Evaluation of the Microstructure of Ni-Nb-Si Alloy During Mechanical Alloying

Journal of Advanced Materials in Engineering, 2018
In the present study, the mechanical alloying process was used to produce the Ni-Nb-Si amorphous alloy. X-ray diffraction (XRD)analysis and high-resolution transmission electron microscopy (HRTEM) were used to approve the amorphous phase formation after ...

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Effect of biphasic interface on mechanical properties and deformation mechanism of nickel base alloy

Journal of Materials Research and Technology
The tensile properties of biphasic nickel-based nanopolycrystalline alloys (Ni–Ni3Al) at different temperatures were simulated by molecular dynamics. The results show that the tensile properties of the dual-phase nano-polycrystalline alloy are obviously ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

The Ni,Cd Heteroatoms‐Initiated Synergistic Tuning of Electron Configuration in Fe2VO4 Nanosheets Electrocatalysts to Profoundly Stabilize Alkaline Seawater Electrolysis

Advanced Functional Materials, EarlyView.
A Ni,Cd‐codoped Fe2VO4/NF bifunctional electrocatalyst is rationally designed for efficient seawater electrolysis. Synergistic effect modulates electron configuration, optimizes intermediates adsorption, stabilizes high‐valence Fe/V sites, and repels chloride ions to suppress corrosion and side reactions, thus contributing to performance improvement of
