3. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam
Sammanfattning : 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.
