摘要:
采用双合金法制备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,能获得较好的组织形态;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 ℃烧结时获得较好的磁性能,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.
