A. Ali et al., INCOMPLETE REACTION PHENOMENON IN HIGH-STRENGTH BAINITIC STEELS, Metallurgical transactions. A, Physical metallurgy and materials science, 24(10), 1993, pp. 2145-2150
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.
