  1. 21. Process characterisation of an additive manufacturing equipment : An analysis of the effect of electron beam powder bed fusion process parameters on the melt pool geometry and microstructure of Ti-6Al-4V

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Ida Ljusell; [2023]
    Keywords : Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

    Abstract : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. READ MORE

  3. 22. Materials cleanliness assessment in rheocasting : An investigation in the melt quality in aluminum alloy casting

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Gustav Hellberg; [2022]
    Keywords : Melt quality; Density index; Bifilms index; RheoMetal casting; Aluminum casting; Degassing.;

    Abstract : The use of aluminum is a key factor in creating an Eco-friendlier automotive industry. The material has good properties and the ability to reuse the material. The requirement on the material in this industry is very high, due to the exposed working environments. READ MORE

  4. 23. Modelling Gas Flow Behaviour in Gas Atomizer

    University essay from KTH/Materialvetenskap

    Author : Aravind Senan Vasanthasenan Reji; [2022]
    Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

  5. 24. Wire and Arc Additive Manufacturing : Topology Optimised Vehicle Component

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Malte Petersson; [2022]
    Keywords : Wire and Arc Additive Manufacturing; Additive Manufacturing; WAAM; AM; Overhang; Cooling times; Simulation; Welding;

    Abstract : Wire and arc additive manufacturing (WAAM) is a manufacturing method using a numerical controlled motion system and a welding system to additively manufacture three dimensional components. The motion system is programmed from three dimensional computer aided design model data (3D-CAD) of the intended geometry which is then sliced in to layers and welded on additively. READ MORE

  6. 25. Study of process parameters in laser beam welding of copper hairpins

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Dan Lönn; David Spångberg; [2022]
    Keywords : Laser Welding; Hairpin Welding; Copper Laser Welding; Process Parameter; Multi-Physical Simulation; Computed Tomography Scan; Design of Experiment;

    Abstract : This study had the purpose to further the use of industrial lasers in the manufacturing of hairpin electric motors by optimizing the process of contacting the hairpins. A problem with laser beam welding of copper is the porosity created in the process which can lead to increased resistance of the welded region along with degraded mechanical properties. READ MORE
