Abstract:

The paper focuses on the modelling of MX-type carbides precipitation processes in low-carbon precipitation strengthend bainitic steels. The precipitation of these carbides allows the lowering of carbon content in bainitic steels, while maintaining their strength. In this way, high strength and ductility in long and flat products can be developed by means of proper thermo-mechanical processing. Deschamps model was employed to simulate the precipitation kinetics under the assumption that the diffusion along dislocation line is the rate controlling process. The elaborated model was used to evaluate the effect of steel composition and process parameters on the precipitation strengthening effect.
