摘要 | orient-ed Tb0.3Dy0.7 (Fe1-xAlx)2 (x=0, 0.05, 0.10, 0.15) alloy was prepared by the method of zone-melting directional solidification and then annealed at 930°C for 2 h. The effect of heat treatment on microstructure, magnetostriction and mechanical properties of the Tb0.3Dy0.7 (Fe1-xAlx)2 alloy was investigated. The results show that the primary phases of Tb0.3Dy0.7 (Fe1-xAlx)2 alloy are the MgCu2-type cubic laves phase as well as some RE-rich phase structure and the unchange of the axial preferred orientation is observed by the heat treatment. With the increasing of Al content, there are some RE(FeAl)2 phase and RE(Al) phase precipitatied from the REFe2 matrix, and the morphology and distribution of the precipitated phase varys with the heat treatment, while the lamellar microstructure is degraded and the resistance of magnetic domain rotation for REFe2 phase is reduced. The magnetization and magnetostriction measurements show that heat treatment decreases the saturation magnetostriction of the Tb0.3Dy0.7 (Fe1-xAlx)2 alloy (x=0.05, 0.15), and the saturation magnetostriction are 817×10-6, 571×10-6, respectively. Compression strength and low-field dynamic response of the Tb0.3Dy0.7 (Fe1-xAlx)2 alloy (x=0.10) are significantly improved after heat treatment at 930°C for 2 h and no reduction of saturation magnetostriction is detected. |
