Inhomogeneous dealloying kinetics along grain boundaries during liquid metal dealloying [PDF]

Journal of Materials Science and Technology, 2022
Abstract In this study, the inhomogeneous dealloying phenomenon during the liquid metal dealloying (LMD) was investigated using Fe50Ni50+Mg and (FeCo)50Ni50+Mg systems. For the Fe50Ni50+Mg system, the inhomogeneous dealloying and wetting of Mg melt occurred along triple junction (TJ) and grain boundary (GB).

Effect of dealloying rate on transformation behavior during liquid metal dealloying

Journal of Alloys and Compounds, 2020
Abstract Liquid metal dealloying is a new process that can be applied to synthesize non-noble porous materials by preventing oxidation in a utilized metallic melt. The effect of dealloying rate was investigated by electron backscattered diffraction at the reaction layer at various temperatures (600–800 °C) using (FeCo)xNi100−x precursors in a Mg melt.

Liquid metals dealloying as a general approach for the selective extraction of metals and the fabrication of nanoporous metals: A review

Materials Today Communications, 2021
Abstract Liquid metal dealloying, a method of etching based on different solubilities of each component of the alloy into the liquid metal, has been extensively developed for metallurgical and structural materials applications. This review discusses the development on liquid metal dealloying for recycling alloy scraps and the fabrication of nano ...

Kinetics and morphological evolution of liquid metal dealloying [PDF]

Acta Materialia, 2016
Abstract Liquid metal dealloying (LMD) has recently emerged as a novel technique to fabricate bulk nanostructures using a bottom-up self-organization method, but the literature lacks fundamental studies of this kinetic process. In this work, we conduct an in-depth study of the kinetics and fundamental microstructure evolution mechanisms during LMD ...

From liquid metal dealloying to liquid metal expulsion

Journal of Materials Science, 2020
In liquid metal dealloying, it is assumed that the corrosion product (dealloyed porous solids) is wetted by the liquid metal; otherwise, the dealloying may be halted due to liquid metal expulsion. Here, we report the first observation of liquid metal expulsion in liquid metal dealloying—liquid Ga rushes out of porous C when the dealloying of Mn–C alloy
