With an eye on the role of structure size and topology, this study explores the mechanical behavior of nanoporous (NP) Nb made by liquid-metal dealloying. Results from X-ray nanotomography and macro-compression tests confirm that coarsening degrades

In this study, the consequence of intrinsic and extrinsic size effects on mechanical responses of nanoporous gold is investigated via microcompression testing. By varying the micropillar diameter (D) between 1 µm and 20 µm and the ligament size (L)

The datasets in this work are files containing atom position coordinates of volume elements approximating nanoporous gold made by dealloying and annealing. The material is represented in an as-prepared state and in various stages of coarsening, as de

Nanoscale crystals can experience lattice instability and a tension-compression asymmetry of their strength. Here, Mameka and colleagues scrutinize the proposition that these phenomena arise from surface-induced stress, finding that the surface tensi

A two-stage lightweighting Dealloying allows voids to be created in metals, decreasing the weight of the material. However, when the solid fraction is below about 30%, the mechanical properties rapidly degrade. Shi et al. discovered that two dealloyi

This work presents systematic investigations on the synthesis of hierarchical nanoporous Pd via electrochemical dealloying of CuPd alloys in sulfuric acid. The impact of electrode potential, dealloying temperature, and additional annealing on microst

Here, we developed open porous TiFe and TiNb alloys by liquid metal dealloying. Tuning dealloying parameters allows controlling phase formation and microstructure of the resulting structures. Particularly, α″ martensite together with β-Ti and sin
