测量非晶合金激活能的新方法

A New Method of Measuring Activation Energy of Amorphous Alloy

介绍了一种测量非晶晶化激活能的新方法——MTGA法。分别用DSC和MTGA研究了Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9非晶合金的晶化动力学。结果表明,MTGA法不但比DSC法能更加详细反映出晶化动力学和相变的过程,而且用DSC和MTGA测量的α—Fe(Si)相的晶化激活能基本一致。

A new method of measuring activation energy of amorphous alloy was introduced. The crystallization kinetics of Fe73.5Cu1 Nb3Si13.5B9 amorphous alloy has been studied by DSC,XRD and MTGA methods. The results show that,for the description of crystallization kinetics and phase transition of amorphous alloy,the MTGA method is more detail than DSC method. The activation energy of amorphous alloy Fe73.5Cu1 Nb3Si13.5B9 measured by MTGA and DSC was coherent.
