Magnetostriction of field-structural composite with Terfenol-D particles
The paper describes the magnetomechanical properties of magnetostrictive composites containing a 70% volume fraction of Terfenol-D powder. Except for a reference specimen, composites were subjected to polarization during curing of the resin. The results of tests showed that polarization, its direction and type have an effect on the properties of the produced composites. The highest values of magnetostriction from the manufactured composite samples were obtained for the perpendicularly polarized specimen. For a pre-stress of 7 MPa the strain amounted to 720 ppm. The results indicate that the magnetostriction of the composite increases owing not only to the proper crystallographic orientation of the material, which is usually [1 1 2], but also to the proper preparation of the specimen in this case through polarization.
