Original Abstract

. The paper includes the results of a study of structural changes taking place in laboratory weld joints of the 6CrMoV 8-3-2 (T25) and X12CrMoVNb 10-1 (P91) steels annealed at temperatures of 600 and 900 C. The nitrogen content in both steels was increased by ion-nitriding and subsequent homogenization. Carbon and nitrogen redistribution measurement by the EPMA method was complemented with detailed structural analyses aimed at the phase and chemical composition of coexisting carbides and carbonitrides. Results of experimental work were compared with thermodynamic and kinetic calculations using the Thermo-Calc and DICTRA software
