%X 用X射线衍射、吸收和内转换电子发射Mossbauer谱技术,研究了Fe_(80-x)Cu_xSi_5B_(15)和(Fe_(1-y)Co_y)_(82)Cu_(0.4)Si_(4.4)B_(13.2)两系列非晶合金的晶化行为.单辊急冷法制备的非晶带,晶化首先从贴辊面开始,晶化产物为α-Fe相.在Fe_(80)Si_5B_(15)非晶合金中以少量Cu替代Fe可以提高晶化温度.我们的结果表明,过渡金属的含量超过80at.-%,如增加到82at.-%,晶化温度就明显降低.所研究两系列含Si的铁基非晶合金在400—450℃范围内退火2h,都出现α-Fe,Fe_3B和Fe_2B三种晶态相共存状态.退火温度再升高,亚稳相Fe_3B逐渐转变为Fe_2B和α-Fe.
