Some standard applications: Calculations of multi-component phase equilibria and thermokinetic precipitation simulations in tool steels, micro-alloyed steels, 9-12% Cr-steels, PH maraging steels, austenitic stainless steels.

Special simulations: Coupled nitride/sulfide precipitation in micro-alloyed steels, early precipitation of carbon clusters in tempered martensite, gamma´-precipitation in Ti-alloyed irradiated austenitic steels.
