Materials and Corrosion, EarlyView.Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

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.

Materialwissenschaft und Werkstofftechnik, EarlyView.The study demonstrated that absorbed energy (Charpy impact test) and fracture toughness (EWF test) are essential for evaluating the mechanical performance of thin sheet metallic materials. Transformation‐induced plasticity (TRIP) steels have been extensively studied concerning their mechanical performance under monotonic loading and conventional ...

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.

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To enable MRI‐based nongated 3D depiction of forced expiration with both high spatio‐temporal resolution and fidelity of lung dynamics. Methods An undersampled 3D Fermat looped, orthogonally encoded trajectory (FLORET) was optimized for nonsegmented dynamic acquisitions during forced expiration and a corresponding model‐based ...
