摘要
用单辊快淬法制备Fe_(74)Nb_3Y_3B_(20)非晶合金,在不同温度下对合金进行热处理,利用差热分析仪(DTA,TG/DTA-6300)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)和振动样品磁强计(VSM)等测试方法对合金的微观结构和磁性能进行研究.结果表明,合金经热处理后有α-Fe相和少量的Fe_(23)B_6和Fe_2B析出,热处理后合金饱和磁化强度比淬态的高,矫顽力都比较小,670℃退火的合金具有最高的饱和磁化强度.
Fe74 Nb3Y3B20 amorphous alloy was prepared by melt-spinning technique and annealed at different temperatures. The microstructure and magnetic property were investigated by X-ray diffraction ( XRD), differential thermal analysis ( DTA ), scan electron microscopy ( SEM ) and vibrating sample magnetometer ( VSM ). The results showed that α-Fe, Fe23B6 and Fe2B are precipitated in annealed alloy. The saturation magnetization intensity of annealed alloy is higher and the coercive force is small. The alloy annealed at 670 ℃ has the highest saturation magnetization.
