用化学还原法制备了Ni－B、Co－B及不同含量的Ni－Co－B超细非晶态微粒．电感耦合等离子光谱（ICP）测定合金的组成表明：微粒中Ni与Co的含量可通过调节反应溶液中Ni与Co离子浓度来控制．X衍射（XRD）、透射电镜（TEM）及电子衍射证实合金是粒径约为20nm的非晶相球状颗粒．用示差量热法（DSC）考察了制备条件对非晶态合金热稳定性的影响．发现相同组成不同含量及不同条件下制得的样品其热稳定性均有差异．初步解释了引起这种差别的原因．从而揭示了非晶态合金结构的复杂性．
Ni-B, Co-B and different contents of Ni-Co-B ultrafine amorphous particles were prepared by chemical reduction method. The composition of the alloy determined by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP) shows that the content of Ni and Co in the particles can be controlled by adjusting the concentration of Ni and Co in the reaction solution. X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron diffraction confirmed that the alloy is a spherical amorphous particle about 20nm in size. The effect of preparation conditions on the thermal stability of amorphous alloys was investigated by differential scanning calorimetry (DSC). The samples with the same composition and content under different conditions were found to have different thermal stability. The initial explanation for the reasons for this difference. Thus revealing the complexity of the amorphous alloy structure.
