Hysteresis property of stress-strain relation for Tb0.3Dy0.7Fe2 <110> oriented polycrystal

摘要：

The Tb0.3Dy0.7Fe2 <110> oriented alloy was grown by zone melting directional solidification technique. The strain-stress loops of the alloy in different magnetic fields have been measured, and the effect of stress and magnetic field on strain difference △ε has been confirmed. It is found that the strain difference △ε quickly increases with increasing the stress when the stress is less than 10 MPa and decreases in the range of 10-40 MPa when the magnetic field is in the range of 30-40 kA/m. The result indicates that the magnetic field and stress have a marked effect on the strain hysteresis of the Tb0.3Dy0.7Fe2 <110> oriented alloy and the hysteresis property of stress-strain relation should be considered during the design of magnetostrictive sensors.
