Considerations on the Effect of Plastic Deformation Over the Magnetic Behavior of Soft Ferromagnetic alloy FE-3%SI NO

Abstract

The paper synthetically presents the results obtained over the degradation of magnetic properties of soft ferromagnetic sheets Fe-3%Si NO required mechanically in plastic deformation area. Chronologically, the evolution of magnetic behavior was considered from two complementary approaches: after plastic deformation and, recently, during a uniaxial traction/pull. The analyze of the behavior refers firstly to the structure of dislocation and, secondly, to the level of internal tensions generated during cold hammering..
