Effect of Copper and Niobium Addition on Crystallization Kinetics in Fe-Cu-Nb-Si-B Alloys

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
