Abstract Scope Metallographic studies were carried out to establish the influence of the microstructure after cold deformation and subsequent processing under conditions of self-propagating high-temperature synthesis (SHS) on the magnetic characteristics of steels, such as coercive force, grain size, and the relative number of unidirectional boundaries. After processing the cold-deformed material under SHS conditions, the grain size decreases from 10.3 μm to 5.22 μm, and the relative number of unidirectional boundaries increased from 23.7% to 37.2%. The fine-fiber structure is the result of elongation and deformation of grains during material drawing, which is confirmed by the high value of the coercive force of 9.4 A/cm. The non-stationary stage of the process of self-propagating high-temperature synthesis, leads to grain refinement and an increase in magnetic permeability. The value of coercive force allows you to control changes in the structure of the wire at all stages of its metallurgical production.
