dislocation slip within refined grains was due to its much lower relative activation stress to basal slip (CRSS<em>_prism</em>/ CRSS<em>_basal</em> of only ∼1.6) owing to the effective grain boundary hardening.

The effect of NbB₂ particles on the microstructural evolution of the AZ91 alloy was investigated. The presence of NbB₂ was shown to have a grain-refining effect on the AZ91 alloy and promoted dynamic recrystallization (DRX) and precipitation of fine Mg₁₇Al₁₂ phases via particle-stimulated nucleation (PSN). Tensile testing revealed substantial enhancements in the ultimate tensile strength (UTS), yield strength (YS), and elongation (EL) of the as-rolled AZ91 alloy, with values of 379 MPa, 292 MPa, and 14.7 %, respectively, owing to the incorporation of NbB₂ particles. Annealing led to further enhancements in EL with slight reductions in UTS and YS (360 MPa, 252 MPa, and 16.8 %, respectively). Owing to grain refinement and the PSN effect of the NbB₂ particles, a significant number of geometrically necessary dislocations (GNDs) were induced in the matrix during the rolling process, which reduces the nucleation barrier and increases the number of nucleation sites for the recrystallized grains and Mg₁₇Al₁₂ precipitates. Meanwhile, many residual dislocations and fine Mg₁₇Al₁₂ precipitates in the as-rolled alloys were annihilated during annealing, resulting in slight grain growth and coarsening. The strengthening mechanism of the NbB₂/AZ91 composite are mainly associated with grain-refinement strengthening, particle-induced dislocation strengthening, strengthening resulting from mismatching coefficients of thermal expansion (CTE), and hetero-deformation-induced (HDI) strengthening. Textural weakening, increased activation of non-basal slip systems, more-uniform strain patterns resulting from NbB₂ particles, and precipitation are mainly responsible for enhancing ductility.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"77 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142363256","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}

Significant research has been focused on enhancing the performance of AZIBs, but challenges persist. Vanadium-based oxides, known for their large interlayer spacing, are promising cathode materials. In this report, we synthesize Mg²⁺-intercalated potassium vanadate (KVO) (MgKVO) via a single-step hydrothermal method and achieve a 12.2 Å interlayer spacing. Mg²⁺ intercalation enhances the KVO performance, providing wide channels for Zn²⁺, which results in high capacity and ion diffusion. The combined action of K⁺ and Mg²⁺ intercalation enhances the electrical conductivity of MgKVO. This structural design endows MgKVO with excellent electrochemical performance. The AZIB with the MgKVO cathode delivers a high capacity of 457 mAh g^-1 at 0.5 A g^-1, excellent rate performance of 298 mAh g^-1 at 5 A g^-1, and outstanding cycling stability of 102% over 1300 cycles at 3 A g^-1.
