  1. 1. Sustainability of Additive Manufacturing : Electron Beam Melting of IN718

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik; Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Linda Alsing; Sandra Johansson Storm; [2019]
    Keywords : Additive manufacturing; aerospace industry;

    Abstract : 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. READ MORE

  3. 3. Thermodynamic Modelling and Experimental Investigation of Tungsten Partitioning in Nickel Based Alloys

    University essay from KTH/Materialvetenskap

    Author : Joshva Kumpati; [2018]
    Keywords : Calphad; Tungsten partitioning; Nickel based alloys; Thermo-Calc; Thermodynamic database; Ni-W binary; Calphad; volframpartitionering; Nickelbaslegering; Termo-Calc; Termodynamisk databas; Ni-W;

    Abstract : Thermo-Calc software AB develops high quality thermodynamic and kinetic databases to predict and simulate accurately multi-component phase behaviour in complex systems. One problem with their Ni-based alloys and superalloy solutions database (TCNI8) is poor description of tungsten partitioning for multi-component nickel based alloys. READ MORE

  4. 4. Effect of carbon activity on microstructure evolution in WC-Ni cemented carbides

    University essay from KTH/Materialvetenskap

    Author : Olivia Danielsson; [2018]
    Keywords : Cemented carbides; Hard metal; WC-Ni; Tungsten carbide; Nickel binder; Grain coarsening; Grain growth; Carbon activity; Size distribution; EBSD; Electron backscattered diffraction;

    Abstract : The aim of this work was to systematically study how the microstructure evolution is affected by the carbon activity in WC-Ni cemented carbides. Seven WC-9.59at%Ni alloys with different carbon activity were sintered at 1500 °C. READ MORE
