Abstract

On the basis of simulation with the help of the QFORM VX software, we study the CONFORM process with an aim to eliminate the delamination defects of products in the course of subsequent heat treatment. In the first stage of the solution, it is necessary to determine the stress-strain state in the deformation zone in the billet and to analyze the behavior of the flow of metal and the appearance of the zones of hindered deformation.
