Abstract

AbstractResults of the effect of deformation parameters on the hot-deformation behavior and softening kinetics of two Ti–V–B-microalloyed steels were presented in the paper. The investigated steels are assigned to production of forged elements for the automotive industry by thermo-mechanical treatment. Research was conducted by compression test at elevated temperature. Hot compression test was performed using the Gleeble 3800 thermomechanical simulator at the temperature range from 900°C to 1100°C and strain rate of 1, 10 and 50s−1. The σ–ε curves were determined on the basis of continuous compression and double-hit compression tests.
