Dynamic recrystallization mechanisms of an Fe-8% Al low density steel under hot rolling conditions

Abstract : Iron-aluminium alloys display promising physical and mechanical properties. In this study, the effects of strain, strain rate and temperature on an Fe-8% Al were investigated. Hot torsion tests were performed in the temperature range 900-1100 degrees C and strain rate range 0.1-10 s(-1). In this alloy, two types of dynamic recrystallization may operate during hot deformation: at high temperature and high strain rate, this alloy undergoes discontinuous dynamic recrystallization, whereas at lower temperature and strain rate, continuous dynamic recrystallization occurs.
