Abstract

We have succeeded to form three-dimensionally orientated nano-sized crystals in a Ni-P amorphous alloy under focused ion beam (FIB) irradiation. The FIB micro-fabrication was performed on an electroless deposited Ni-P amorphous alloy and thin films with a thickness of 100 nm were prepared. Transmission electron microscopy (TEM) observation for irradiated areas revealed the formation of crystallographically orientated nano-sized crystals (NCs) in the irradiated region. The grain size of NCs was less than 10 nm in diameter. Electron diffraction analysis showed that the formed NCs have a face-centered-cubic (f.c.c.) structure and the following orientation relationships among the specimen, the NCs and the FIB direction: irradiated plane // {111}f.c.c. and ion beam direction // <110>f.c.c..
