Abstract
The magnetostriction alloys of the present invention are composed basically of Tb--Dy-iron which is partially substituted by at least one element selected from the group consisting of Y, La, Ce, Pr, Nd and Sm, and have been grown in the direction of face index <110> or contain Mn and M element (at least one metallic element selected from the group consisting of C, Mg, Al, Si, Ca, Zr, Y, Ga and B. The magnetostrictive alloy may be formed by melting the constituent materials by high frequency induction dissolution. The molten materials are cast in a heated mold having a temperature gradient. The solidified material may be further treated by hot working.
