摘要The grain texture-oriented Tb0.2Dy0.8-xPrx(Fe0.8Co0.2)(1.93) (0x0.30) pseudo 1-3 particulate composites are fabricated by integrating alloy particles embedded in an epoxy matrix with the presence of a magnetic field. The structural and quasi-static magnetomechanical properties are investigated in comparison with their monolithic alloys and 0-3 type particulate composites. The < 100 >-oriented 1-3 type composites for x0.10 and < 110 >-oriented one for x0.25 are formed. The 1-3 composite shows the enhanced and reduced magnetostriction effects for x0.25 and x0.10, respectively, which can be principally ascribed to the formation of < uvw >-texture-oriented structure in 1-3 composite and the anisotropic nature in magnetostriction coefficients ((111) and (100)) of the embedded alloy particles. The 1-3 type Tb0.2Dy0.55Pr0.25(Fe0.8Co0.2)(1.93) composite demonstrates the enhanced magnetomechanical properties, i.e., a high piezomagnetic coefficient (d(33)similar to 1.8nm/A at 80kA/m) and a large low-field longitudinal magnetostriction ((||)similar to 110ppm at 80kA/m), which are in excess of 80% its mother alloy values, even though it only contains 30vol% alloy particles. These attractive magnetomechanical properties, together with the containing low-cost light rare-earth Pr for 25at.% with insulating epoxy matrix, could make it technological interest for the field of Pr-containing magnetostrictive materials.
