Modelling has proven to be an efficient way of cutting time and costs associated with the investigation of materials properties. Two examples of thermodynamic modelling are presented which describe different phenomena in steels: the precipitation of carbonitrides and Ti‐based inclusions in IF steels, and the coarsening of dispersed phases in HSLA steels. The underlying mode of describing the phases is the Calphad method, which has been combined with diffusion calculations to give results from both microscopic and macroscopic statistical points of view. The results of the calculations show a good agreement with the experimental data available in literature, and the methodology may be considered as illustrative and extendible to a variety of similar cases.
