The purpose of research is to develop new ways of resource forging of large forgings, stampings, local deformation of high-precision parts of high quality on the basis of calculation methods and develop new methods of plastic deformation that expand the technological capabilities of processes of forging, stamping and local deformation in the frictional heating due to optimization technological regimes and reduce material costs. The basis of the theoretical research on the method's of the upper bound and finite element method. The technique of experimental studies designed and constructed experimental equipment and supplies, as well as received samples and blanks for research. Get models are combined reverse tapered extrusion parts, upset process of the inner flange of the tubular blank, estimated strain state stepped in broaching the strikers, and a calculation of temperature and power settings of the local deformation of the tubular blank with frictional heating. Application domain: forging, stamping, local deformation. The experimental results based on compression were drawn curve of stress strain. It is considered that the material used in twist extrusion process has high mechanical properties. The workpiece that used on die with different angles is allowed to intensify the shear strain deformation in workpiece. The schemes by workpiece on die with different angles and on combined asymmetric dies to reduce the inhomogeneous distribution of shear strain with the cross section of the workpiece are defined. It is considered that thermal control in workpiece to the forging processes allows the influence in the stress-strain state of the workpiece.
