FeB金属玻璃由于具有高饱和磁化强度、低损耗,可望作为变压器材料而受到重视,并进行广泛研究.但国产FeB_(20)金属玻璃尚很少研究,热稳定性和晶化动力学数据缺乏.热稳定性是非晶材料形成和使用的重要性质.我们用CDR-1型差动热分析仪(DSC)测定上海有色所双辊急冷方法制备非态FeB_(20)合金条带,在恒速升温过程和等温退火过程中,样品由非晶态到晶态的转变.
Due to its high saturation magnetization and low loss, FeB metallic glass is expected to be valued as a transformer material and extensive research has been carried out.But FeB 20 metallic glass is rarely studied, and its thermal stability and crystallization kinetics data are lacking Thermal stability is an important property for the formation and use of amorphous materials.We measured the non-state FeB_ (20) alloy ribbon by double-roll quenching method of Shanghai Nonferrous Metals Co., Ltd. by using the DSC-1 differential thermal analyzer (DSC) During the heating process and isothermal annealing process, the sample changes from amorphous to crystalline.
