摘要

提出了一种基于电沉积的镍铬铁纳米线合成方法。合成的纳米线直径为200 nm,长度超过5 μ m。利用电子显微镜技术对纳米线进行了详细的表征,发现纳米线具有均匀分布的Ni、Fe和Cr原子的非晶结构。利用电子显微镜下的电子束对纳米线进行退火处理,使纳米线的非晶微观结构逐渐结晶为纳米晶微观结构,说明了纳米线微观结构工程的潜力。(C) 2014电化学学会。版权所有。

Synthesis and Electron Microscopy of Superalloy Nanowires
An electrodeposition based methodology for synthesizing Ni-Cr-Fe nanowires is provided. As-synthesized nanowires were 200 nm in diameter and more than 5 mu m in length. Detailed characterization of the nanowires using electron microscopy technique revealed an amorphous microstructure for the nanowires with uniform distribution of Ni, Fe and Cr atoms. Annealing of the nanowire using the electron beam inside electron microscope resulted in gradual crystallization of amorphous microstructure into a nanocrystalline one which illustrated the potential for microstructural engineering of the nanowires.
