Abstract The structure and magnetostriction of Dy_0.9-xTb_xPr_0.1Fe_1.85 and Dy_0.9-xTb_xPr_0.1(Fe_0.95Al_0.05)_1.8 alloys were investigated. These alloys are substantially single phase with MgCu₂-type cubic structure. The lattice parameter and Curie temperature of Dy_0.9-xTb_xPr_0.1(Fe_0.95Al_0.05)_1.8 alloys increase steadily with increasing Tb content. Tb dependence of magnetostriction in various applied fields for polycrystalline Dy_0.9-xTb_xPr_0.1Fe_l.85 alloys exhibits a peak at x = 0.25. The magnetostriction of polycrystalline Dy_0.9-xTb_xPr_0.1(Fe_0.95Al_0.05)_1.8 alloys in high applied fields (H > 160 kA/m) and in low applied fields (H≤ 160 kA/m) exhibits a peak at x = 0.3 and x = 0.25, respectively.
