Self-assembled porous metal-intermetallic nanocomposites via liquid metal dealloying

Acta Materialia, 2019
Abstract A major challenge in the synthesis of high surface area metals via subtractive processes such as dealloying is maintaining the mechanical integrity of the resulting porous materials. This problem is especially apparent in liquid metal dealloying, in which high-temperature selective dissolution in a molten metal bath leads to bicontinuous ...

Three-Dimensional Morphological and Chemical Evolution of Nanoporous Stainless Steel by Liquid Metal Dealloying

ACS Applied Materials & Interfaces, 2017
Nanoporous materials, especially those fabricated by liquid metal dealloying processes, possess great potential in a wide range of applications due to their high surface area, bicontinuous structure with both open pores for transport and solid phase for conductivity or support, and low material cost.

Preparation of bulk Cu-W interpenetrating-phase composites by liquid metal dealloying

International Journal of Refractory Metals and Hard Materials, 2021
Abstract Copper-Tungsten (Cu-W) composites are promising materials for electrical and thermal applications. Manufacturing the desired Cu-W composites with full densification and a homogenous microstructure remains difficult, however, owing to the lack of mutual solubility, poor wettability, and the large difference in melting temperature between W ...

Preparation of hierarchical porous metals by two-step liquid metal dealloying

Scripta Materialia, 2018
Abstract A hierarchical porous metal has been prepared by two-step liquid metal dealloying using an alloy precursor containing two soluble components and two metal baths. After the first dealloying step, one of the soluble components is dissolved and a coarse porous structure is formed.

Ordering kinetics of nanoporous FeCo during liquid metal dealloying and the development of nanofacets

Scripta Materialia, 2020
Abstract Three-dimensional interconnected nanoporous FeCo can be prepared by liquid metal dealloying. This study investigates the surface morphology and ordering kinetics of three-dimensional interconnected nanoporous FeCo. The chemical composition and dealloying temperature mutually influence the surface structure of the ligament scaffold.

Local heterogeneity in the mechanical properties of bicontinuous composites made by liquid metal dealloying

Applied Physics Letters, 2016
Bicontinuous composites made by liquid metal dealloying are excellent structural materials, with a unique combination of size-dependent strengthening and facile fabrication. However, due to the stochastic nature of dealloying, the local composition of individual ligaments can vary significantly and it is an open research question how this affects the ...
