摘 要：(Tb0.36Dy0.64)1-xHoxFe1.95 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-xHoxFe1.95 were investigated under applied magnetic field H（0<H<4 kOe） in the temperature range from-60 to 80 oC 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 oC.An obvious magnetostrictive "jump" effect was observed in these samples from-60 to 80 oC.The pre-stress and temperature dependence of the Wh was also examined.Between the temperature range from-60 to 80 oC,the magnetostriction increased with temperature decreased,while the magnetostriction hysteresis decreased,with the pre-stress increased,but the magnetostriction and the magnetostrictive hysteresis increased.
