采用环氧树脂粘结Sm0.88Nd0.12Fe1.93合金颗粒,在外磁场中固化成型制备了磁致伸缩复合材料,研究了不同磁场中成型复合材料的显微组织、磁致伸缩和电阻率.结果表明,成型磁场为0T时,复合体系为0-3型构型,合金颗粒在树脂基体中无序分布;施加0.6 T的固化磁场,获得伪1-3型构型复合材料,合金颗粒趋近定向排列.Sm0.88Nd0.12Fe1.93合金颗粒体积分数为30％、固化磁场为0.6 T时,制备的复合材料在1.3 T磁场下的磁致伸缩系数(λ∥-λ⊥)可达-1088×10-6,为铸态合金磁致伸缩系数的86.6％.相同颗粒体积分数的粘结Sm0.88Nd0.12Fe1.93复合材料,固化磁场为0.6T较无固化磁场条件下的电阻率降低85％.
