1. Super duplex stainless steels : Microstructure and propertiesof physically simulated base and weld metal
Abstract : High-temperature processing and application of super duplex stainless steel(SDSS) are associated with the risk of changes in the ferrite/austenite balance and precipitation of secondary phases. This study was therefore aimed at improving knowledge about effects of thermal cycles on the microstructure and properties of SDSS base and weld metal. READ MORE

4. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam
Abstract : Duplex stainless steels (DSSs), with a ferritic-austenitic microstructure, are used in a wide range of applications thanks to their high corrosion resistance and good mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding of the relations between composition, processing thermal cycles, resulting microstructures and properties.
