采用铜模真空吸铸法、X射线衍射仪(XRD)、示差扫描量热分析仪(DSC)及振动样品磁强计(VSM),研究稀土元素Y及Fe/Co比例变化对FeCoBSiNb(Y)系合金的玻璃形成能力、热稳定性及磁性能影响.实验结果表明,添加4%(原子分数)的Y有利于(Fe0.5 Co0.5)72B19.2 Si4.8Nb4合金玻璃形成能力的提高;随着Fe/Co比例的增加,(FexCo1-x)72B19.2Si4.8Nb4和[(Fe1-xCox)0.72B0.192Si0.048Nb0.04]96Y4合金系的过冷液相区(△Tx)减小,玻璃形成能力下降,但饱和磁化强度均逐渐增大;添加稀土元素Y后,[(Fe1-xCOx)0.72B0.192Si0.048Nb0.04]96Y4非晶合金的饱和磁化强度均有一定程度的下降.
