| 摘 要： | 采用单辊法和铜模铸造法制备了Fe75-xMxHf3Y2B20(M=Co,Nb;x=0,4 at%)合金系的非晶薄带和非晶棒样品,并测试了该非晶合金系的差示扫描量热曲线、X射线衍射图谱和软磁性能.结果表明:少量的Nb或Co替代Fe75Hf3Y2B20中的Fe元素,合金的热稳定性和玻璃形成能力可得到明显的提高;其中Fe71Nb4Hf3Y2820的过冷液相区宽度△Tx高达75 K,约化玻璃转变温度Trg为0.58,直径达4 mm,饱和磁感应强度为0.97～1.08 T,该非晶合金同时具有较大的热稳定性、较强的玻璃形成能力和较好的软磁性能.

| Abstract: | Amorphous ribbon and rods of Fe75-xMxHf3Y2B20(M=Co, Nb; x=0, 4) alloys were prepared by the melt-spun and copper mold casting method, respectively. The thermal stability, crystallization, melting behavior and soft magnetic properties were investigated by differential scanning calorimetry (DSC), differential thermal analysis (DTA), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The results indicate that the thermal stability and glass-forming ability of Fe75Hf3Y2B20 can be obviously increas... |
