Placing particles such as Terfenol-D in a polymeric resin will a magnetostrictive effect and at the same time reduce the disadvantages of the monolithic material.
In most of these papers, the thermosetting resin was used as binder in the process of compaction of the Terfenol-D to obtain the final material.
The composites were prepared using the same experimental process by adding Terfenol-D powders 1 h after the reaction started, to get a homogenous material.
9 and 10, the thermograms of the neat polyurethanes are compared to composites containing 30-70 wt% of Terfenol-D magnetostrictive particles, respectively.
The glass transition temperature increased with the increase in Terfenol-D content.
1], directed through terfenol-D rod 3 and trough the left side of plates 2 and 5.
The strain of the terfenol-D rod depends on a rod length and the flux [[PHI].
For small variations of the magnetic flux inside the terfenol-D the dependence of magnetostrictive displacement vs.
The distribution of the magnetic flux density axial component By along the terfenol-D rod in relation to air gap [DELTA] was obtained.
The name Terfenol-D is derived from terbium; Fe, the chemical symbol for iron; the Naval Ordnance Laboratory; and dysprosium.
During manufacture, Terfenol-D is melted, cast, and directionally solidified to provide the crystalline microstructure required to produce large strains.
Another advantage is the fact that the continuous cycling of Terfenol-D through its temperature range has no effect on its magnetostrictive performance, even if its Curie temperature is exceeded.
