  1. 1. Laser Welding and Additive Manufacturing of Duplex Stainless Steels : Properties and Microstructure Characterization

    Författare :Amir Baghdadchi; Leif Karlsson; Vahid Hosseini; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Technology; Produktionsteknik;

    Sammanfattning : Duplex stainless steels (DSS), with a ferritic-austenitic microstructure, are used ina wide range of applications thanks to their high corrosion resistance and excellent mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding o frelations between composition, processing thermal cycles, resulting microstructures and properties.
