Abstract

In this work the microstructural stability as a consequence of heat treatments and welding processes has been investigated for different DSSs. Three main topics was developed. The decomposition of the ferritic phase has been studied in isothermally aged SAF 2507 SDSS. The effects of laser beam welding on SAF 2507 SDSS previously cold rolled. The effect of backing gas composition on lean duplex grades LDX 2101 and LDX 2404 welded with GMAW process
