Using the simulation results it was shown an optimal correlation of the size and porosity of powder compacts and also the amount of counterpressure recommended for the production of equal channel angular extrusion of workpieces with high-density of deformation zone that is large enough for subsequent direct extrusion powder of parts with high mechanical properties.The article defines the maximum depth of the cavity in direct extrusion through the research of plasticity resource. This paper describes the developed technology of manufacturing high-density parts of the "glass" type with the consistent application of the equalchannel angular and direct extrusion.
