(Fe,Ni)3(P,B)金属间化合物纳米带是通过所谓的选择性蚀刻方法从前体Fe40Ni40P14B6合金制备的。这些前驱体具有由(Fe,Ni)3(P,B)相和γ-(Fe,Ni)相组成的共晶结构，通过快速淬火方法制备成棒状。然后，通过王水选择性刻蚀，将共晶结构中的γ-(Fe,Ni)相溶解掉，在刻蚀和抛光作用下得到厚度约10-50nm、宽度300-1000nm、长度约10μm或更长的纳米带。根据实验结果，提出了(Fe,Ni)3(P,B)纳米带从共晶结构演化的可能过程。结果表明，选择性刻蚀方法是制备金属纳米带的一种简单有效的方法。
Nano-ribbons of (Fe,Ni)3(P,B) intermetallic compound have been prepared by a so-called selective etching method from the precursor Fe40Ni40P14B6alloys. These precursors, with a eutectic structure constituting of (Fe,Ni)3(P,B) phase and γ-(Fe,Ni) phase, were prepared in a rod shape by the rapid quenching method. Then, the γ-(Fe,Ni) phase was dissolved off from the eutectic structure through selective etching with aqua regia, resulting in nano-ribbons, with about 10–50nm thickness, 300–1000nm width and about 10μm or more length, having been obtained under the action of etching and polishing effects. Based on the experimental results, the possible evolution process of (Fe,Ni)3(P,B) nano-ribbons from eutectic structures was proposed. The present result shows that the selective etching method is an easy and effective approach for preparing metallic nano-ribbons.
