| 中文摘要 | Pseudo-1-3 magnetostrictive composites of 0.5 volume fraction are fabricated by embedding and aligning stabilizer (B, Co)-free, light rare earth (Pr)-contained magnetostrictive (Tb(0.3)Dy(0.7))(1-x)Pr(x)Fe(1.55) (0 <= x <= 0.4) particles with a size distribution of 10-300 mu m in a passive epoxy matrix. The dynamic magnetomechanical properties of the composites with different Pr content x are investigated as a function of both bias field (=10-200 kA/m) and frequency (=25 Hz-70 kHz). The composites show similar qualitative trends in properties for all x with no frequency dispersion effect except for the resonance range. The dynamic relative permeability mu(T)(r33) demonstrates a decreasing trend with increasing x for the whole range of bias field due to the weakening of saturation magnetization with increasing Pr content. The two elastic moduli E(3)(H) and E(3)(B), which result in negative-Delta E with maximum dynamic strain coefficient d(33) and dynamic magnetome-chanical coupling coefficient k(33) near 140 kA/m bias in all composites, decrease with increasing x for all biases owing to the increasing compliance contribution from Pr. The (Tb(0.3)Dy(0.7))(0.75)Pr(0.25)Fe(1.55) composite exhibits the largest d(33) and k(33) at 140 kA/m bias as a result of the compensation for magnetocrystalline anisotropy. (C) 2008 Elsevier B.V.
