| 摘 要： | 研究了非晶Ｆｅ（８０）Ｂ（２０）合金的表观晶化动力学过程，分析表明，非晶态的Ｆｅ－Ｂ共晶合金在晶化过程中，晶体的生长行为与传统观点所认为的完全由界面控制的机制不同，还同时存在扩散控制机制．

| Abstract: | By use of a differential scanning calorimeter, the crystallization kinetics of an amorphous Fe80B20 alloy was studied. The kinetic parameters of crystallization, such as the transformed fraction x(t),the local activation energy Ec(x), and the average Avrami exponent n, were analyzed. The crystal growth in this alloy is not only interface-controlled but also diffusion-controlled. |
