Hot Forging of Porous Preforms in a Closed Die with Cone-Shaped Flash Gouge: Numerical Simulation

Abstract

The results from numerical simulation of hot forging of porous preforms in a closed die with cone-shaped flash gouge are presented. Substantial difference in the distribution of deformation and density over the forged piece cross-section at different stages of the process is noticed. It is shown that that the maximum values of both axial and radial strains, as well as intermediate density value,s are concentrated in the zone adjacent to the location of compensation aperture.
