Abstract

This work is devoted to the study of stress-strain state and power parameters in the simulation of the process of extrusion billets with additional back-pressure in equal channel step matrix. Analyzing the obtained results we can conclude that the matrix without backpressure cannot achieve complete closing of internal defects of a deformable metal. The backpressure created by the increase of the roughness of the output channel of the matrix, has a beneficial effect on the stress-strain state of the metal, which in turn allows you to provide the best structured deformable metal
