摘要：

The paper presents application of multistage compression test for modelling of hot rolling of various steel products. To carry out these experiments multifunctional deformation simulators Gleeble of different types have been used. Results of this work show that the flow stress data can be obtained for high strain values, much higher than can be acquired in torsional tests. Thus, conditions of Gleeble tests are more close to industrial condition and data (flow stresses) obtained from Gleeble simulation are more realistic. Apart from that, the compression tests realized in the investigation aimed at identification of grain size evolution and hardening or softening behaviour as function of temperature, strain, strain rate and idle time between deformations. Physical modelling using multistage compression tests provides basics for the analysing and designing of hot rolling processes of various products and allows to learn more about metal properties in deformation conditions.
