Ti元素掺杂对Fe-3Si基软磁复合材料组织结构及磁特性的影响
|
摘要
采用气雾化制粉技术并结合模压成形方法制备xTi/Fe-3Si-0.5Al-2Ni(x=0,1,2)软磁复合材料,通过XRD、SEM、综合物性测量系统(PPMS)以及软磁交流测量仪等装置表征和分析了合金粉末的相结构、形貌、磁特性及Ti/Fe-3Si-0.5Al-2Ni软磁复合材料的磁性能,探讨了Ti元素掺杂对合金粉末居里温度、饱和磁化强度等性能的影响,并着重研究了Ti元素添加对Ti/Fe-3Si-0.5Al-2Ni软磁复合材料有效磁导率、功率损耗、矫顽力等动态磁学特性的影响。结果表明:气雾化合金粉末只存在单一的α-Fe(Si)固溶相,球形度高;Ti元素的掺杂可提高粉末居里温度,但饱和磁化强度有小幅度的弱化;另外,随着Ti元素含量的增加,Ti/Fe-3Si-0.5Al-2Ni软磁复合材料有效磁导率升高,而功率损耗和矫顽力降低,当Ti元素含量为2wt%时,软磁复合材料获得较佳的综合磁性能。
xTi/Fe-3Si-0.5Al-2Ni(x=0,1,2)soft magnetic composites were prepared by gas atomization and compression molding.The phase structures,morphologies and magnetic properties of the both powders and Ti/Fe-3Si-0.5Al-2Ni soft magnetic composites were analyzed by XRD,SEM,physical property measurement system(PPMS)and soft magnetic alternating current measuring instrument.The effects of Ti element doping on curie temperature and saturation magnetization of alloy powders as well as permeability,loss,coercivity of Ti/Fe-3Si-0.5Al-2Ni soft magnetic composites were investigated.The results indicate that the gas-atomized powders have high sphericity and only singleα-Fe(Si)solid solution phase.Ti element doping can increase the curie temperature of the Ti/Fe-3Si-0.5Al-2Ni powders,but lower the saturation magnetization,however,the loss,coercivity and the effective magnetic permeability of Ti/Fe-3Si-0.5Al-2 Ni soft magnetic composites are improved by increasing Ti mass fraction up to 2 wt%,at which the comprehensive magnetic properties are optimized.
