Zusammenfassung:A method of forging axisymmetric articles by local deformation consists in a cyclic upset along a circle by a narrow striker of a cylindrical workpiece, which is aligned with its rotation around axis for an angle that provides the coverage by a striker of a part of deformation site of the previous local upset. First a narrow striker is used for upsetting an annular peripheral part with an inner radius of L1 = (0.2-0.3) Dwith a diameter Dto the thickness H1 = (1,1-1,3) Hp followed by local sequential upsetting the central and peripheral portions of the semi-finished product to the thickness Hp by a shaping narrow striker, and the striker has a bulge in the central part with a radius R
