摘　　要：利用熔体急冷法制备Fe(Co)-Hf-B-Cu铁基条带非晶合金。采用XRD、穆斯堡尔谱和透射电镜确定非晶态结构,利用差热扫描量热法对不同样品的热稳定性进行测试分析。结果表明,冷速大的样品热稳定性好,添加纯B比添加FeB的样品热稳定性好,添加适量的Co可以提高非晶合金的热稳定性,所制备的各个样品均展现出非晶态结构特征。The thin strips of Fe(Co)-Hf-B-Cu iron-based strip amorphous alloys were prepared by single-roller-quenching method. The amorphous structure was determined by XRD, M.ssbauer spectroscopy and transmission electron microscopy. The thermal stability of different samples was tested by differential scanning calorimetry. The results indicate the glassy structure of all the samples. Furthermore the results indicate that the thermal stability of amorphous alloys can be increased by faster cooling rate or adding pure B elements. And it can be also identified to improve the thermal stability of amorphous alloys that alloying components with the appropriate amount of Co.
