It is shown that bending stresses detrimentally affect magnetic losses in Fe-Si ribbons at all frequencies, to an extent that is minimum at 6.7 wt% Si concentration. A magnetoelastically induced redistribution of the domains among the easy axes is assumed to be the leading cause for the observed extra losses upon bending. Addition of 0.15 wt% Mn, while not affecting the magnetic properties, is shown to improve the mechanical behavior of the relatively brittle low-loss high-Si alloys.

Abstract

It is shown that bending stresses detrimentally affect magnetic losses in Fe-Si ribbons at all frequencies, to an extent that is minimum at 6.7 wt% Si concentration. A magnetoelastically induced redistribution of the domains among the easy axes is assumed to be the leading cause for the observed extra losses upon bending. Addition of 0.15 wt% Mn, while not affecting the magnetic properties, is shown to improve the mechanical behavior of the relatively brittle low-loss high-Si alloys.
