Description It is described the time dependence 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 700 oC for 500, 3188 and 6170 h, revealing the kinetics of the equilibrium process. The experimental microstructures are compared with the predicted phase composition. The effect of using of different databases is also discussed.
