用差热分析（ＤＴＡ） ，结合Ｘ 射线衍射（ＸＲＤ） 研究了Ｓｍ８Ｆｅ８５Ｓｉ２Ｃ５ 非晶合金的晶化动力学。试验结果表明：在０ ～９００ ℃，该合金晶化相和Ｓｍ２（ＦｅＳｉ）１７ＣＸ 在晶化初期激活能变化不大，当晶化量ＸＣ（αＦｅ） 大于７０ ％ 、ＸＣ［Ｓｍ２（ＦｅＳｉ）１７Ｃｘ］ 大于５０ ％ 时，两相晶化激活能开始减小。
The crystallization kinetics of Sm8Fe85Si2C5 amorphous alloy was investigated by DTA and XRD. The experimental results show that the activation energy of the alloy and Sm2 (FeSi) 17CX does not change much at the initial stage of crystallization at 0-900 ℃. When the amount of XC (α-Fe) is more than 70%, the activation energy of XC [Sm2 ) 17Cx] is greater than 50%, the two-phase crystallization activation energy begins to decrease.
