|Keywords:||Physics - Materials Science;Physics - Materials Science||Issue Date:||Oct-2018||Source:||Scripta Materialia (155): 119-123 (2018-10)||Journal or Series Name:||Scripta Materialia||Abstract (english):||Uniform macroscopic samples of nanoporous metal with high deformability have so far been limited to precious metals such as Au, Pd and Pt. Here we propose nanoporous Copper-Nickel (npCN) as a nanoporous base metal that can be made with mm dimensions and exhibits significant deformability. NpCN forms a uniform bicontinous network structure with feature sizes that can be controlled from 13 to 40 nm by thermal annealing. Continuous compression tests confirm ductile deformation behavior accompanied with a high strength compared to macroporous Cu- and Ni-foams with similar solid fraction.||URI:||http://hdl.handle.net/11420/2499||ISSN:||1359-6462||Institute:||Werkstoffphysik und -technologie M-22||Type:||(wissenschaftlicher) Artikel||Funded by:||Helmholtz-Gemeinschaft HCJRG-315|
