  4. 2. Process Understanding and Weldability of Laser-Powder Bed Fusion Manufactured Alloy 718

    Author : Tahira Raza; Joel Andersson; Lars-Erik Svensson; Boris Alexandrov; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser-Powder Bed Fusion; Alloy 718; Process Parameters; Heat Treatments; Weldability; Hot Cracking; Varestraint Testing; Laser-pulverbäddmetoden; Legering 718; Processparametrar; Värmebehandlingar; Svetsbarhet; Varmsprickor; Varestraintprovning; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Laser-powder bed fusion (L-PBF) is an additive manufacturing (AM) process that involves building components by fusing fine metal powders using laser. There is no universal set of process parameters that can yield optimum results for all the different materials, geometries, and L-PBF machines. READ MORE
