Tunable electromagnetic properties via dealloying in FeCoNiCuAl high-entropy alloys for efficient electromagnetic-wave absorption

Applied Physics Letters
High-entropy alloys (HEAs), especially the FeCoNi-based HEAs with magnetic loss and dielectric loss, have attracted considerable attention in the field of electromagnetic-wave absorption (EMA).

Dealloying by metallic melt

Materials Letters, 2011
Abstract Dealloying, which commonly involves corrosion processes in aqueous solutions, is a promising technique for preparing functional nanoporous metals. While this technique is ideal for preparing nanoporous noble metals such as of Au, it is not readily applicable to less-noble metals.

Microstructure and phase evolution during the dealloying of bi-phase Al–Ag alloy

Corrosion Science, 2013
The chemical dealloying of bi-phase Al-35Ag alloy has been investigated within the parting limit. The dealloying of α-Al(Ag) and AgAl commenced simultaneously, and all α-Al(Ag) and part of AgAl were dealloyed, leaving residual AgAl to be dealloyed ...

Shape regulation of high-index facet nanoparticles by dealloying

Science, 2019
Stabilizing rougher nanoparticles For many reactions catalyzed by metal nanoparticles, the more exposed metal atoms on high-index faces can be more active than metal atoms on smooth, low-index faces.

Nanocatalysts Fabricated by a Dealloying Method

The Chemical Record, 2015
AbstractTwo types of nanomaterials with different morphologies are described in this article: nanoporous metals and titanate nanowires. Both materials are fabricated by a dealloying method. In the former case, the catalytic properties of nanoporous gold and palladium are exemplified by many chemical transformations.

Electrochemical Dealloying with Simultaneous Phase Separation

SSRN Electronic Journal, 2018
Dealloying is a selective corrosion process during which the more electrochemically active elements in a parent alloy dissolve while the remaining more noble atoms diffuse along the solid-electrolyte interface, resulting in the formation of a nanoporous microstructure composed of core-shell ligaments.
