Approvement of 'Tension-Compression' Technique Developed for Physical Simulation of Multistage Metal Plastic Deformation Processing

摘要

There are a number of techniques for physical simulation of multistage metal plastic deformation processes. Analysis of these techniques in terms of stress-strain state schemes is presented. The purpose of described research is to compare microstructure and mechanical properties of two pipe steels processed by laboratory rolling mill with microstructure and mechanical properties of the same steels processed by thermomechanical simulator Gleeble-3800 with four different mobile convert units (MCU): MaxStrain, Torsion, HydraWedge and Pocket Jaw. Obtained results clearly show that proposed "tension-compression" technique developed for Gleeble Pocket Jaw MCU is theoretically and experimentally proved and can be successfully used for simulation of complex multistage metal plastic deformation processes, such as rolling, forging, stamping, etc.
