Analysis of the Structure Formation and Properties of the VT6 Alloy during Upsetting of the Symmetrically Truncated Conical Billets

摘要

Based on the results of experimental and theoretical investigations, the parameters of deformation and high-speed hardening for the VT6 alloy at deformation temperatures of 780-940°C and rates from 0.5 x 10~(-3) to 1 s~(-1) are determined. A mathematical model of upsetting for VT6 samples that have a symmetrically truncated conical shape is constructed with the use of Deform3D package. Failures of the stress-strain state at the side surface during upsetting are determined, and a mathematical model of the structure formation is constructed.
