Brute Force Composition Scanning with a CALPHAD Database to Find Low Temperature Body Centered Cubic High Entropy Alloys

Entropy, 2018
We used the Thermo-Calc High Entropy Alloy CALPHAD database to determine the stable phases of AlCrMnNbTiV, AlCrMoNbTiV, AlCrFeTiV and AlCrMnMoTi alloys from 800 to 2800 K. The concentrations of elements were varied from 1⁻49 atom%.

Microstructure and properties of AlCrFeNiMoNb high-entropy alloys coating on ZM5 magnesium alloy prepared by high-velocity air fuel (HVAF) spray

Journal of Materials Research and Technology, 2023
AlCrFeNiMoNb high-entropy alloys were successfully coated onto a ZM5 alloy using high-velocity air fuel spray (HVAF). Microcomputed tomography(micro-CT) results revealed that the porosity of the coating was only 0.36%, which demonstrates the coating has ...

Electron Redistribution Drives Structural Ordering in Sulfate (SO4) Adlayers

ChemElectroChem
In this work, the coadsorption of SO4 and H2O at the Au(111)‐electrolyte interface is investigated. It is uncovered how electron redistribution between coadsorbates correlates with the formation of tightly packed (√3a) SO4‐adsorbate chains, which have ...

Developing novel high-Si 12 % Cr reduced-activation ferritic/martensitic cladding alloys via the cluster-formula approach and CALPHAD method

Materials & Design
The corrosion-resistance in lead–bismuth eutectic (LBE) coolant at elevated temperatures of traditional reduced-activation ferritic/martensitic (RAFM) steels could not meet the requirements for the application of fuel claddings.
