Abstract

Abstract: Preparing method and processing of Tb-Dy-Fe alloy samples with [(1) over bar 10] axial orientation as well as their magnetostrictive properties have been studied. It has been found that the magnetostrictive strains of polycrystal samples with [(1) over bar 10] axial orientation can reach (1550 similar to 1900) x 10(-6) in a low magnetic field less than 80 kA/m, which are equal to or somewhat better than that of the polycrystal samples with [11 (2) over bar] axial orientation.
