摘要

The static recrystallisation kinetics of microalloyed steels is a complex matter once strain-induced precipitation has started. This paper analyses the recrystallisation-precipitation interaction in the light of the results of research carried out by Medina et al. in recent years, considering the following aspects: RPTT diagrams in microalloyed steels, its plot and information supplied by diagrams; model for static recrystallisation, which, in addition to the variables that intervene in hot deformation, also takes into account the chemical composition of the steel, both when all the elements are in solution and when the microalloying elements are in precipitated state; model for precipitation kinetics in microalloyed steels, taking into account the influencing variables as the percentage of microalloying elements, strain, temperature, strain rate and grain size; mechanisms of strain-induced precipitation and coalescence of precipitates as the heterogeneous nucleation and Ostwald ripening.
