Strength of Terfenol-D

Description

The strength of the magnetostrictive material, Terfenol-D, Tb/sub 0.27/Dy/sub 0.73/Fe/sub 2.0/, has been evaluated by measuring the modulus of rupture as a function of the Fe stoichiometry of the compound. It is shown that the strength improves markedly as the Fe concentration decreases from the stoichiometric value of 2.0 in the compound. The increased strength results from the increasing volume fraction of the rare-earth metal phase produced in the Terfenol-D matrix by the solidification process at lower Fe concentrations
