摘要	Pseudo-1-3 magnetostrictive composites consisting of stabilizer ( B, Co)-free, light rare earth (Pr)-containing magnetostrictive (Tb0.3Dy0.7)(1-x) Pr-x Fe-1.55 (0 <= x <= 0.4) particles with a size distribution of 10-300 mu m embedded and aligned in a passive epoxy matrix using 0.5 volume fraction are fabricated. The quasistatic magnetomechanical properties of the composites are investigated and compared with their monolithic (Tb0.3Dy0.7)(1-x) Pr-x Fe-1.55 alloys, as a function of the Pr content x. The composites show similar qualitative trends in properties with the alloys for all x. The (Tb0.3Dy0.7)(0.75)Pr0.25Fe1.55 composite and alloy exhibit the smallest coercivity H-c, the largest magnetostriction lambda and the highest piezomagnetic coefficient d(33) due to the successful compensation for magnetocrystalline anisotropy. The ( Tb0.3Dy0.7) 0.75Pr0.25Fe1.55 composite demonstrates a large saturation magnetostriction lambda(s) of 793 ppm at 700 kAm(-1) and a high d(33) of 3.2 nmA(-1) at 140 kAm(-1). These values approach 81% and 85% of its alloy values at the same field levels. The good properties make the (Tb0.3Dy0.7)(0.75)Pr0.25Fe1.55 composite and alloy a promising magnetostrictive material system.
