Abstract
Phase equilibria between the fee matrix and the hcp nitride phase were installed by long-time heat treatment at 1273 and 1073 K, respectivel y, in different Fe-Cr-Mn-N alloys. The composition of the phases was d etermined applying wavelength-dispersive X-ray microanalysis. The resu lts are compared with thermodynamic calculations using published data describing the fee and the hcp phases in the system Fe-Cr-Mn-N. The ag reement is satisfactory at medium concentrations at 1273 K but there a re considerable differences at 1073 K.
