Abstract
Bainite forms by a displacive transformation mechanism and exhibits an incomplete reaction phenomenon. The kinetics and mechanism of bainite transformation have been studied in high-strength Fe-C-Si-Mn and Fe-C -Si-Ni steels using high-speed dilatometry. The new experiments report ed here confirm the incomplete reaction phenomenon. with the bainite t ransformation stopping well before paraequilibrium is achieved. These results show that bainite probably grows without diffusion, but soon a fterwards, excess carbon is partitioned into the residual austenite.
