This paper presents an analytical model to describe the precipitation kinetics during isothermal holding following high temperature deformation in Ti micro-alloyed steels. This model was based on the classical nucleation and growth theory (CNGT) and Avrami equation. Using this model, the precipitation-time-temperature (PTT) diagrams for the kinetics of precipitation were easily obtained, and results show a good agreement between the experimental observation and the predictions of the model in terms of the characteristics of the PTT curves, including the shape and nose temperature and chemical composition dependence.
