用差热分析（DTA），结合X射线衍射（XRD）研究了Sm8Fe83Si2C5Cu0.5Nb1.5非晶合金的晶化动力学．结果表明：温度在0～1000℃范围内，该合金的晶化相为α-Fe和Sm2（FeSi）17Cx.α-Fe相的晶化表观激活能为349．53kJ／mol，Sm2（FeSi）17Cx的晶化表观激活能为316．19kJ／mol，两相在晶化初期激活能最小，随晶化量（Xc）的增加激活能增大，当α-Fe相的体积分数为20-50％，Sm2（FeSi）17Cx的体积分数为6-50％时，两相晶化激活能呈极大值。
The crystallization kinetics of Sm8Fe83Si2C5Cu0.5Nb1.5 amorphous alloy was studied by differential thermal analysis (DTA) and X-ray diffraction (XRD). The results show that the crystallization temperature of the alloy is α-Fe and Sm2 (FeSi) 17Cx in the temperature range of 0 ~ 1000 ℃. The crystallization activation energy of α-Fe phase is 349.53kJ / mol, Sm2 (FeSi ) 17Cx has an apparent activation energy of 316.19 kJ / mol. The activation energy of the two phases in the initial stage of crystallization is the smallest, and the activation energy increases with the increase of the amount of crystallization (Xc). When the volume fraction of α-Fe phase is 20 -50%, and the volume fraction of Sm2 (FeSi) 17Cx is 6-50%, the activation energy of the two phases has the maximum value.
