| Abstract |
Industrial thermomechanical processing of hot rolled steel strip products with rolling
operations in the austenite + ferrite (γ + α) range offers, on one hand, unique possibilities for more
precise control of microstructure and mechanical properties of as hot rolled products after
accelerated cooling. On the other hand, there are significant technical problems related to the rolling
stability induced by steel grade dependent non-monotonous variations in deformation resistance and
its sensitivities to temperature and strain rate within the γ + α range. Based on laboratory results, the
deformation behavior of low carbon (up to 0.2 %) steels alloyed with Mn, Si, Al and their
combinations, as well as microalloyed with Nb at the intercritical temperatures is discussed. |
