HOT FORGING OF POROUS PREFORMS IN A CLOSED DIE WITH A CONE-SHAPED FLASH GUTTER: NUMERICAL SIMULATION

摘要

The hot forging of porous preforms in a closed die with a cone-shaped flash gutter is numerically simulated. The cross-sectional distribution of strains and density over the preform substantially differs at various stages of the process. The maximum axial and radial strains, as well as intermediate density values, are observed near the flash gap.
