Abstract

Effects of isothermal transformation temperature on amount of retained austenite and its thermal stability in a bainitic Fe-3%Si-0.45%C-X steel was analyzed. Film-like morphology of retained austenite was observed at low isothermal temperatures and blocky morphology of retained austenite appeared at high temperatures in a bainitic Fe-3%Si-0.45%C-X steel. The results showed that amount of retained austenite increased with increasing temperature and exhibited a peak at around 350°C, above which it decreased with increasing temperature.
