Corrosion Behavior of Commercial FeCrAl and TiAl Alloys in Molten Pb With 2E‐7 wt% Oxygen at 600°C and 700°C

Materials and Corrosion, EarlyView.
Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.

Corrosion Performance of Steel and Zinc‐Based Materials in Diverse Unsaturated Soils: Insights From a 2‐Year Field Exposure

Materials and Corrosion, EarlyView.
The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability

High‐Temperature Corrosion of Unpassivated Carbon Steel in Simulated Boiler Water: Electrochemical Thresholds and Mechanisms for Chloride and Sulphate Contamination

Materials and Corrosion, EarlyView.
Through a combination of in situ electrochemical corrosion rate measurements and FactSage thermochemistry modeling, chloride and sulphate ions were found to influence the corrosion of carbon steel in high‐temperature boiler water through distinct mechanisms: chloride acidifies the solution, raising iron solubility, while sulphate leaves solubility ...

Origin of the magnetite boundary in the Peninsular Ranges batholith, southern California, U.S.A., and Baja California, Mexico

Revista Mexicana de Ciencias Geológicas, 2019
In the Peninsular Ranges of southern California, U.S.A., and Baja California, Mexico, the Cretaceous granitic rocks to the southwest, nearly all of which contain magnetite, adjoin Cretaceous granitic rocks to the northeast, nearly all of which are ...

Long‐Term Corrosion of Carbon‐Steel Casing Used in Deep Geological Radioactive Waste Repository

Materials and Corrosion, EarlyView.
Fifty mots 6‐year study of carbon steel corrosion in a deep geological repository (Bure, France). Three corrosion patterns were identified, driven by local conditions. Minimal corrosion layer thickness growth suggests limited corrosion progression under most conditions.

Determining the effective use of magnetite in lipid-magnetite suspensions

Eastern-European Journal of Enterprise Technologies, 2014
Доведено ефективність використання магнетиту в ліпідо-магнетитових суспензіях в якості дисперсійної фази, що забезпечує необхідні властивості: стійкість у часі, дисперсність та концентрацію. В якості дисперсійного середовища застосовувалися рослинні масла: кукурудзяне, соєве та соняшни-кове; в якості поверхнево-активної речовини (ПАР ...

Color Alleviation in Hybrid Electrospun‐Electrosprayed Magnetic Paper

Macromolecular Rapid Communications, EarlyView.
A combined electrospinning/electrospraying fabrication approach enables the chromatic alleviation of the brown Color of Fe3O4 nanoparticles, by encapsulating them within polymer‐based electrosprayed microparticles that are sandwiched between electrospun fibrous layers.

Particle‐Scale Mechanics of a Regolith‐Type Soil

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The existing studies have reported that the surface of Mars shows the presence of materials having igneous origin, including basalt and regolith‐type coarse soils. These findings are affected by significant uncertainties and, therefore, the selection of simulants for various exploration applications, including surface mobility of rovers ...

Complexions at the iron-magnetite interface

Nature Communications
Abstract Synthesizing distinct phases and controlling crystalline defects are key concepts in materials design. These approaches are often decoupled, with the former grounded in equilibrium thermodynamics and the latter in nonequilibrium kinetics.

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

Polymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...
