In-situ multi-scale deformation behaviors of Portevin-Le Chatelier bands in Al-Mg-Sc-Zr alloys

Materials Research Letters
This study investigates the multi-scale deformation behaviors of Portevin–Le Chatelier (PLC) bands in an Al-Mg-Sc-Zr alloy using in-situ scanning electron microscopy (SEM) tensile testing combined with multi-scale digital image correlation (DIC).

In-situ tensile study of Fe and trace B effects on deformation behavior and strengthening mechanisms in LDED-fabricated Ti-6Al-4V alloys

Materials & Design
The Ti-6Al-4V (Ti64) alloy, modified with Fe and B via laser-directed energy deposition (LDED), exhibits significant microstructural refinement and an enhanced synergy between strength and ductility.

Pinning-dominated strengthening in high-entropy superalloys

Hierarchical microstructural design of high-entropy superalloys offers novel strengthening pathways beyond classical superalloys. Here we assess the strength of isolated γ’ precipitates with and without an additional internal γ nanophase.
