为深入了解和应用非晶态合金,研究它们的晶化过程及其热稳定性是十分重要的.本文用DSC-2型示差扫描卡计分别研究了Fe_(40.9)Ni_(39.6)P_(13.1)B_(6.4)和Cu_(58.5)Zr_(41.5)两种非晶态合金在恒速加热条件下的晶化行为及在各自的玻璃转变点附近的等温晶化过程.实验表明:当以10°/分恒速加热时,FeNi基合金的DSC曲线只出现单一的放热峰(如图1);而CuZr合金的DSC曲线却比较复杂(如图2);晶化前发生明显弛豫,玻璃转
In order to understand and apply amorphous alloys, it is very important to study their crystallization process and their thermal stability.In this paper, the differential scanning calorimetry (DSC-2) scanning calorimetry was used to study the effects of Fe 40.9 Ni 39.6 P 13.1 ) Crystallization behavior of two kinds of amorphous alloys B_ (6.4) and Cu_ (58.5) Zr_ (41.5) under isothermal heating conditions and the isothermal crystallization process near their respective glass transition point.The experimental results show that when the content of 10 ° / min constant heating, the DSC curve of FeNi-based alloy showed only a single exothermic peak (Figure 1); while the CuZr alloy DSC curve is more complex (Figure 2); obvious relaxation before crystallization, Glass turn
