Microstructural evolution and mechanical behavior of pearlitic steel under multi-directional forging

Journal of Materials Research and Technology
The mechanical behavior and the microstructural evolution of a pearlitic SAE 1080 steel were analyzed along 12 Multi-Directional Forging (MDF) cycles at room temperature and strain amplitude Δε ≈ 0.30 (MDF0.30). The resulting cumulative strain flow curve

Organic anion-intercalation boosting intrinsic Cl− capture capability of layered double hydroxide anode for enhanced capacitive deionization

Green Energy & Environment
Layered double hydroxides (LDH) hold great promise as capacitive deionization (CDI) anodes owing to high Cl− capture capacity and abundant interlamellar ion transport channels.

Effect of the interlamellar spacing on the monotonic and cyclic behavior of C70 pearlitic steel

, 2013
L’effet de l’espacement interlamellaire sur le comportement sous chargements monotone et cyclique de l’acier perlitique C70 a été étudié. Une démarche expérimentale conjuguant les essais de traction « in-situ » sous DRX et traction « in-situ » sous MEB couplées à une modélisation auto-cohérente a été adoptée.
