Abstract	The phase relationship of Tb_0.26Dy_0.49Ho_0.25Fe_x (1.6 ≤ × ≤ 2.4) alloys in the Tb-Dy-Ho-Fe system was determined by using optical microscopy, X-ray diffraction, and differential thermal analysis. The vertical section of Tb_0.26Dy_0.49Ho_0.25Fe_x alloys consists of two single-phase regions, namely, L (liquid) and (Tb, Dy, Ho)Fe₂, and four two-phase regions, namely, L + (Tb, Dy, Ho)Fe₃, L + (Tb, Dy, Ho)Fe₂, (Tb, Dy, Ho)Fe₂ + (Tb, Dy, Ho)Fe₃, and (Tb, Dy, Ho)Fe₂ + (Tb, Dy, Ho). The range between the liquidus and peritectic temperatures for Tb_0.26Dy_0.49Ho_0.25Fe_x alloys becomes narrow with addition of Ho, which is beneficial to decrease the properitectic (Tb, Dy, Ho)Fe₃ phase. The magnetic field dependence of magnetostriction (λ_//, λ_⊥) for Tb_0.26Dy_0.49Ho_0.25Fe_x alloys has been determined. The magnetostriction quickly increases with increasing magnetic field value when it is less than 240 kA/m. Among the present studied alloys, the sample with x = 1.9 possesses the largest magnetostriction. It has been found that magnetic annealing improves the magnetostriction λ_// of Tb_0.26Dy_0.49Ho_0.25Fe_1.9 alloy.
