摘要	The oriented 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. The effects of substituting Al for Fe on the microstructure, magnetostriction and mechanical properties were systemically investigated. The results show that the primary phase of Tb0.3Dy0.7 (Fe1-xAlx)2 alloy were MgCu2-type cubic Laves phase structure and some RE phase, and the Al substitution doesn't change the axial preferred orientation. With the increase of Al content, there are some RE(FeAl)2 phase and RE(Al) phase precipitated from the REFe2 matrix, and the quantity, size and distribution of the second phase vary with Al content increasing. The magnetization and magnetostriction measurements show that a small amount of Al substitution (x≤0.05) is beneficial to a decrease in the magneto crystalline anisotropy, and the saturation magnetostriction and dynamic response in low magnetic field increase drastically. With the increase of Al content, the saturation magnetostriction decreases distinctly, while the compressive strength increases. The fracture of the Tb0.3Dy0.7 (Fe1-xAlx)2 alloy is cleavage fracture. The alloy with Al substitution range from 0 to 0.1 has optimal performances.
