Alloy composition dependence of formation of porous Ni prepared by rapid solidification and chemical dealloying

Electrochemical fabrication of a porous nanostructured nickel hydroxide film electrode with superior pseudocapacitive performance

“…3b. The obtained nanohollow tube structure is significantly different from the interconnected bicontinuous nanopores that are usually achieved by dealloying from a homogeneous binary solid solution alloy [27,28]. Fig.…”

Bulk Nanoporous Metal for Actuation

“…In spite of these concerns, the formation of monolithic nanoporous metal has been reported even when the master phase is an intermetallic, as in Al-Ni and Al-Cu. [18,19] Defect structure and orientation relationships at the corrosion front remain to be studied for such processes.…”

Influence of rotating magnetic field on the microstructure and phase content of Ni–Al alloy

“…As well known, many defects and sometimes metastable phase exist in the alloys prepared by mechanical alloying and rapid solidification. And those defects play a very important role in accelerating the following dealloying process [12]. Moreover, metastable phases [5] have different leaching resistance and leave specific structure compared with Al 3 Ni and Al 3 Ni 2 .…”

“…Different phases have various strengths and leaching resistance and lead to different catalytic activities [1,3]. Therefore, many alloy production technologies which can change the alloy structure, such as mechanical alloying [4][5][6][7][8], rapid solidification [9][10][11][12][13][14][15][16] and adding alloying element combined with previous procedure are used to produce precursor alloys. Better skeletal catalysts are obtained, but many factors which affect the catalytic performance are mixed together.…”
