FIELD: metallurgy.
SUBSTANCE: invention relates to metal deformation process with usage of severe plastic deformation and can be used while receiving of nanocrystalline material with increased level of mechanical properties. Punch for equally-channel angular pressing contains band, ground base and compression ram. Into band is pressed in conic insert made from several detail. Walls of access port are formed by parts of mutually perpendicular flat surfaces of these details, closed to each other. The first of output channel walls is formed by part of mutually perpendicular flat surface of detail, which has the other part of this surface as wall of access port. The second wall of output channel is formed by part of ground base surface, which is closed by this surface with butt ends of all details base. The third and the fourth walls of output channel are formed by two mutually perpendicular surfaces, cutting off part of the second detail of insertion.
EFFECT: punch stiffening effect and its design simplification.
