PROSPECTS FOR APPLYING LASER-MECHANICAL METHODS TO THE IMPROVEMENT OF THE PHYSICAL PROPERTIES OF TRANSFORMER STEEL
The influence of the (110)  edge crystallographic textures on the prospects of reducing magnetic losses in local laser processing, mechanical scribing and local bending, solving the problem of improving the functional characteristics of Fe–3 % Si anisotropic magnets and amorphous alloys, is investigated. It is shown that the complex effect of laser treatment and subsequent thermo magnetic treatment in an alternating magnetic field makes it possible to reduce the magnetic losses of P1.7/50 in steels of higher grades with an edge texture close to the optimal one (grade 3409, B800 = 1.93 T) by 14–18 % and 18–26 % in a thin amorphous ribbon of the Fe81Si7B12 alloy.
