“…At the same time, it has been established that the achieved density is not the only criterion that determines the formation of the structure and properties of the metal. Depending on the stress–strain state during deformation, for the same final density of the powder metal the microstructure, plastic properties and, especially, impact strength also change significantly [17–20].…”

Comparative results of numerical simulation of the process of hot forging of porous preforms with an axial hole for two deformation schemes are presented: in a die with a flash groove on the inner surface of the forged workpiece cavity and in a closed die. A significant difference in the nature of the evolution of the distribution of deformations and density over the crosssection of the workpiece for the two considered schemes is noted. It is shown that forging in a die with an open volume provides significantly higher degrees of material deformation during forging compared to closed forging, which should lead to an increase in the quality of the structure and final properties of the forged material.
