Název v původním jazyce

Study of the dispersion phase weld metal of 0,5%Cr-0,5%Mo-0,3%V sted after long-therm heat exposure in the sub-creep range.

Popis výsledku v původním jazyce

The mechanical properties of type 0,5%Cr-0,5%Mo-0,3%V steels are affected in particular by the parameters of the dispersion phase, namely vanadium carbides and carbonitrides MX. The dispersion of MX particles occurs during steel tempering and subsequentlong-term heat exposure causes changes in the number, mean size and mean spacing of particles. These changes significantly influence the material´s mechanical peoperties. Operation in the sub-creep region gives rise to secondary hardening, accompanied bya degradation of plastic properties. This hardening is pronounced especially in weld joints that were tempered at temperatures which were lower than is required by industry standard. This article presents the results of a microstructural analysis which quantifies changes in the dispersion phase in weld metal during exposure in the sub-creep range. The hypothesis that changes occur in the dispersion of the minority phase of weld metal of 15 128 steel during long-term heat exposure in the
