Abstract

The aim of the present work was to investigate an influence of W addition on the phase constitution, microstructure and magnetic properties of the PrFeWB (where: x = 2, 4, 6, 8) alloy ribbons. Ribbons were obtained using the melt-spinning technique under low pressure of Ar. The as-cast samples were fully amorphous and revealed soft magnetic properties. These facts were confirmed by X-ray diffractometry, Mössbauer spectroscopy and magnetic measurements. Differential scanning calorimetry and differential thermal analysis allowed us to determine the thermal stability parameters of the amorphous phase. The Kissinger plots were constructed in order to calculate the activation energies for crystallization. Heat treatment carried out at various temperatures caused changes in the phase constitution and magnetic properties of the alloys. The phase analysis has shown the presence of the hard magnetic PrFeB and paramagnetic PrFeB phases. Additionally, for the x = 2 and x = 6 alloys, a crystallization of soft magnetic FeB and α-Fe phases was observed. The Mössbauer spectroscopy allowed us to determine the volume fractions of constituent phases formed during annealing. The microstructure of annealed ribbons was observed using transmission electron microscopy.

摘要

本工作的目的是研究添加W对PrFeWB（其中：x = 2、4、6、8）合金薄带的相组成、微观结构和磁性能的影响。薄带是在低氩压下采用熔体纺丝技术制备的。铸态样品完全非晶态，并表现出软磁性能。这些事实通过X射线衍射、穆斯堡尔光谱和磁测量得到了证实。差示扫描量热法和差热分析使我们能够确定非晶相的热稳定性参数。构建基辛格曲线以计算结晶活化能。在不同温度下进行的热处理导致了合金相组成和磁性能的变化。相分析表明存在硬磁PrFeB相和顺磁PrFeB相。此外，对于x = 2和x = 6的合金，观察到软磁FeB相和α-Fe相的结晶。穆斯堡尔光谱使我们能够确定退火过程中形成的组成相的体积分数。使用透射电子显微镜观察了退火薄带的微观结构。
