(Tb0.36Dy0.64)(1-x)HoxFe1.95 magnetostrictive alloys with < 110 > orientation were prepared by zone melting directionally solidified method. The magnetostrictive performance and hysteresis of < 110 > aligned polycrystalline (Tb0.36Dy0.64)(1-x)HoxFe1.95 were investigated under applied magnetic field H (0 < H < 4 kOe) in the temperature range from -60 to 80 degrees C with 0, 5 and 10 MPa pre-stress. The (Tb0.36Dy0.64)(1-x) HoxFe1.95 alloys (x < 0.3) have the character of giant magnetostriction from -60 to 80 degrees C. An obvious magnetostrictive "jump" effect was observed in these samples from -60 to 80 degrees C. The pre-stress and temperature dependence of the W-h was also examined. Between the temperature range from -60 to 80 degrees C, the magnetostriction increased with temperature decreased, while the magnetostriction hysteresis decreased, with the pre-stress increased, but the magnetostriction and the magnetostrictive hysteresis increased.
