Comparison of results of dynamic recrystallization research of HC420lA steel by two types of tests on Gleeble 3800
The article shows an influence of kind of tests on material hot defamation behaviour during physical modelling on
Gleeble 3800. As material, high-strength low-alloy automobile steel HC420LA was used. Stress-strain curves and material constants based on results of flow stress and plain strain tests were calculated and compared. Besides finite-element modeling of rolling round bar on a smooth barrel was performed taking into account the calculated mechanical characteristics.
