| In this study, AISI 420 martensitic stainless steel to AISI 2205 duplex stainless steel sheets were joined with laser welding. Post-weld heat treatment was applied to a laser-welded joint. Microhardness, tensile, and impact tests were carried out to determine mechanical properties of a welded joint. Microstructure characterization was performed in a detailed way by using macroscope, optical microscope, SEM-EDS, XRD, and EBSD analyses. The results indicate that retained austenite phase fraction increased with the effect of heat treatment in the microstructure of martensitic stainless steel, and austenite phase fraction increased in the microstructure of duplex stainless steel. They also show that tensile strength of heat-treated martensitic and duplex stainless steel base metals, and heat-treated welded joint improved, but their impact toughness decreased. However, tensile strength of welded joint was lower in comparison with base metal. Chromium-carbide (Cr |
