Abstract
Results of microstructural analysis quantified changes in the dispersion phase in Cr-Mo-V weld metal during exposure in the sub-creep range are presented. The hypothesis that changes in the dispersion of MX particles during long-term heat exposure are significant has been confirmed by presented results.
 
 
Keywords: CrMoV steel welds, sub-creep range, secondary hardening, vanadium carbides and carbonitrides, microstructural analysis, image analysis
