The redistribution of interstitials (C, N) and phase profiles in heterogeneous laboratory weldjoints of the 6CrMoV 8-3-2 and X12CrMoVNb 10-1 nitrided heat-resistant steels were calculated. For the calculations Thermo-Calc and DICTRA software packages were ušed. The results from the simulation were compared with experimental observations. A relatively good agreement between the simulation and the experiments was observed.
