  1. 26. Laser Metal Deposition using Alloy 718 Powder : Influence of Process Parameters on Material Characteristics

    Författare :Andreas Segerstark; Joel Andersson; Lars-Erik Svensson; Boian Alexandrov; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Laser metal deposition; Powder; Superalloy; Material characterization; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Additive manufacturing (AM) is a general name used for manufacturing methods which have the capabilities of producing components directly from 3D computeraided design (CAD) data by adding material layer-by-layer until a final componentis achieved. Included here are powder bed technologies, laminated object manufacturing and deposition technologies. LÄS MER

  3. 27. Fatigue Properties of Additively Manufactured Alloy 718

    Författare :Arun Ramanathan Balachandramurthi; Per Nylén; Robert Pederson; Johan Moverare; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Additive Manufacturing; Powder Bed Fusion; Superalloy; Microstructure; Surface roughness; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Additive Manufacturing (AM), commonly known as 3D Printing, is a disruptive modern manufacturing process, in which parts are manufactured in a layer-wise fashion. Among the metal AM processes, Powder Bed Fusion (PBF) technology has opened up a design space that was not formerly accessible with conventional manufacturing processes. LÄS MER

  4. 28. Towards understanding the fatigue behaviour of Alloy 718 manufactured by Powder Bed Fusion processes

    Författare :Arun Ramanathan Balachandramurthi; Per Nylén; Robert Pederson; Johan Moverare; Filippo Berto; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Additive Manufacturing; Powder Bed Fusion; Superalloy; Microstructure; Surface Roughness; Production Technology; Produktionsteknik;

    Sammanfattning : Additive Manufacturing (AM) is a disruptive modern manufacturing process in which parts are manufactured in a layer-wise fashion. Among the metal AM processes, Powder Bed Fusion (PBF) technology — comprised of Electron Beam Powder Bed Fusion (EB-PBF) and Laser Beam Powder Bed Fusion (LB-PBF) —has opened up a design space that was formerly unavailable with conventionalmanufacturing processes.

  5. 29. Microstructure Modelling of Additive Manufacturing of Alloy 718

    Författare :Chamara Kumara; Per Nylén; Johan Moverare; Lars-Erik Lindgren; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-Field Modelling; Additive Manufacturing; Phase Transformation; Solidification; Heat Treatment; Superalloy; Production Technology; Produktionsteknik;

    Sammanfattning : In recent years, additive manufacturing (AM) of Alloy 718 has received increasing interest in the field of manufacturing engineering because of its attractive features compared with those of conventional manufacturing methods. Nevertheless, owing to the inherent nature of the process, the build material is exposed to complex thermal conditions that affect the microstructure. LÄS MER

  7. 30. Microstructure Modelling of Additive Manufacturing of Alloy 718

    Författare :Chamara Kumara; Per Nylén; Johan Moverare; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-Field Modelling; Laser metal powder directed energy deposition; Electron Beam Melting; Heat Treatment; Superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : In recent years, additive manufacturing (AM) of Alloy 718 has received increasing interest in the field of manufacturing engineering owing to its attractive features compared to those of conventional manufacturing methods. The ability to produce complicated geometries, low cost of retooling, and control of the microstructure are some of the advantages of the AM process over traditional manufacturing methods. LÄS MER
