This article examines the effect of the strain-hardening parameters of a deformable material on the strain distribution in a product obtained by upsetting. The study was conducted with the use of materials having different types of strain-hardening curves. Results obtained by modeling and an experiment show the uniformity of the strain distribution.
Heat treatment parameters providing a required level of mechanical properties for different component parts are determined on the basis of experimental data about supercooled austenite transformation in engineering chromium-molybdenum steel, and also results of numerical modeling of variable cross-section components of this steel in a QForm 7 program.
