For the production of structural steel with a nanostructure there are used methods combined into five groups – powder metallurgy, amorphous state crystallization, intensive plastic deformation, surface and volumetric thermo-deformation treatment. The last method is the most effective one for products subjected to cyclic loads and destructed because of fatigue. A limited longevity at loads exceeding fatigue strength increases ten times and more. A thermo-deformation working is carried out at the production of cylindrical spiral springs, cylindrical parts – shafts, axles, mill rollers.
