Iron and steel corrosion mechanisms in a carbonate rich pore water: Multiscale characterization of the corrosion product layers

Materials and Corrosion, Volume 74, Issue 1, Page 8-19, January 2023., 2023
Corrosion experiments were performed on a ferrito‐pearlitic and a ferritic steel in a synthetic solution representing the Callovo‐Oxfordian porewater during a month at 120°C. Corrosion product layers (CPLs) were characterized from micro to nanoscale in terms of morphology, composition, and structure.

Time‐Resolved Dynamics of Laser Ablation in Liquid with Gas‐Evolving Additives: Toward Molding the Atomic Structure of Nonequilibrium Nanoalloys

Advanced Science, EarlyView.
Laser ablation in liquid still holds great potential for the synthesis of multicomponent non‐equilibrium nanomaterials. Here, time‐resolved experiments reveal that gas‐evolving additives both have chemical effects and reduce shockwave pressure. This approach offers a strategy to control the atomic structure of the nanoalloys, easily switching from ...

Defect Engineering in Wüstite: Unlocking Control Over Iron Morphologies in Gas‐Solid Reduction

Advanced Science, EarlyView.
In this paper, a direct link between the concentration of defects in wüstite (FexO) and the resultant iron microstructure is established. By integrating the muti‐point nucleation and morphological evolution of iron at defect sites, a multiscale perspective on how defect engineering in FexO modulates the morphologies of iron has been developed ...
