The grain texture-oriented Tb0.2Dy0.8−xPrx(Fe0.8Co0.2)1.93 (0 ≤ x ≤ 0.30) 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 -oriented 1–3 type composites for x ≤ 0.10 and -oriented one for x ≥ 0.25 are formed. The 1–3 composite shows the enhanced and reduced magnetostriction effects for x ≥ 0.25 and x ≤ 0.10, respectively, which can be principally ascribed to the formation of -texture-oriented structure in 1–3 composite and the anisotropic nature in magnetostriction coefficients (λ111 and λ100) 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 (d33 ~ 1.8 nm/A at 80 kA/m) and a large low-field longitudinal magnetostriction (λ|| ~ 110 ppm at 80 kA/m), which are in excess of 80% its mother alloy values, even though it only contains 30 vol% alloy particles. These attractive magnetomechanical properties, together with the containing low-cost light rare-earth Pr for 25 at.% with insulating epoxy matrix, could make it technological interest for the field of Pr-containing magnetostrictive materials.
