ABSTRACT The microstructure evolution of ferrite in a low carbon steel during hot uniaxial compression tests at 700℃ at 10-2s-1 was investigated by means of optical microscopy (OM), scanning electron microscopy (SEM), electron back scattering diffraction (EBSD) and transmission electron microscopy (TEM). In order to understand the effect of cementite particles size on dynamic recrystallization (DRX) of ferrite, two different microstructures consisting of similar size ferrite and different size cementite particles were adopted by quenching and tempering of a low carbon steel. The results showed that large cementite particles acted as nucleation sites for dynamic recrystallization of ferrite by particle-stimulated nucleation mechanism (PSN), due to the large orientation gradient near them during hot deformation. In the earlier stage, DRX nuclei were mainly formed near cementite particles large than 1m. With increasing strain, they would also be formed near particles between 0.5 to 1m. On the contrary, because of much smaller orientation gradient and pinning effect on the movement of the dislocation and sub-boundary, the cementite particles smaller than 0.3m retarded dynamic recovery and dynamic recrystallization of ferrite.

With a reasonable mesh-induced anisotropy, phase-field simulation is performed to investigate the effect of the diffusional interaction between the particles on precipitates morphologies and inside compositions without taking elastic interaction into account. Simulated results show that, precipitate-morphology transition will occur during growth and coarsening of the precipitate due to the interaction. The initially rounded particle may vary in the sequence of: circular square circular rhombic circular, and the composition of precipitate will become inhomogeneous. With increase of the precipitate volume fraction, the influence of the inter-particle diffusional interaction on the precipitate morphology and the composition will become stronger.
