摘要：
The < 110 > grain oriented alloy was grown by zone melting directional solidification technique. The strain-stress curves of Tb0.3Dy0.7Fe2 < 110 > oriented alloy in different magnetic fields have been measured and the magnetic field dependence of Young's modulus under different compressive stress has been confirmed. It is found that Young's modulus gradually decreases with increasing the magnetic fields when the compressive stress is in the range of 15-25 MPa and changes a little in the range of 40-50 MPa. The experimental result indicates that the magnetic field has a marked effect on the Young's modulus of the Tb0.3Dy0.7Fe2 < 110 > oriented alloy at a low compressive stress and its change should be considered during the design of magnetostrictive devices.
