Abstract
The effect of severe plastic deformation on the microstructure and magnetic properties of a soft magnetic precision alloy 27KKh has been studied. Severe plastic deformation by equal-channel angular pressing has been used. It has been shown that equal-channel angular pressing that forms a fine-grain structure of the material leads to its magnetic hardening. The annealing of strongly deformed samples made it possible to significantly improve the magnetic characteristics. The magnetic permeability was increased by more than three times compared to the treatment that is carried out according to GOST State Standard 10160–75.
