Conclusions

  1. 1.

    Vacuum heat treatment of Fe−Al alloys (10−4 mm Hg) creates stresses favorable for orientation of the domain structure to obtain high values of magnetostriction.

     
  2. 2.

    Heat treatment in hydrogen leads to an unstressed domain structure with predominance of 180° boundaries.

     
  3. 3.

    The carbide phase in alloys with 0.09% C distorts and refines the domain structure throughout the bulk of the sample, although conditions for increasing the magnetostriction are not ensured in this case.
