Degradation of welded joint made of T91 steel with different additional materials
##plugins.themes.bootstrap3.article.main##
Abstrakt
The aim of the research was to analyse the processes of degradation observed in a dissimilar welded joint of T91 steel. The analysis was performed for welded joints after long-term annealing for up to 8000 hours at the temperature of 600oC. Microstructural analysis and hardness testing were performed. The purpose of the tests was to evaluate the effect of annealing time at the temperature of ageing on formation and properties of the decarburized zone in the inter-bead area of the welded joint.The aim of the research was to analyse the processes of degradation observed in a dissimilar welded joint of T91 steel.
