Abstract

Due to its excellent properties, the AL-6XN stainless steel has been proposed as an alternative to replace 316L stainless steel during the repair of components and pipelines used in power plants. Therefore, a deep understanding of the behavior of dissimilar welded joints is needed.  In  this  paper,  the  microstructure  and  mechanical  properties  of  a  dissimilar  joint between AL−6XN and 316L stainless steels welded by the Gas Tungsten Arc Welding (GTAW) process are investigated using  optical  microscopy  (OM)  and  scanning  electron  microscopy  (SEM),  tension  test,  analysis  of  X-rays  dispersive energy (EDX) and microhardness measurements. An analysis of the fracture mode of the tension samples was performed. Tension test results show that welded samples exhibit higher strength, fracture occurs in the heat affected zone (HAZ) of the 316L stainless steel. Microstructural analysis shows the presence of small precipitated titanium particles in the HAZ of the 316L stainless steel.
