Corrosion Behavior of Magnesium Alloys in Alkaline Solutions Simulating a Low‐Level Radioactive Waste Repository

Materials and Corrosion, EarlyView.
The corrosion rates of two types of magnesium alloys in an alkaline solution containing crushed ordinary Portland cement paste grains decreased with increasing immersion time. This decrease was attributed to the formation of a protective layer containing brucite and hydrotalcite on the specimen surfaces.

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 ...

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Overlap Percentage Effects on Microstructure and Microhardness in Wire Arc Additive Manufacturing of AISI 308L Stainless Steel

MetalMat, EarlyView.
Overlap percentage governs the remelting, dilution, and solidification behavior of CMT‐WAAM AISI 308L stainless steel. Increasing overlap to 50% promotes stronger bead‐to‐bead bonding, wider transition zones, and localized hardness enhancement, with the highest hardness observed in the overlap region due to grain refinement and δ‐ferrite redistribution.
