FIELD: technological processes.
SUBSTANCE: residual stresses are formed in the axisymmetric plastic deformation of the article by means of a deforming tool with a conical working part. Residual voltages are formed at a relative reduction of 1.0%. Residual compressive stresses are formed in the peripheral layers of the article to a depth of 0.3R, where R is the product radius and residual tensile stresses in the central region of the article by creating a tensile force greater than the axial compression force.
EFFECT: rigidity of the products increases.
