【摘要】 用液态金属单辊熔融急冷法制成了Fe_73.5CuNb₃Si_13.5B₉和Fe_69.5CuNb₃Co₄Si_13.5B₉ 非晶合金条带,用DSC、MTGA 法和X 射线衍射研究Co 对Fe_73.5Cu₁Nb₃Si_13.5B₉ 非晶合金的非晶纳米晶化的影响数据表明,加Co 后的合金具有一些优良的热磁性质。介绍了一种测量非晶晶化激活能的新方法—MTGA法。更多还原

【Abstract】 The Effect of Co on the Crystallization Kinetics of Fe_73.5Cu₁Nb₃Si_13.5B₉ amorphous alloy has been studied byDSC,XRD and MTGA methods A new method of measuring activation energy of amorphous alloy was introduced..The results show that, for the description of crystallization kinetics and phase transition of amorphous alloy, the MTGAmethod is more detail than DSC method. The activation energy of amorphous alloy Fe_73.5Cu₁Nb₃Si_13.5B₉ measured byMTGA and DSC was coherent.更多还原
