用透射电镜研究了Ni-P非晶态合金在聚焦离子束辐照下的结构变化。在辐照平面上，观察到晶体学取向的纳米晶体（NC）的形成，具有约10 nm的颗粒尺寸。一系列电子衍射分析表明，纳米碳具有面心立方（fcc）结构，纳米碳与FIB方向的取向关系为：辐照面//（111）fcc和FIB方向/（110）fcc。
Structural changes of a Ni–P amorphous alloy under focused-ion-beam (FIB) irradiation have been examined using transmission electron microscopy. On the irradiated plane, the formation of crystallographically orientated nanosized crystals (NCs), with the particle size of approximately 10 nm, was observed. A series of electron diffraction analyses have revealed that NCs have a face-centered-cubic (fcc) structure and the following orientation relationships between the NCs and the FIB direction were found. These are, irradiated plane//(111)fcc and FIB direction//〈110〉fcc.
