Bainite Transformation in Experimental Fe-Cr-Mo-V-Ti-C Steel

Ławrynowicz Z.

Advances in Materials Science

2013

Vol. 13, nr 2(36)

12--18

The mechanism and kinetics of bainite transformation have been studied in Fe-Cr-Mo-V-Ti-C steel using high speed dilatometry and transmission electron microscopy (TEM) backed by thermodynamic analysis. At any temperature investigated did not occur the complete transformation of austenite. Obtained results confirm the incomplete reaction phenomenon with the cessation of the bainite transformation well before paraequilibrium is achieved. These experimental data indicate that bainitic ferrite forms by a displacive transformation mechanism, but soon afterwards, excess of carbon is partitioned into the residual austenite.

The paper presents an investigation of the mechanism of bainite transformation in 0.2C-1V-2Mn steel using high speed dilatometry and TEM backed by thermodynamic analysis. Obtained results confirm the incomplete reaction phenomenon with the cessation of the bainite transformation well before paraequilibrium is achieved. These experimental data indicate that bainitic ferrite forms by a displacive transformation mechanism, but soon afterwards, excess of carbon is partitioned into the residual austenite. The results are discussed in terms of the mechanism of bainite transformation.
