摘要:
采用双合金法制备了Nd24.38Ce0.52Gd6.65Febal.TM1.76B0.95(质量分数,%)永磁体,通过扫描电镜及能谱、AMT-4磁测试仪、电子万能力学试验机等手段研究了烧结温度对磁体组织和性能的影响。结果表明:随烧结温度从1 060 ℃升高到1 100 ℃,在烧结温度为1 080 ℃时,晶粒均匀且结合致密,富稀土相分布均匀,获得了最佳的组织形态;富稀土相中稀土总含量从84.98%增加到98.04%,烧结过程中铈从主相显著扩散到富稀土相;磁体剩磁Br、矫顽力Hcj、磁能积(BH)max先升后降,在1 080 ℃烧结时获得了最佳磁性能,分别为1.22 T、964 kA/m和293 kJ/m3,同时磁体抗弯强度也达到最大值为257 MPa。
