Superconductivity in Hierarchical 3D Nanostructured Pb–In Alloys

Symmetry, 2022
The superconducting properties of hierarchical nanostructured samples of Pb–In alloys have been studied by the measurement of dynamic susceptibility χ(T) temperature dependence. Symmetric samples with different shapes and sizes were formed on a brass metallic net by cathode-metal electrodeposition with a programmed pulsing current.

Ultrahigh high-strain-rate superplasticity in a nanostructured high-entropy alloy

Nature Communications, 2020
Superplasticity at high strain rates is challenging to achieve in high strength materials. Here, the authors show superplastic elongation in excess of 2000% in a high entropy alloy nanostructured by high-pressure torsion.
