Butter-weld Interface Microstructural Analysis Employing NCS and LAMS Sections

Abstract: The formation of brittle microstructures around the fusion line in dissimilar welds has required a deeper microstructural analysis in this region. The study becomes more relevant when these welds are used in environments that facilitate hydrogen embrittlement. The present work aims to characterize the microstructure and hardness at the diluted zone interface in joints welded with dissimilar materials. Aiming for a better efficacy in the microstructural characterization of this zone, samples of both normal cros… Show more

“…Figure 10a and b, shows images extracted by the LAMS technique 18 , showing macrosegregations of "island" and "swirl" type, with some of the microhardness values surveyed at the dissimilar interface, which is also shown in Table 9. Within the red rectangle of Figure 10b, there are dark regions, on the steel side, known as M zones.…”
