As the demand for lightweight structures in the transportation industry continues to rise, AA5083 aluminum alloy has become increasingly prominent due to its superior corrosion resistance and weldability. To facilitate the production of high-quality, intricate AA5083 components, 5087 aluminum filler wire is commonly utilized in metal inert gas (MIG) welding processes for industrial applications. The optimization of filler wire composition is critical to enhancing the mechanical properties of AA5083 MIG-welded joints. This study investigates the effects of modifying 5087 aluminum filler wires with different titanium (Ti) contents on the microstructure and weldability of AA5083 alloy plates using MIG welding. The influence of Ti contents was systematically analyzed through comprehensive characterization techniques. The findings reveal that the constitutional supercooling induced by the Ti element and the formation of Al₃Ti facilitate the heterogeneous nucleation of α(Al), thereby promoting grain refinement. When the Ti content of 5087 filler wire is 0.1 wt.%, the grain size of the weld center was 78.48 μm. This microstructural enhancement results in the improved ductility of the AA5083 MIG-welded joints, with a maximum elongation of 16.64% achieved at 0.1 wt.% Ti addition. The hardness of the joints was the lowest in the weld center zone. This study provides critical insights into the role of Ti content in MIG welding and contributes to the advancement of high-performance filler wire formulations. Full article

In order to address the issues of energy depletion, more resources are being searched for in the deep sea. Therefore, research into how the deep-sea environment affects cement-based materials for underwater infrastructure is required. This paper examines the impact of ocean depth (0, 500, 1000, and 1500 m) on the ion interaction processes in concrete nanopores using molecular dynamics simulations. At the portlandite interface, the local structural and kinetic characteristics of ions and water molecules are examined. The findings show that the portlandite surface hydrophilicity is unaffected by increasing depth. The density profile and coordination number of ions alter as depth increases, and the diffusion speed noticeably decreases. The main cause of the ions’ reduced diffusion velocity is expected to be the low temperature. This work offers a thorough understanding of the cement hydration products’ microstructure in deep sea, which may help explain why cement-based underwater infrastructure deteriorates over time.

Abstract

A zinc supracluster [Zn₂₄(ATZ)₁₈(AcO)₃₀(H₂O)_1.5]·(H₂O)_3.5 (Zn₂₄), and a 1D zinc supracluster chain {[Zn₂₄(ATZ)₁₈(AcO)₃₀(C₂H₅OH)₂(H₂O)₃ [...] Read more.

A zinc supracluster [Zn₂₄(ATZ)₁₈(AcO)₃₀(H₂O)_1.5]·(H₂O)_3.5 (Zn₂₄), and a 1D zinc supracluster chain {[Zn₂₄(ATZ)₁₈(AcO)₃₀(C₂H₅OH)₂(H₂O)₃]·(H₂O)_2.5}_n (1-D⊂Zn₂₄) with molecular diameters of 2 nm were synthesized under regulatory solvothermal conditions or the micro bottle method. In an N,N-dimethylformamide solution of Zn₂₄, Fe³⁺, Ni²⁺, Cu²⁺, Cr²⁺ and Co²⁺ ions exhibited fluorescence-quenching effects, while the rare earth ions Ce³⁺, Dy³⁺, Er³⁺, Eu³⁺, Gd³⁺, Ho³⁺, La³⁺, Nd³⁺, Sm³⁺, and Tb³⁺showed no obvious fluorescence quenching. In ethanol solution, the Zn₂₄ supracluster can be used to selectively detect Ce³⁺ ions with excellent efficiency (limit of detection (LOD) = 8.51 × 10⁻⁷ mol/L). The Zn₂₄ supracluster can also detect wavelengths between 302 and 332 nm using the intensity of the emitted light. Full article
