Constructional steels processing by combine impact of extrusion and screw pressing

Impact of combined processing by extrusion and screw pressing on structure, mechanical properties and fracture mechanism in constructional steels is considered. It is shown that the specified type of processing leads to increase the strength characteristics that is connected with grains crushing and increase the density of dislocations. It is established that reliefs of breaks of steel samples after the combined deformation have no considerable differences in comparison with an initial state, and fracture of samples has happened on the viscous mechanism.
