    摘要:

    在差热扫描分析仪上以不同加热速率测试非晶 Fe78Si11B9 和纳米晶 Fe73.5Cu1B7Si15.5Nb3 合金晶化情况,采用Kissinger方程计算非晶Fe78Si11B9合金的激活能为(370±3) kJ,Fe73.5Cu1B7Si15.5Nb3纳米晶第一晶化相的激活能为(295±5) kJ;提出纳米晶Fe73.5Cu1B7Si15.5Nb3合金初晶

    Abstract:

    The activation energies of amorphous Fe78Si11B9 and nanocrystalline Fe73.5Cu1B7Si15.5Nb3 alloys were tested by a high-sensitivity differential scanning calorimeter with different heating rates. Kissinger equation was adopted to calculate the activation en
