| 摘 要： | 为了进一步改善Fe-Nd-Al-B非晶合金的非晶形成能力和磁性能,研究添加Dy元素对此体系合金的显微结构、磁性能以及晶化行为的影响.利用铜模吸铸法制备厚度为1mm的片状(Fe0.51Nd0.35Al0.10b0.40)100-xDyX(x=0,1,3,6)合金.采用示差扫描量热法(DSC),振动样品磁强计(VSM)和X射线衍射仪(XRD)研究Dy对该系列合金非晶形成能力、磁性能和晶化行为的影响.结果表明,添加少量Dy元素使得合金Fe-Nd-Al-B-Dy的磁性能各项指标大幅度提高,得到较好的硬磁性.然而,当进一步提高Dy含量到6%时,合金呈现顺磁性.Fe-Nd-Al-B-Dy系合金晶化后,磁性能会发生很大转变,其中具有较好硬磁性的(Fe0.51Nd0.35Al0.10B0.04)99Dy1合金在完全晶化后呈现为顺磁性.
