英文摘要	X-ray diffraction (XRD) and differential scanning calorimetry (DSC) were employed to investigate the effect of cooling rate on both non-isothermal and isothermal crystallization behavior of metallic Co43Fe 20Ta5.5B31.5 glass. It is found that all DSC traces of the metallic Co43Fe20Ta5.5B 31.5 glasses under different cooling rates exhibit one exothermic peak, which indicates that the crystallization of metallic Co 43Fe20Ta5.5B31.5 glass follows a one-stage process. The XRD patterns of the metallic Co43Fe 20Ta5.5B31.5 glasses under different cooling rates after non-isothermal DSC up to 1150 K show that all melt-spun ribbons of Co43Fe20Ta5.5B31.5 alloys produced under different cooling rates have the same precipitation phases after crystallization in the continuous heating DSC. In the case of non-isothermal crystallization process, the thermodynamic parameters are not affected by the cooling rate. During the isothermal annealing, the cooling rate also does not change the crystallization kinetics of metallic Co43Fe 20Ta5.5B31.5 glass, but the nucleation rate in the whole crystallization process. The magnetic hysteresis loops measuring indicates that the values of saturation moment and coercivity exhibit correlation with the cooling rate. © 2006 Springer Science + Business Media, Inc.
