  1. 6. Laser powder bed fusion of 316L stainless steel - Microstructure and mechanical properties as a function of process parameters, design and productivity

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Alexander Leicht; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensile properties; productivity; design for additive manufacturing; additive manufacturing; thin-wall structures; stainless steel; laser powder bed fusion; microstructure; 316L;

    Abstract : One of the most common additive manufacturing techniques for fabricating metallic components is laser powder bed fusion, which has demonstrated great potential in fabricating parts with properties exceeding the properties achieved via conventional methods. To fully utilize the process’s potential, a more profound understanding of the microstructure and properties of the laser powder bed fusion processed material is required. READ MORE

    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

  3. 8. Process Development for Electron Beam Melting of 316LN Stainless Steel

    University dissertation from Sundsvall : Mid Sweden University

    Author : Stefan Roos; Mittuniversitetet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; beam deflection rate; electron beam melting; energy input; material properties; microstructure; powder bed fusion; process parameters; 316LN stainless steel;

    Abstract : Additive manufacturing (AM) is a technology that inverts the procedure of traditional machining. Instead of starting with a billet of material and removing unwanted parts, the AM manufacturing process starts with an empty workspace and proceeds to fill this workspace with material where it is desired, often in a layer-by-layer fashion.

  4. 9. Fatigue Properties of Additively Manufactured Alloy 718

    University dissertation from Trollhättan : University West

    Author : Arun Ramanathan Balachandramurthi; Högskolan Väst.; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 10. Electron beam melting of Alloy 718 Influence of process parameters on the microstructure

    University dissertation from Trollhättan : University West

    Author : Paria Karimi Neghlani; Högskolan Väst.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Powder bed fusion; Electron beam melting; Part’s orientation; Microstructure development; Single track; Energy input; Focus offset; Geometrical features; Alloy 718; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Abstract : Additive manufacturing (AM) is the name given to the technology of building 3D parts by adding layer-by-layer of materials, including metals, plastics, concrete, etc. Of the different types of AM techniques, electron beam melting (EBM), as a powder bed fusion technology, has been used in this study.
