采用单辊快淬法制备Fe40 Co40 Zr7 V2 B9 Ta2非晶合金薄带,并对该合金在不同温度下进行热处理。利用差热分析(DTA)、X 射线衍射(XRD)、扫描电镜(SEM)和振动样品磁强计(VSM)测量合金的热性能、微观结构及磁性能。结果表明：Fe40 Co40 Zr7 V2 B9 Ta2合金的初始晶化产物为α-FeCo相,高温时析出ZrCo3 B2,Co23 Zr6和ZrB2相；薄带横断面的形貌在快淬态和300℃退火后,合金的自由面呈网状结构,贴辊面呈枝状结构；高于550℃退火,横断面呈颗粒状；550℃退火后合金的矫顽力(H c )最小,高于550℃退火,H c 随退火温度的升高而增大。

Amorphous Fe40 Co40 Zr7 V2 B9 Ta2 ribbons were prepared by single roller melt-spinning and annealed at different temperatures.The thermal property,microstructure and magnetic property of the samples were investigated by differential thermal analysis (DTA),X-ray diffraction (XRD), scanning electron microscopy (SEM)and vibrating sample magnetometric (VSM)analysis.The initial crystallization product of Fe40 Co40 Zr7 V2 B9 Ta2 was anα-FeCo phase.ZrCo3 B2 ,Co23 Zr6 and ZrB2 phases were then precipitated at high temperatures.From the appearance of the cross section,the free area showed a mesh structure and the contact area showed a dendritic structure in the Fe40 Co40 Zr7 V2 B9 Ta2 alloy when it was quenched and annealed at 300 ℃.When the alloy was annealed at above 550 ℃,the cross section showed the granular structure.H c of Fe40 Co40 Zr7 V2 B9 Ta 2 alloy annealed at 550 ℃ is minimum.H c increased with the increase of annealing temperature above 550 ℃.
