Precipitation of carbonitride in HSLA steel containing up to three microalloying elements was analysed, using classical theory of diffusion controlled nucleation. For this purpose the driving force for carbonitride nucleation is calculated using a thermodynamic model. The results of calculation show, that the critical nucleus formed at high temperature is richer in N and element having the highest chemical affinity for N compare to the bulk precipitate at equilibrium. On the basis of analysis a kinetic model was developed for predicting start times, for precipitation of carbonitride in austenite.
