What is Microstructure of UNS S43932 Welded Joints about?

This study investigates the microstructure and mechanical properties of 5 mm-thick UNS S43932 steel welded joints under typical heavy fabrication conditions. The research reveals that while the base metal exhibits a large grain size and ductile behavior in tensile tests, both the base material and heat affected zone (HAZ) show low toughness in impact tests. Fracture analysis indicates failure mechanisms include clivage and intergranular fracture, with the latter displaying numerous small precipitates.
