, PP. 65-69
Keywords: 非晶合金,晶化激活能,局域Avrami指数,(Fe_(0.99)Cu_(0.01))_(78)Si_9B_(13)合金
Abstract:
利用DSC,结合XRD,TEM实验,研究了(Fe_(0.99)Cu_(0.01))_(78)Si_9B_(13)非晶合金等温晶化动力学,结果表明该合金等温晶化按两个阶段进行,分別析出α-Fe(Si)固溶体和Fe_2B化合物利用局域Avrami指数的概念分析了两相的形核长大方式。并作出了出合金晶化的“C”曲线,通过对两相晶化激活能的分析得出α-Fe(Si)相较Fe_2B相容易晶化析出,同时,Cu元素的添加有助于改善α-Fe(Si)相的形貌。
