Abstract

The present disclosure is directed to an energy conversion device that is adapted to convert magnetic energy into mechanical energy. The device includes a generator that is adapted to generate a magnetic field. The device also includes a body centered cubic crystalline alloy that can be subjected to the magnetic field generated by the magnetic field generator. The alloy has a room temperature saturation magnetostriction of at least 50 or 90 ppm along the [100] axis of the alloy crystals. The alloy includes a large atomic % of Fe. The alloy can also include Mo, W, or Cr. The alloy is adapted to convert magnetic energy into mechanical energy in the form of a change of dimension of the alloy when subjected to the magnetic field.
