Description
  • The structural changes taking place in the dissimilar laboratory welds of 6CrMoV 8-3-2 (T25), being under development, and modified X12CrMoVNb 10-1 (P91) nitrided steels annealed at temperatures of 500-900stC have been subject of study. Carbon and nitrogen redistribution measurement by the EPMA method was complemented with detailed structural analysis aimed at the phase profiles and chemical composition of coexisting carbides and carbonitrides in particular regions of the weld joint. Results of experimental work were compared with thermodynamic and kinetic modelling using the DICTRA software. A very good agreement between the modelling and the experiments was observed.

  • Předmětem studia byly strukturní změny v heterogennním svarovém spoji nově vyvíjené oceli 6CrMoV 8-3-2 a modifikované X12CrMoVNb 10-1. Obě oceli byly před svařením nitridovány pro zvýšení obsahu dusíku. Po svaření proběhlo žíhání spoje při 500, 600 a 900stC. Redistribuce uhlíku a dusíku měřená vlnově disperzní mikroanalýzou a zjištěné fázové složení byly porovnány s kinetickými simulacemi provedenými s využitím softwaru DICTRA. Mezi experimentem a výpočtem byla pozorována velmi dobrá shoda. (cs)
