Abstract
The Fe-21 %Cr-17,5 %Mn alloys with different nickel and nitrogen contents w ere prepared at controlled nitrogen activity. Phase equilibria after long t ime annealing at 1073K and 1273K were investigated using optical metallogra phy, scanning electron microscopy and transmission electron microscopy. The two- and three-phase equilibria combined from fee, bcc, sigma phase, and f rom Cr-nitrides type hcp were identified. The obtained experimental results were compared with predicted phase diagrams of the Fe-Cr-Mn-Ni-N system ca lculated by means of the CALPHAD method.
