The present invention provides preparation process of TbDyFe-base magnetostrictive alloy. The technological process includes preparing mother alloy in a cold crucible inducing furnace with high efficiency and high mother bar quality; and several heater structure are designed for directional solidification with resistive heater. By means of preparing crystals of different diameters, several times of directional solidification and simultaneous directional solidification of several mother rods, the present invention has high crystal preparing efficiency and quality and develops high efficiency magnetic field heat treating method. |
