Popis: With a high silicon content, silicon steel has good soft magnetic properties because of the decreased magnetic anisotropy, lower magnetostriction and higher resistivity. However, above 3.5 wt.% Si a lower ductility makes conventional processing into textured strips extremely difficult. In this investigation we consider another possible method which consists of depositing silicon and aluminium on a pure iron substrate by chemical vapour deposition. The magnetomechanical damping evolution (measured at 0.7 Hz with a torsional pendulum) of enriched iron strips containing between 0.5 and 5.5 wt.% Si + Al is considered. Results show a strong decrease in magnetomechanical damping with increasing Si + Al content, which coexists with a lowering of the magnetic core losses measured at 50 and 400 Hz. Results relative to as-prepared and homogenized states are compared.
