 Primary precipitates are formed in the liquid state. The //MatCalc// precipitation models are not designed for liquid phase precipitation since its growth models have been developed for diffusion in the solid state. Convection and particle collisions in the liquid state are not accounted for. However, in order to take primary precipitation into account in the simulations, some workarounds can be applied to be able to account for this type of precipitates at least in an approximate way. Primary precipitates are formed in the liquid state.

-The most straightforward means to determine (or estimate) the amount of primary precipitation is the application of the Scheil-Gulliver model. It is described in some detail in the technical paper [[techpapers:equilib:scheil | Scheil-Gulliver analysis with back-diffusion and solid-solid transformations]] and the comprehensive example [[examples:equilib:E20 | Thermodynamic equilibrium analysis for continuous casting simulation of micro-alloyed Fe-Al-C-N-Nb-Ti steel]].+The most straightforward means to determine (or estimate) the amount of primary precipitation is the application of the Scheil-Gulliver model.
