Important relations between the volume fractions of phases and the time of service, especially the precipitation of intermetallics need to be revealed. The present study describes the time depedence of the structure development of two corrosion resistant steels with chromium content of 27 and 32 wt.% and various additions of nickel, molybdenum, manganese, silicon, copper and nitrogen. The microstructure was studied on samples annealed at 700oC for 500, 3188 and 6170 h, revealing the kinetics of the equilibrium process. The homogenity of samples was checked before heat treatment. The experimental microstructures are compared with the predicted phase composition. The effect of using different databases is also discussed.
