摘要：

A novel lamellar NiAl nanochannel with NiAl lamellae and nanochannels was fabricated from directionally solidified NiAl-Cr(Mo) eutectic alloy by selective phase dissolution. The optimum potential for the selective dissolution was at 1.14 V-SHE. Results revealed that the Cr(Mo) phase in the NiAl-Cr(Mo) eutectic was removed completely, and the lamellar nanochannel was revealed during the selective dissolution. The width of the nanochannel was 620 nm, and the depth approached 83.6 mu m; both can be tuned by controlling the growth rate and dissolution time. These highly oriented NiAl architectures with narrow nanochannels can be used to fabricate multilayered devices/capacitors.
