The magnetic and magnetostrictive properties of epoxy bonded Tb1–xPrx(Fe0.4Co0.6)1.93 (0.85≤x≤1.00) composites, prepared with different epoxy proportions using cold compression-molding technique, were investigated. It is found that the optimal conditions were with a compaction pressure of 100 MPa and a mass ratio of resin to powder of 5:100. The Tb0.1Pr0.9(Fe0.4Co0.6)1.93 composite rod had a high magnetostriction of 770 ppm at an applied magnetic field of 960 kA/m, whereas the Pr(Fe0.4Co0.6)1.93 composite reached 500 ppm at 400 kA/m. The good magnetostrictive properties of Pr(Fe0.4Co0.6)1.93 composite at low-field (≤400 kA/m) could be explained by its low anisotropy. These results indicated that the epoxy bonded Tb1–xPrx(Fe0.4Co0.6)1.93 rod samples for high Pr content of x=0.9–1.0 were of practical value.
