  3. 2. Sustainability of Additive Manufacturing : Electron Beam Melting of IN718

    Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Författare :Linda Alsing; Sandra Johansson Storm; [2019]
    Nyckelord :Additive manufacturing; aerospace industry;

    Sammanfattning : The purpose of this thesis is to examine and describe the process of Additive Manufacturing (AM) and the energy use in the production of parts manufactured with the Electron Beam Melting (EBM) technology in particular IN718, which is a Nickel-based superalloy with specification according to UNS n07718 that is used in the aerospace industry. The objectives also include a brief overview of powder bed AM methods and a sustainability analysis. LÄS MER

  4. 3. The influence of grain size on mechanical properties of Inconel 718

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Muhammad Moiz; [2013]
    Nyckelord :Super alloys; Inconel 718; microscopy; grain size;

    Sammanfattning : The thesis work discuss about how the materials mechanical properties are influenced by the microstructure. The most common way of altering the microstructure of the material is by heat treatment.The mechanical properties that are of interest are strength, toughness, ductility, creep and fatigue. LÄS MER

  5. 4. Constitutive modelling of the nickel base superalloy IN718; a preparatory study

    Magister-uppsats, Hållfasthetslära

    Författare :David Gustafsson; [2008]
    Nyckelord :material model; superalloy; cyclic behaviour; Armstrong-Fredrick; LS-DYNA; FORTRAN;

    Sammanfattning : One of the limiting factors in gas turbine design is the allowable metal temperatures and loads in critical components. Specially designed superalloys are used when the conditions are most severe. One of these superalloys is Inconel 718. LÄS MER
