The microstructure evolution and magnetization and magnetostriction properties of Tb0.3Dy0.7Fe1.95 alloy solidified in a high magnetic field were investigated. A cellular microstructure was produced, with the grains highly aligned along the direction of the magnetic field. The (Tb,Dy)Fe2 phase was highly oriented, with its ?1?1?1? axis along the magnetic field direction. The easy magnetization direction of the alloy lay along the magnetic field direction. The magnetostriction at room temperature significantly increased to double that of the sample prepared without high magnetic field; in addition, a sharp rise in the initial magnetostriction at low fields was observed. Applying a high magnetic field during the solidification process is proposed as an effective route for fabricating ?1?1?1? oriented Tb?Dy?Fe compounds, and improving their magnetic and magnetostrictive properties.
